3 Basic Information (General)

3.1 Proper use

The display unit acquired by you is used in combination with a weighing plate and serves to determine the weighing value of material to be weighed. It is intended to be used as a “non-automatic weighing system”, 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.

3.2 Improper Use

Do not use display unit 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” in the display unit. (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 weighing plate, minus a possibly existing tare load, must be strictly avoided. Both, the weighing plate and the display unit may be damaged during this process.

Never operate display unit in explosive environment. The serial version is not explosion protected.

Changes to the display unit's design are not permitted. This may lead to incorrect weighing results, safety-related faults and destruction of the display unit.

The display unit may only be operated in accordance with the described default settings. Other areas of use must be released by KERN in writing.

3.3 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 or damage by media, liquids, natural wear and tear
- The appliance is improperly set up or incorrectly electrically connected
• The measuring system is overloaded

3.4 Monitoring of Test Resources

In the framework of quality assurance the measuring-related properties of the display unit 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 display units' test substances and the test weights required for this. In KERN's accredited DKD calibration laboratory test weights and display units may be calibrated (return to the national standard) fast and at moderate cost.

4 Basic Safety Precautions

4.1 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.

4.2 Personnel training

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

5 Transport and storage

5.1 Testing upon acceptance

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

5.2 Packaging / return transport

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.

6 Unpacking and installation

6.1 Installation Site, Location of Use

The display units are designed in a way that reliable weighing results are achieved in common conditions of use.

Precise and fast work is achieved by selecting the right place for your display unit and your weighing plate.

On the installation site observe the following:

• Place the display unit and the weighing plate on a stable, even surface.
• Avoid extreme heat as well as temperature fluctuation caused by installing next to a radiator or in the direct sunlight;
• Protect the display unit and the weighing plate against direct draft from open windows or doors.
• Avoid jarring during weighing;
• Protect the display unit and the weighing plate against high humidity, vapours and dust.
• Do not expose the display unit 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.

Major display deviations (incorrect weighing results) may be experienced should electromagnetic fields (e.g. due to mobile phones or radio equipment), static electricity accumulations or instable power supply occur. Change location or remove source of interference.

6.2 Unpacking

Carefully remove the display unit from packaging, remove plastic cover and place it in the designated work area.

and place it in the designated work area.

Mount the display unit in a way that facilitates operation and where it is easy to see.

6.3 Scope of delivery / serial accessories:

• Display Unit
• Mains adapter
• Table leg
• Wall bracket
• Operating manual

6.4 Transportation lock (illustration example)

Please note: if the display unit is used together with platform with transportation lock, this transportation lock must be released prior to use:

6.5 Error message

As soon as an error message appears in the balance display, the balance must not more be used, e.g. Err 4

6.6 Placing

Mount the display unit in a way that facilitates operation and where it is easy to see.

There are many ways of positioning the display unit, such as free-standing or wall-mounted (optional).

Wall-mounted (optional)

Free standing

2. Fitting panel
3. Display Unit

6.7 Mains connection

Select a country-specific power plug and insert it in the mains adapter.

Check, whether the voltage acceptance on the scales is set correctly. Do not connect the scales to the power mains unless the information on the scales (sticker) matches the local mains voltage.

Only use KERN original mains adapter. Using other makes requires consent by KERN.

Important:

Before starting your weighing balance, check the mains cable for damage.
➢ Ensure that the power unit does not come into contact with liquids.
▶ Ensure access to mains plug at all times.

6.8 Storage battery operation (optional)

Before the first use, the battery should be charged by connecting it to the mains power supply for at least 12 hours.

If the weight display shows the flashing symbol 📄, this is an indication that the capacity of the rechargeable battery is almost exhausted. Charge the battery with the help of the supplied power pack.

6.9 Adjustment

As the acceleration value due to gravity is not the same at every location on earth, each display unit with connected weighing plate 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 weighing system 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 display unit periodically in weighing operation.

• Prepare the required adjustment weight. The adjustment weight to be used depends on the capacity of the weighing system. Carry out adjustment as near as possible to the weighing system's maximum weight. Info about test weights can be found on the Internet at: http://www.kern-sohn.com.
• Observe stable environmental conditions. Stabilisation requires a certain warm-up time.

Adjustment switch:

(example)

6.10 Linearization

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.

• In balances with a resolution of > 15 000 dividing steps carrying out a linearisation is recommended.
• 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 "Monitoring of test equipment".
• Observe stable environmental conditions. Stabilisation requires a certain warm-up time.
• After successful linearisation you will have to carry out calibration; see chapter 3.4 "Monitoring of test equipment".

Procedure:

→ Call-up menu item P3 CAL→Cal→Liner, see chap. 6.9
⇒ Confirm by 0 , the password query „Pn“ will be displayed.
⇒ Press , +CALO , subsequently. Ensure that there are no objects on the weighing pan.

7.10 Parts counting

Before the balance can count parts, it must know the average part weight (i.e. reference). Proceed by putting on a certain number of the parts to be counted. The balance determines the total weight and divides it by the number of parts, the so-called reference quantity. Counting is then carried out on the basis of the calculated average piece weight.

As a rule:

The higher the reference quantity the higher the counting exactness.

⇒ In weighing mode MR F0, press and hold until the message „P 10“ appears that is used to set the reference quantity.

⇒ Use TARE to set the desired reference quantity (such as 100), options include P 10, P 20, P 50, P100, P 200.

Place as many items to be counted (such as 100 items) as demanded by the set reference quantity and confirm by The weighing scales calculate the reference weight. The current quantity (such as 100 items) will be displayed.

→ Remove reference weight. The balance is from now in parts counting mode counting all units on the weighing plate.

→ Back to Weighing mode by MR F 3

7.11 Percent weighing

Percentage weighing allows you to display the weight in percent related to reference weight.

⇒ Press TARE in weighing mode (approx. 3 sec.) until "rEF 10%" is displayed.
⇒ Use TARE to set the desired percentage value to be applied as reference (selectable rEF 10, rEF 20, rEF 50, rEF 100, rEF 200, rEF 500).
Place a sample matching the set percentage value on the weighing platform and press 0 “----%” will be briefly displayed.

11 Instant help

In case of an error in the program process, briefly turn off the display unit 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 display unit is not switched on.
• Mains power supply interrupted (mains cable defective).
  • Power supply interrupted.
• (Rechargeable) batteries are inserted incorrectly or empty
• No (rechargeable) batteries inserted.

The displayed weight is permanently changing

• Draught/air movement
• Table/floor vibrations
• Weighing pan has contact with other objects.
• Electromagnetic fields / static charging (choose different location/switch off interfering device if possible)

The weighing result is obviously incorrect

• The display of the balance is not at zero
- Adjustment is no longer correct.
• Great fluctuations in temperature.
• Warm-up time was ignored.
- Electromagnetic fields / static charging (choose different location/switch off interfering device if possible)

Should other error messages occur, switch display unit off and then on again. If the error message remains inform manufacturer.

12 Installing display unit / weighing bridge

- Installation / configuration of a weighing system must be carried out by a well acquainted specialist with the workings of weighing balances.

12.1 Technical data

Supply voltage 12 V / 1000mA
Max. signal voltage 5V
Zeroing range 0-2mV
Sensitivity ≥ 0.15uV/d
Resistance parameter	87 - 1100 Ω

12.2 Weighing system design

The display unit is suitable for connection to any analogue load cell in compliance with the required specifications.

The following data must be established before selecting a load cell:

- Weighing balance capacity

This usually corresponds to the heaviest load to be weighed.

- Preload

This corresponds to the total weight of all parts that are to be placed on the weighing cell such as upper part of platform, weighing pan etc.

• Total zero setting range

This is composed of the start-up zero setting range ( ± 2%) and the zero setting range available to the user via the ZERO-key (2%). The total zero setting range equals therefore 4 % of the scale's capacity.

The addition of weighing scales capacity, preload and the total zero setting range give the required capacity for the weighing cell.

To avoid overloading of the weighing cell, include an additional safety margin.

- Smallest desired display division

12.3 How to connect the platform

→ Disconnect the display unit from the power supply.
Solder the individual wires of the load cell cable to the printed circuit board (See fig.).

Close-up of a green electronic circuit board with terminal connectors and pin labels (no readable text or symbols beyond component markings)

In 4-wire load cells or connection boxes (junction boxes), bridge the solder joints J1 and J2.
