1 Introduction
Thank you for purchasing a KERN WTB scale. These scales are rugged, simple to operate, and can be
used without connection to an external power supply. The scale has a menu system which allows it to
be adapted to your needs.
Please read through these Operating Instructions carefully, and always follow them!
1.1 Safety and the environment
–Read through these Operating Instructions carefully, even if you already have ex-
perience of KERN scales. Only ever use your scale as described in the Operating
Instructions. Be sure to follow the instructions for putting your new scale into
operation.
–Do not use the scale in a explosive environment.
– ForconnectiontothepowersupplyuseonlytheACadapterdelivered withthescale.
Beforeyou connect the scaleto the power supplycheck that the voltagestated on the
AC adapter is the same as the local power supply voltage. If it is not, do not connect
the AC adapter under any circumstances but contact your dealer.
– Although your scale is very ruggedly constructed, it is nevertheless a precision
instrument.Impactstotheweighingpan,orplacingexcessivelyheavyloadsonit,can
damage the scale.
–Observelocalandnationalenvironmentalregulationswhendisposing of thescale.
The scale is fitted with a storage battery that contains heavy metals. Do not dispose
ofthebatteryas normalwaste!Observelocalregulationsfordisposalof environmen-
tally harmful substances.
1.2 Selecting a location
Selectingasuitablelocationmakesadecisivecontributiontoprecisemeasurementresults
and lengthens the service life of the scale:
– Choose a stable, vibration-free surface which is as horizontal as possible.
– Ensure there are no excessive fluctuations in temperature, and no direct sunlight.
– Make sure that the environmental conditions are met (Chapter 9.1).
– Avoid drafts (e.g. from fans or air conditioning).
– Afteranymajorchange of geographical position, thescale shouldbenewlyadjusted
(calibrated) (Chapter 4.3).

2 Puttingthescaleintooperation
2.1 Remove the transport arrestment
• Removethe3screwsofthetransportarrestmentintheweighing-pan
supportandthe3plasticinsertsbetweentheweighing-pansupport
and the scale housing.
• Place the weighing pan on the scale.
2.2 Leveling the scale • Level the scale horizontally by turning the leveling screws. The air
bubble of the level indicator must lie within the black inner circle.
2.3 Power supply
The scale is normally powered by the built-in storage battery. The AC adapter is only used for charging
the storage battery. While the battery is being charged, the scale receives power from the power supply
network, so you can still work with the scale even if the battery needs recharging. Battery charging also
continueswhile thescaleisswitchedoff. The timerequiredforrechargingdepends on howlowthecharge
in the battery has become. However, to avoid overcharging the battery, do not leave the scale connected
to the power supply with the AC adapter for more than 24 hours.
Battery operation (AC adapter not connected)
Observe the red LED above the battery symbol Y:
LED is not lit: The battery is sufficiently charged.
LED flashes: The charge of the battery is almost exhausted. Connect
the AC adapter as soon as possible to recharge the battery.
Charging the battery/operating from the power supply
The connecting socket for the AC adapter is located underneath the
balance adjacent to the front-left leveling screw. Remove the rubber
plugandconnecttheACadaptertothescaleandtothepowersupply.
Observe the red LED above the battery symbol d:
LED flashes: The scale is receiving power from the power supply
network, the battery is being charged.
LED is continuously lit: The battery is fully charged, the AC adapter
can be disconnected again.

Thescalewasadjustedatthe factory. However, we still recommendadjusting the scalewhen itis put into
operation for the first time, and thereafter at regular intervals, especially after a change of location.
Adjustment can only be done in service mode (see chap.4.1). Before doing the adjustment, the geo
adjustment value must be checked for correctness in the “GEO” menu block (see table in Chapter 7).
• In service mode call up the “CAL” menu block. With the TARE key select “CAL YES” and then start the
adjustmentwith the ON/OFFkey.
• Selectthedesiredweight unit forthe adjustmentandconfirmwith
theON/OFF key. The units available dependon the selected region
(menu block “CTY”): for the setting “EU” (Europe) only “kg” is
availablewhile forthesetting“GE”(USA)there is achoicebetween
“kg” and “lb”.
• Select the maximum capacity of the scale (this is printed below
the display, adjacent to the level indicator) and confirm it with the
ON/OFF key. Note: The values in the display have a 1000x
higher resolution, i.e. a displayed value of 6000 represents 6 kg
or6 lb (dependingontheunitselectedpreviously)andadisplay-
ed value of 15000 represents 15 kg or 15 lb.
• The scale prompts you to empty the weighing pan. Remove any
loads on the pan and confirm this with the ON/OFF key. The scale
then performs a zero setting during which a counter is displayed
which counts backwards from 5 to 1.
• After the zero setting, your are prompted to place an adjustment
weightonthepanwhichcorrespondsto2/3oftheselected capa-
city(in thisexample4 kg/lb,correspondingto2/3ofthe weigh-
ing capacity of 6kg/lb). Confirm that the weight has been placed
onthepanwiththeON/OFFkey.Whiletheweightisbeing measur-
ed, a counter is again displayed which counts backwards from 5
to 1.
• The scale now prompts you to load the weighing pan with the
adjustmentweightwhichcorrespondstotheselectedcapacity(in
this example 6kg/lb). Confirm that you have placed the weight on
the pan by pressing the ON/OFF key. While the weight is being
measured, a counter is again displayed which counts backwards
from 5 to 1.
•The adjustment is complete. Press the ON/OFF key to save the
result and quit service mode. If you do not want to save the result,
pressTARE andconfirm the “Abort” messagewiththe ON/OFF key.

4.4 Monitoring the test substances
The metrology features of the balance and any possible available adjusting weight must be
checked at regular intervals within the scope of quality assurance. For this purpose, the
answerable user must define a suitable interval as well as the nature and scope of this check.
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. Test weights and
balancescan be adjusted quickly and at a reasonable price in KERN’s accredited DKD calibration
laboratory (return to national normal).
4.5 Verification
General:
AccordingtotheEUguideline90/384/EECbalancesmustbeverifiedofficiallyiftheyaretobeused
as follows (legally regulated area):
a) For commercial transactions if the price of goods is determined by weighing
b) For the production of medines in pharmacies as well as for analyses in the medical
and pharmaceutical laboratory
c) For official purposes
d) For the production of finished packages
In case of doubt, please contact your local office of weights and measures.
Verification information: (see chapter 9.3 Declaration of conformity)
AnEU qualificationapprovalisavailablefor those balancesmarkedasappropriatefor verification
in the technical data. In the event that the balance is applied in an area subject to verification as
described above, it must be officially verified and re-verified at regular intervals.
Re-verificationofabalanceiscarried out in compliance with the respectivelegal provisions ofthe
states. Theterm ofverificationvalidityforbalances inGermany,forexample,is normally2years.
The legal provisions of the country of use are to be observed.

5 Error messages
Display Cause and remedy
E11, E16, E18 Internal error (RAM/ROM/EEPROM). Contact dealer.
E48 Error in the scale configuration. Check all parameters in service mode.
ERROR Software error. Restart the scale with the ON/OFF key. If the error still occurs,
replace the storage battery (Chapter 8).
------ The weight value is unstable or zero setting is not possible. Check the environ-
mental conditions (drafts, vibrations, etc.). If necessary, change the filter set-
tings in the menu (menu block “S4”, see Chapter 4). Under certain conditions
there could also be a difference of air pressure between the scale housing and
the surroundings. Unscrew the rear leveling screws until the ventilation openings
under them are free. If water drains out, contact you dealer.
nnnnnn Overload (load exceeds weighing capacity by more than 9 display steps). Re-
move the load and set the display to zero with the akey. Readjust (cali-
brate) the scale if necessary.
WWWWWW When zero was set there was a weight on the scale. When the load is removed
this error message appears. Ensure that there is no weight on the pan and then
press the akey. If the error message occurs again, the scale must be ad-
justed (calibrated).
Note: If the setting “S11” = “Off” was selected in the menu (Chapter 4.2), when
zero-setting is done with a weight on the balance and the weight is then re-
moved, the negative weight value is displayed instead of this error message.
6 Cleaning the scale
•Disconnect the scale from the power supply before starting to clean!
• Use a soft cloth (no acids, alkalis, or strong solvents).
• Do not use abrasive cleaning agents: they can scratch the display.
• If badly soiled, remove the weighing pan and leveling screws, and clean them separately.
• Observecompany-internalandindustry-specificregulationsregardingcleaningintervalsandpermitted
cleaning agents.
