Keyboard overview

Basic Information (General)

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 center of the weighing pan. As soon as a stable weighing value is reached the weighing value can be read.

2. Improper Use

   • 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 damaged 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.

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

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) quickly and at a moderate cost.

Basic Safety Precautions

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.

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

Transport and storage

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

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 pan, the power unit etc. against shifting and damage.

Unpacking, Setup and Commissioning

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:

• 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.

Unpacking and placing

• Open package, take out the appliance and accessories. Verify that there has been no damage and that all packing items are present.
• The balance must be installed in a way that the weighing pan is exactly in horizontal position.
• Mount the display unit in a way that facilitates operation and where it is easy to see.

Scope of delivery / serial accessories

• Platform and display unit, see chap. 2
• Mains adapter
• 4 x adjustable feet
• Wall fixture (with fixing screws)
• Operating manual

Mains connection

• Select a country-specific power plug and insert it in the power unit.
• Check, whether the voltage acceptance on the scales is set correctly. Do not connect the scales to the power grid 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 power plug at all times.

Battery operation

• On the rear side of the display unit remove the battery cover and connect 4 x 1.5V mignon cells. Reinsert the battery cover.
• In order to save the battery, the balance switches automatically off after 3 minutes without weighing. Additional switch-off times can be set in the menu (function “A.OFF”).
• If the batteries are depleted, the battery symbol is displayed. Switch off balance and replace batteries at once.
• 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.

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.

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.

An error message will be displayed in the event of an adjustment error or incorrect adjustment weight. Remove the adjustment weight and repeat the adjustment process.
Keep the adjustment weight close to the balance. Daily control of the weighing exactness is recommended for quality-relevant applications.

Operation

Start-up

Should the balance not display exactly zero despite empty weighing pan, press the button. The balance will be set to zero after a short standby time.

Switching Off

Taring

Hold function (animal weighing function)
The balance has an integrated animal weighing function (mean value calculation). Using this function it is possible to weigh domestic or small animals exactly (min. load 1% of the max. one), although they do not stand quiet on the weighing pan.

There is no average value calculation in the event of too much movement (heavy display oscillation).

Determination of the number of pieces
Before it is possible to determine the number of pieces by means of the scales, it is necessary to specify the average piece weight (unit weight), the so-called reference value. In order to do it, one shall place the specific number of pieces being counted up. By means of the scales, the total mass shall be determined which then will be divided by the number of pieces (the so-called reference pieces). Afterwards, based on the calculated average piece weight, counting up shall be carried out.

The greater the number of reference pieces, the higher the accuracy of counting up.

Menu

  • Before cleaning, 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.
  • Loose residue sample/powder can be removed carefully with a brush or manual vacuum cleaner.
  • Spilled weighing goods must be removed immediately.
• Servicing, maintenance
  • The appliance may only be opened by trained service technicians who are authorized by KERN.
  • Before opening, disconnect from power supply.
