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“ in the balance. (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 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.

6 EMS-BA-e-1514

3 Basic Safety Precautions

3.1 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.

3.2 Personnel training

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

4 Transportation & Storage

4.1 Testing upon acceptance

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

4.2 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.

EMS-BA-e-1514 7

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.

Therefore, observe the following for the installation site:

• Place scales 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 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.
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.

5.2 Unpacking/installation

Carefully remove the balance from the packaging, remove plastic cover and setup
balance at the intended workstation.
The balance must be installed in a way that the weighing plate is exactly in horizontal
position.

Scope of delivery / serial accessories

• Balance

• Weighing plate

• Mains power supply

• Windshield, only EMS 300-3

• Instruction Manual

5.3 Mains conne ction

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 us ing 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 (see chapter 9.3).

 In weighing mode keep the UNIT key pressed 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.

EMS-BA-e-1514 9

If the batteries are run down, "LO" appears in the display. Press ON/OFF-key and
replace the batteries 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.

5.5 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. 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.

10 EMS-BA-e-1514

5.6 Linearization
(only models EMS 300-3, EMS 3000-2)

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”

error message; repeat linearization process.

EMS-BA-e-1514 13

5.7 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.

5.8 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 of the selected
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.

Parts counting

During piece counting p

arts 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

 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.
