Capacity display Display of units Stability display15 PBS/PBJ-BA-def-2319 English 4 Basic Information (General)

The balance you purchased is intended to determine the weighing value of material to be weighed. It is intended to be used as a “non-automatic balcance”, i.e. the material to be weighed is manually and carefully placed in the centre of the weighing pan.. As soon as a stable weighing value is reached the weighing value can be read.

Do not use balance for dynamic add-on weighing procedures, if small amounts of goods to be weighed are removed or added. The “stability compensation“ installed in the balance may result in displaying an incorrect measuring value! (Example: Slowly draining fluids from a container on the balance.) Do not leave permanent load on the weighing pan. This may damage the measuring system. Impacts and overloading exceeding the stated maximum load (max) of the balance, minus a possibly existing tare load, must be strictly avoided. Balance may be damage by this. Never operate balance in explosive environment. The serial version is not explosion protected. The structure of the balance may not be modified. This may lead to incorrect weighing results, safety-related faults and destruction of the balance. The balance may only be used according to the described conditions. Other areas of use must be released by KERN in writing.

Warranty claims shall be voided in case

• Our conditions in the operation manual are ignored

• The appliance is used outside the described uses

• The appliance is modified or opened

• Mechanical damage or damage by media, liquids, natural wear and tear

• The appliance is improperly set up or incorrectly electrically connected

• The measuring system is overloadedPBS/PBJ-BA-def-2319 16 English

4.4 Monitoring of Test Resources

In the framework of quality assurance the measuring-related properties of the balance and, if applicable, the testing weight, must be checked regularly. The responsible user must define a suitable interval as well as type and scope of this test. Information is available on KERN’s home page (www.kern-sohn.com with regard to the monitoring of balance test substances and the test weights required for this. In KERN's accredited DKD calibration laboratory test weights and balances may be calibrated (return to the national standard) fast and at moderate cost. 5 Basic Safety Precautions

5.1 Pay attention to the instructions in the Operation Manual

Carefully read this operation manual before setup and commissioning, even if you are already familiar with KERN balances.

5.2 Personnel training

The appliance may only be operated and maintained by trained personnel. 6 Transport and storage

6.1 Testing upon acceptance

When receiving the appliance, please check packaging immediately, and the appliance itself when unpacking for possible visible damage.

Keep all parts of the original packaging for a possibly required return. Only use original packaging for returning. Prior to dispatch disconnect all cables and remove loose/mobile parts. Reattach possibly supplied transport securing devices. Secure all parts such as the glass wind screen, the weighing platform, power unit etc. against shifting and damage.17 PBS/PBJ-BA-def-2319 English 7 Unpacking, Setup and Commissioning

7.1 Installation Site, Location of Use

The balances are designed in a way that reliable weighing results are achieved in common conditions of use. You will work accurately and fast, if you select the right location for your balance. Therefore, observe the following for the installation site:

• Operate the device only indoors.

• Place the balance on a firm, level surface;

• Avoid extreme heat as well as temperature fluctuation caused by installing next to a radiator or in the direct sunlight;

• Protect the balance against direct draughts due to open windows and doors;

• Avoid jarring during weighing;

• Protect the balance against high humidity, vapours and dust;

• Do not expose the device to extreme dampness for longer periods of time. Non-permitted condensation (condensation of air humidity on the appliance) may occur if a cold appliance is taken to a considerably warmer environment. In this case, acclimatize the disconnected appliance for ca. 2 hours at room temperature.

• Avoid static charge of goods to be weighed or weighing container. If electro-magnetic fields or static charge occur, or if the power supply is unstable major deviations on the display (incorrect weighing results) are possible. In that case, the location must be changed.

7.2 Unpacking / Scope of delivery

Remove device and accessories carefully from packaging, remove packaging material and place device at the planned work place. Verify that there has been no damage and that all packing items are present.PBS/PBJ-BA-def-2319 18 English Scope of delivery / serial accessories: Models with readability d = 0.001 g: Models with readability d ≥ 0.01 g:

• Operating instructions

Remove transport guard (models PBJ)

To loosen the transport guard, turn both transport screws [1] anti-clockwise until they are locked (refer to sign [2]). For transport, turn both transport screws clockwise until they are locked. Mount safety hood Remove protective foil from adhesive strips and mount the safety hood so that it does not contact the weighing plate.PBS/PBJ-BA-def-2319 20 English Levelling

Turn in all three foot screws [1] as far as they go.

Slightly press down the left front side of the scale and turn out the two front foot screws until the air bubble [3] in the spirit level [2] is within the prescribed circle. While continuing to exert a slight pressure to the front side of the scale, turn out the rear foot screw until the scale stands in stable position. Check levelling regularly.21 PBS/PBJ-BA-def-2319 English Installation of weighing plate Models with readability d ≥ 0.01 g:PBS/PBJ-BA-def-2319 22 English Models with readability = 0.001 g:

Remove rubber plug as shown in picture.

Attach wind guard and fix it by means of screws.

Install weighing pan as per illustration. Note the correct position.

Place the wind guard cover.23 PBS/PBJ-BA-def-2319 English

7.4 Mains connection

Power is supplied via the external mains adapter. The stated voltage value must be the same as the local voltage. Only use original KERN mains adapters. Using other makes requires consent by KERN.

Models PBJ: Prior to mains connection, loosen the transport guard screws at the scale according to the sign in any case, see chapter 7.3

7.5 Switch power supply on

Supply power to balance via mains adapter. The display lights up and the balance carries out a selftest.

Models PBS After a successful selftest „OFF“ is displayed. To switch on press the ON/OFF button. The balance will carry out a display test. As soon as the weight display appears, the balance is ready for weighing.PBS/PBJ-BA-def-2319 24 English

7.6 Connection of peripheral devices

Before connecting or disconnecting of additional devices (printer, PC) to the data interface, always disconnect the balance from the power supply. With your balance, only use accessories and peripheral devices by KERN, as they are ideally tuned to your balance. Terminal for external devices:

Interfaces at the balance back

7.7 Initial Commissioning

In order to obtain exact results with the electronic balances, your balance must have reached the operating temperature (see warming up time chap. During this warming up time the balance must be connected to the power supply (mains, accumulator or battery). The accuracy of the balance depends on the local acceleration of gravity. Strictly observe hints in chapter Adjustment.

125 PBS/PBJ-BA-def-2319 English 8 Adjustment As the acceleration value due to gravity is not the same at every location on earth, each balance must be coordinated - in compliance with the underlying physical weighing principle - to the existing acceleration due to gravity at its place of location (only if the balance has not already been adjusted to the location in the factory). This adjustment process must be carried out for the first commissioning, after each change of location as well as in case of fluctuating environment temperature. To receive accurate measuring values it is also recommended to adjust the balance periodically in weighing operation.

Observe stable environmental conditions. A warming up time (see chapter 1) is required for stabilization. Ensure that there are no objects on the weighing pan.

8.1 Manual adjustment by CAL button

The scales have been set by the manufacturer so that adjustment can be started directly from the weighing mode using the CAL button.

8.4 Automatic adjustment by Clock-CAL (model PB only)

With the help of its internal adjusting weight and integrated clock the balance can be set to carry out automatic adjustment at set times (up to three times daily, „ACALt1“, „ACALt2“ und „ACALt3“). Clock-CAL is a very convenient function, when calibration logs are desired to be made for regular calibrations, or when wishing span calibrations during break times to avoid interruption of measurement work. In order to execute Clock-Cal the following conditions must be met at the defined time. If the conditions are not met within one minute, adjustment is skipped. o The scale must be in weighing or standby mode. o The stability display must be indicated. o The load at the weighing plate must be near zero. o No other adjustment process must be started.

o The weight symbol blinks for about two minutes as notification of span calibration before it begins. o In order to avoid that adjustment is started possibly during a series of measurements, actuate as soon as the weight symbol flashes. This will interrupt automatic adjustment. o If all three times ate set to „00:00“ the function is switched off.35 PBS/PBJ-BA-def-2319 English Setting the time for Clock-CAL: Example „ACALt1“ to 12:00 p.m..

Verification notes: An EU type approval exists for balances described in their technical data as verifiable. If a balance is used where obligation to verify exists as described above, it must be verified and re-verified at regular intervals. Re-verification of a balance is carried out according to the respective national regulations. The validity for verification of balances in Germany is e.g. 2 years. The legal regulation of the country where the balance is used must be observed!

Verification of the balance is invalid without the seal. The seal marks attached on verified balances point out that the balance may only be opened and serviced by trained and authorised specialist staff. If the seal mark is destroyed, verification looses its validity. Please observe all national laws and legal regulations. In Germany a re-verification will be necessary.

Select menu element 66 is the date shall be displayed, see chapter 11.1

If the time is displayed in standby mode, you have the following functions available

• Display of seconds Using you can activate display/hiding of seconds.

• Correction by ±30 seconds: Actuate while the seconds are displayed. If the value is between

00 - 29 seconds, the seconds are rounded off to zero. If the value is

between 30 -59 seconds, it is round up by one minute and 00 is displayed for seconds.51 PBS/PBJ-BA-def-2319 English 13 Functions for adaptation to ambient conditions

13.1 Stability and reaction (average value)

Exists the possibility to tune the stability of the display and the degree of reaction of the balance to the requirements of certain applications or the installation environment. There is a possibility of selection among five operating modes. Please note that in general slowing down reaction times result in higher stability of the set data handling, while speeding up reaction times have an influence on the stability deterioration. However, the balances of PBS/PBJ type are designed to ensure both properties i.e. fast reaction time and high stability.

13.1.1 Automatic mode

Select the menu element 22: The balance automatically and dynamically undertakes to optimally determine the average value during observation of load data. If there are not any special circumstances, this setting should always be used.

Select the menu element 23: This mode is suitable for weighing invariable liquid volumes. It is very susceptible to wind and vibration. (When the filling mode is active, the button makes it possible to switch over between 3 stability settings.)

13.1.3 Standard mode

Select the menu element 24: This mode is suitable for weighing in normal environment. The determination of the average value is fixed and is not subject to adaptation as in the automatic mode which is performed dynamically.

13.1.4 Antivibration mode

Select the menu element 25: This mode should be used if the balance is placed at a location where there are strong vibrations, and its readings fluctuate in automatic mode. The balance reaction is deteriorated in a result of small changes of weight.

13.1.5 Antiwind mode

Select the menu element 26: This mode should be used if the balance is placed at a location where it is exposed to air currents which cause fluctuations of its readings in automatic mode. This reaction is deteriorated even more than in the antivibration mode, but the weighing process is more stable. MODEPBS/PBJ-BA-def-2319 52 English

13.2 Stability Detection Band

(up to 8 counts for verifiable, up to 64 counts for non verifiable models) The band makes it possible to select conditions at which the balance should be considered as stable. If „1 count” is selected, and the reading (within counting the readings) remains constant, the balance is considered as stable and the stability display is shown. The stability detection band can be set from 2 to 64 counts. Select the menu element:

Tracking is the function which ensures to receive present value displaying in possible long period. To ACTIVATE this function, select the menu element 34. To DEACTIVATE this function, select the menu element 35. 14 Capacity display This function displays a bar graph representation of the load on the weighing pan. This may be used to prevent sudden appearance of “oL” (overload) during measurement. Select the menu element 11 in the menu overview to set the full range mode: (1)

The bar located within the lower scale range indicates that the weight located on the scale pan is small. (1)

The bar approaching the upper scale range indicates that the weight located on the scale pan almost reaches the balance capacity. (2)

If the bar graph is not to be displayed, press the menu element 2153 PBS/PBJ-BA-def-2319 English 15 Switch-over weighing unit Press the button several times to switch over the display between the activated units. The default setting provides the following options: [g] → [%] → [PCS] → [%] Other settings must be activated in the menu as follows:

(Example) Menu overview No. 54 to 62 : Press button to switch over between the units. Save the selected unit using button

„SET“ appears shortly. The unit has been accepted.

In weighing mode, press the key repeatedly until the „%” symbol will be seen on the display. Setting 100% of the reference value:

Press the key to tare the balance.

Put the reference sample which represents 100% value. This value must correspond to 100 or more counts in „g” unit.

When the stabilisation display appears, press the key at once.

„SET“ appears shortly.

The reference sample weight will be shown as 100%.

Weights of next samples will be displayed as a percent value of the reference sample weight.

With parts counting you can either count parts into a container or remove parts from a container. To count a greater number of parts the average weight per part has to be determined with a small quantity (reference quantity). The larger the reference quantity, the higher the counting exactness. High reference must be selected for small parts or parts with considerably different sizes. The process has four steps:

• Tare the weighing container

• Determine the reference unit

• Weigh in the reference unit

Condition: Activate the PCS function with the menu element 57 if it is not set. (The unit of PCS function is factory set.) Make sure that the balance is in the weighing mode. (the unit of „g” is displayed)

Press the button repeatedly until the „PCS” symbol is displayed.

Place the container on the balance plate and tare the balance with the button.

Count exactly 9 (or 10, 20, 50, 100 or 200) pieces of the sample to be weighed and put them into the container.

Press the button when the display corresponds to the number of the pieces being put. The reference quantity is saved.

16.2 Control weighing and target weighing

16.2.3 Target weighing mode

This mode is used for weighing constant liquid quantities or for assessment of missing quantities or excess quantities. The target value is the numeric value which corresponds to the nominal quantity of the used unit. The target value is a numerical value which corresponds to quantity of the set unit to be used for weighing. The target value on the analogue display is presented as the centre line. The limit values are indicated with the triangle symbols. The movable bar presents the current weight on the scale pan. The target weighing mode is selected with the menu element 12. Display elements used

The „target value”, which corresponds to the centre line on the graphic display, is to be set with the menu element 13.

The „limit value”, which corresponds to the distance between the centre line and upper or lower triangle symbol, is to be set with the menu element 14.

To carry out the density determination of solids and liquids please refer to the user manual which KERN delivers together with the density determination kit.

The „zero range“ is used as a reference value, whether a sample was placed or not. To determine the zero range, select the menu element 48 .

16.8 Taring /printing at stability (models PBJ)

(only in verifiable units) Determine if the balance first has to reach stability before printing via the button or the zero point can be displayed via the button. If you want to print or to tare without waiting for stability: (immediate operation)

• Select the menu element 39. If printing or taring only after having reached stability: (waiting for stability)

• Select the menu element 40. Notes: While the balance waits for stability, „----“ is displayed.

• Press button, then „---“ appears. At this opportunity press the button, if you deactivate this function and want to cancel taring.

• If the communication - and the standby symbol are illuminated and you press the button, you have to wait for the stability symbol . The data are output, when the stability symbol is illuminated. If during waiting time you press the button, the balance goes to standby mode. Data are printed as soon as in the next weighing process stability has been reached.

This mode is used for convenient weighing of individual recipe components. Weights of each component are displayed and saved after each pressing the button. The weights of those component are sent with the RS-232C or DATA I/O interface, and the display is automatically zeroed to weigh the next component. When all components are weighed, their weights are added up and the total weight is displayed. This value output is edited by the button. Select the menu element 51 in the menu overview.

• 1. If the recipe mode is activated, the display is in the recipe stand-by mode until it is started. The display shows the Add-On symbol, memory symbol and stand-by mode symbol. Place the container (if used) and press the button to tare it. Please remember that taring with the button will not be accepted after previous pressing the button (as in the step 2). Taring is possible again after previous pressing the button (as in the step 5).

• 4. Step 3 is to be repeated for all components to be weighed.

• 5. Then press the button. The total weight will be displayed and output to peripheral devices with the „TOTAL=” unit.

• 6. Remove everything from the balance plate. The next recipe is started from the step 1.

16.10 Automatic saving and zeroing

This function is used for weighing large number of single samples. If the function is activated, the automatic saving and zeroing symbol is illuminated. Select the menu element 52 in the menu overview.

• Place the container to be weighed on the balance and press the button when the automatic saving and zeroing function is in the stand-by mode. (The automatic saving and zeroing symbol and mode symbol are illuminated.) The balance will be zeroed.

• Press the button. The stand-by symbol disappears and measurements within the automatic saving and zeroing function can be started.

• Place the first sample on the scale pan. Each time when the stabilisation symbol is illuminated and the value corresponding to five times the zero range or higher is illuminated or when the button is pressed, the illuminating value output and balance zeroing is carried out.

• Weighing process of the next sample is carried out without the necessity to press the button.

• Press the button. The balance returns to the stand-by mode of the automatic saving and zeroing function, the total weight placed on the scale pan without the packaging weight is displayed. To print this value, press the button. Notes:

• If the stabilisation symbol is illuminated and the display value lies within the zero range, zeroing is carried out automatically.

• Pressing the button when the display value lies below five times the zero range is followed by zeroing after data output. (Manual loading)

• Pressing the button when the automatic saving and zeroing function is in stand-by mode is also followed by setting mains supply in stand-by mode. TARE / PRINT PRINT ESC ON/OFF ESC ON/OFF PRINT PRINT ESC ON/OFFPBS/PBJ-BA-def-2319 62 English

16.11 Animal weighing

(only possible with non verifiable setting) This function is used for weighing animals. The animal symbol is displayed when the animal weighing mode is active. Select the menu element 53 in the menu overview.

• Place the weighing container on the scale pan and press the button. Note: When the weighing container is placed on the scale pan, data output is possible. It is not a fault. This no malfunction.

• Place an animal on the scale pan. Its weight must exceed 50 times the zero range.

• The value will be given automatically when the weighing value is stabilised.

• Press the button or remove an animal from the scale pan.

• If the displayed value is stable, but it lies below 10 times of the zero range, the balance will be zeroed automatically. Any remaining materials on the scale pan (excrement or skin) will be automatically written off and zeroed. If the balance is not zeroed, the zero range value must be increased (refer to

• The stand-by mode is not provided for the animal weighing function.

• Press the button to switch over to the mains supply stand-by mode.

• When live animals are weighed in the animal weighing mode, automatic extension of stability detection band is carried out. Repeatability of measuring data is a bit lower than in other operational modes.

• If an animal being weighed cannot be controlled and the automatic printing function does not respond, you can press the button to output the display value. Then remove an animal from the balance. Even if the stability symbol appears before an animal is removed from the balance, the data will not be printed again.

• The stability symbol will appear earlier due to setting the wider stability detection band in the menu.

• If the balance returns to the zero point too slowly, the zero range is to be set to a higher value.

17.1.1 Connecting the Cable

ATTENTION: By using the RS-232C/AUX interface of the PBS/PBJ type balances it is also possible to output other signals than RS-232C ones. Incorrect connection of those signal cables may lead to the personal computer or balance failure. Therefore, make sure that the suitable and correctly connected cable provides communication between the balance and computer. Some types of computers may not operate normally when they are connected by using the optional RS-232C cable in the way shown in the below figure. (1) IBM PC/AT computer and compatible (9-pin D-sub connector)

The following explanations refer to the case when the menu element 77 (EB type format) is selected. Explanations concerning other formats are included in the data of computers compatible with the suitable data formats. Note: The mark indicates the space code, and <Limiter> indicates the limiter code.

1. For measuring values:

from 2. to 11. sign: Numerical values or „[”, ”]” are right justified. Position of the decimal point is changed depending on the device type.

from 12. to 13. sign: Units such as g􀂅 or kg

• If the CR or LF command is the limiter (the menu element 94 or 95 is selected), sign 13 is not available.

• When stability information is printed, the first of the above mentioned signs is preceded with the following sign: Stable time: S Instable time: D

17.3 Using codes of commands

Note: Incorrect setting of communication parameters results in displaying the communication error „ComErr”.

1. Commands ending with a digit, letter or symbol different than [=]:

commands to the balance must be transmitted with a limiter for each command code.

Example 1: PRINT<CR> ... The same process as after pressing the button.

2. Commands ending with the [=] sign: Digits must be transmitted with a limiter to the

Example 2: TIME=1234 <CR> .. The time of 12:34 is set as the current time

Example 3: P.TARE=1.23 <CR> (example for two positions after the point). The value of 1,23 g is set as the initial taring value.

Example 4: P.TARE=0.00 <CR> (example for two positions after the point). ... cancels (writes off) the initial taring value.

Note: Number of positions, decimal point and position of the decimal point in the number sign transmitted after the ‘=’ sign are the same as they would be for entering numerical value with the buttonboard. Use the same number of places after the point as in the weighing mode. This limitation does not refer to USER=, SOLID= and LIQUID= commands.

• If 0 is at the beginning of the four-position number, the setting is finished at this point, and the menu selection is finished.

• The result of such a command depends on the balance type. Example 6: #=2.56 <CR>

Example 7: #=12.345.67 <CR> A computer makes it possible to determine the specified presentation way of numbers for processes of weighing and displaying on the balance. In the case of commands from examples 6 and 7, the values of [#2.56] and [#12.345.67] are displayed on the balance. When the button is pressed, the ’2-56<CR>’ and ’12-345-67<CR>’ strings are sent from the balance.

3. Return message command

The balance sends back the N string of signs which are limited by the return message command ‘{‘ or ’}’ and limiter. In the receive buffer of the balance there are not left any not processed return message commands for N ≤30.

Example 8: ABCDEFG12345<CR> ... When this command is received, the balance sends ABCDEFG12345<CR> string. This string can be printed by the printer.

Note: Only capital letters and part of symbols (decimal point, decimal symbol etc.) can be used for data output with an electronic printer. Maximal length of line is 15 characters.
