2 Basic Information (General)
2.1 Proper use
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 balance”, i.e. the material to be weighed is manually and carefully placed in the centre of the weighing plate.. As soon as a stable weighing value is reached the weighing value can be read.
2.2 Improper Use
Do not use balance for dynamic weighing. In the event that small quantities are removed or added to the material to be weighed, incorrect weighing results can be displayed due to the “stability compensation”. (Example: Slowly draining fluids from a container on the balance).
Do not leave permanent load on the weighing plate. 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.
2.3 Warranty
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 and damage caused by media, liquids
- natural wear and tear
- The appliance is improperly set up or incorrectly electrically connected
• The measuring system is overloaded
2.4 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 Unpacking, Setup and Commissioning
5.1 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.
On the installation site observe the following:
- 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 and weighing container.
- Do not operate in areas with hazard of explosive material or in potentially explosive atmospheres due to materials such as gasses, steams, mists or dusts.
- Keep away chemicals (such as liquids or gasses), which could attack and damage the balance inside or from outside.
- Keep IP protection of the device.
- 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.
5.2 Unpacking/installation
Carefully remove the balance from the packaging, remove plastic cover and setup balance at the intended workstation.

Level balance with foot screws until the air bubble of the water balance is in the prescribed circle.
5.3 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.
5.4 Operation using a rechargeable battery (optional)
Lift-off the battery cover on the lower side of the balance. Connect 9 V compound battery.
Replace the battery compartment cover.
For battery operation the balance has an automatic switch-off function which can be activated or deactivated in the menu.
In weighing mode keep the PRINT key pressed until "Unit" appears.
⇒ Press MODE key repeatedly until „AF“ appears.
→ Use the SET key to confirm.
→ Use the MODE key to choose between the two following settings:
„AF on“: In order to save the battery, the balance switches automatically off after 3 minutes without weighing.
„AF off“: Switch-off function deactivated.
→ Use the SET key to confirm selection. The balance returns to weighing mode.
The empty battery is indicated on the display by "LO". Press ON/OFF-key and replace the battery immediately.
If the balance is not used for a longer time, take out the batteries and store them separately. Leaking battery liquid could damage the balance.
If there exists an optional rechargeable battery, it has to be connected in the battery compartment via a separate plug-in socket. Now the mains adapter delivered with the rechargeable battery must be applied.

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.
5.6 Initial Commissioning
In order to obtain exact results with the electronic balances, the balance must have reached the operating temperature (see warming up time chap. 1. 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.
5.7 Linearisation
(only models PCD 250-3, PCD 2500-2)
Linearity shows the greatest deviation of a weight display on the scale to the value of the respective test weight according to plus and minus over the entire weighing range.
If linearity deviation is discovered during a monitoring of test resources, you can improve this by means of linearization.
- Carrying out linearization is restricted to specialist staff possessing well acquainted with the workings of weighing scales.
- The test weights to be used must be adapted to the weighing scale's specifications; see chapter 3.4 "Testing instruments control".
- Observe stable environmental conditions. Stabilisation requires a certain warm-up time.
- After successful linearization you will have to carry out calibration; see chapter 3.4 "Testing instruments control"

| Finally the balance will switch off automatically. Now the linearization is concluded successfully. | |
In case of an adjustment error or incorrect adjusting weight the display will show an error message; repeat linearization process.
5.8 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.
5.9 Adjustment
The adjustment should be made with the recommended adjustment weight (see chap. 1 "Technical data"). Adjustment is also possible with the weights of other nominal values (see table 1), but not the optimum for measuring technique.
Procedure when adjusting:
Observe stable environmental conditions. A warming up time (see chapter 1) is required for stabilization.
⇒ Turn on balance by pressing the ON/OFF key.
⇒ Press the MODE key and keep it pressed, in the display appears shortly „CAL“. After that the exact size appears flashing in the display (see chapter. 8.3.3) of the adjustment weight.
→ Now set the adjusting weight in the centre of the weighing plate.
⇒ Press the SET key. Short time later there appears „CAL F“, then the automatic return to the weighing mode. In the display there appears the value of the adjustment weight.
An error during adjustment or the use of an incorrect adjusting weight will result in an error message „CAL E“. Repeat adjustment.
Keep the adjustment close to the balance. Daily control of the weighing exactness is recommended for quality-relevant applications.

In weighing mode put tare vessel on the weighing plate
⇒ Press repeatedly the MODE key until „PtArE“ flashing appears.
⇒ Use SET key to store the current weight on the weighing plate as a PRE-TARE value.
Delete PRE-TARE value
→ Unload the balance and set the TARE button to zero
⇒ Press repeatedly the MODE key until „PtArE“ flashing appears.
⇒ Use the SET key to confirm. The PRE-TARE value is deleted, the zero display appears.
7.6 Plus/minus weighings
For example unit weight control, fabrication control etc.
⇒ Put the nominal weight on the weighing plate and tare using the TARE button.
→ Remove the nominal weight
⇒ Put the test objects subsequently on the weighing plate, the respective deviation from the nominal weight is displayed with the respective sign to „+“ and „-“.
According to the same procedure also packages with the same weight can be produced, referring to a nominal weight.
→ Back to weighing mode by pressing the TARE button.
7.7 Parts counting
During piece counting parts can either be counted into a container or out of 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 larger the reference quantity, the more accurate the parts counting.
The process has four steps:
Tare the weighing container
Determine the reference unit
Original weighing of reference weight
Count the items
i
In weighing mode press MODE key shortly. Reference piece number „5 ^PCS “ appears flashing.
⇒ By pressing the MODE button several times other reference quantities 5, 10, 20, 25 and 50 can be called up. Place as many pieces to count on the weighing plate as the set reference quantity requires.
Use the SET key to confirm. The balance is now in parts counting mode counting all units on the weighing plate.
- Back to weighing mode by pressing the MODE button.
- Error message „Er 1“ Piece below minimum weight of piece (See chpt. 1 "Technical specifications"): Press MODE key and restart reference determination.
- Taring The tare vessels can also be used for piece counting. Before starting piece counting use the TARE button to tare out the container.
7.8 Net-total weighing
It is useful if a mixture of several components is weighed into a tare vessel and finally the sum weight of all weighed components is necessary for control purposes (net-total, i.e. the weight of the tare vessel).
Example:
- Place tare container on the weighing plate. Press the TARE button, the zero display disappears.
- Weigh-in component ①. Press the SET button, the zero display disappears. [▲] is displayed on the right border of the display.
- Weigh-in component ② and press SET key. Net-total (sum weight of the components ① and ②) is displayed.
- Press the SET button, the zero display disappears.
- Weigh-in component ③ and press SET key. Net-total (sum weight of the components ① and ② and ③.) is displayed.
If necessary, also fill the formula up to the desired final value. For every component more repeat the steps 4-5.
→ Back to weighing mode by pressing the TARE button.
7.9 Percent determination
Percentage calculation facilitates weight display in percent related to a reference weight equivalent to 100 %.
In weighing mode press MODE key repeatedly, until "100 %" is displayed flashing.
⇒ Put a reference weight which corresponds to 100 %.
⇒ Store by pressing the SET key. If the display stops flashing, remove the reference weight.
Place goods to be weighed on balance. The weight of the sample is displayed in percentage in terms of the reference weight.

9.4 Output on bar code printer
The data transfer mode has to be set on „BA Pr“ (chapter 8.4.1).
As bar code printer the Zebra printer model LP2824 is provided.
Take into account that the output format of the balance is fixedly defined and cannot be changed.
The printer format is stored in the printer, i.e. in case of a failure the printer cannot be changed with a new one from factory, previously it is necessary that KERN installs the respective software.
The Zebra printer and the balance must be connected to the delivered interface cable when they are switched off.
After switching-on both appliances, and after reaching the status ready-for-operation, a label will be printed out when pressing the PRINT button.
10 Service, maintenance, disposal
10.1 Cleaning
Before any maintenance, cleaning and repair work disconnect the appliance from the operating voltage.
Please do not use aggressive cleaning agents (solvents or similar agents), but a cloth dampened with mild soap suds. Take care that the device is not penetrated by fluids and polish it with a dry soft cloth.
Clean the stainless-steel parts with a soft cloth soaked with a cleaning agent suitable for stainless steel.
For stainless steel parts do not use any cleaning agents which contain sodium hydroxide solution, acetic, hydrochloric, sulphuric or citric acid.
Do not use metal brushes or cleaning sponges of steel wool, as this causes superficial corrosion.
10.2 Service, maintenance
⇒ The appliance may only be opened by trained service technicians who are authorized by KERN.
⇒ Ensure that the balance is regularly calibrated, see chap. Testing instruments control.
10.3 Disposal
Disposal of packaging and appliance must be carried out by operator according to valid national or regional law of the location where the appliance is used.

In case of an error in the program process, briefly turn off the balance and disconnect from power supply. The weighing process must then be restarted from the beginning.
Help:
Fault Possible cause
The displayed weight does not glow.
- The balance is not switched on.
- The mains supply connection has been interrupted (mains cable not plugged in/faulty).
• Power supply interrupted. - Battery is inserted incorrectly or is empty.
- No batteries inserted.
The displayed weight is permanently changing
- Draught/air movement
• Table/floor vibrations - The weighing plate is in contact with foreign matter.
- Electromagnetic fields / static charging (choose different location/switch off interfering device if possible)
The weighing value is obviously wrong
• The display of the balance is not at zero
- Adjustment is no longer correct.
• Great fluctuations in temperature.
- Electromagnetic fields / static charging (choose different location/switch off interfering device if possible)
Should other error messages occur, switch balance off and then on again. If the error message remains inform manufacturer.
