Carefully read this operation manual before setup and commission-
ing, even if you are already familiar with KERN balances.
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 wind screen, the weighing plate, power
supply unit etc. against shifting and damage.
Balance, see chap. 3.1
Mains adapter
Operating instructions
Protective hood
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 da-
mage.
Ensure that the power unit does not come into contact with liquids.
Ensure access to mains plug at all times.
ATTENTION
The rechargeable battery and the battery match with each
other. Only use the delivered mains adapter.
Do not use the balance during the loading process.
The rechargeable battery can only be replaced by the same
or by a type recommended by the manufacturer.
The rechargeable battery is not protected against all environmental in-
fluences. If the rechargeable battery is exposed to certain environmen-
tal influences, it may set on fire or explode. Persons may be injured or
material damage may occur.
Protect the rechargeable battery against fire and heat.
Do not bring the rechargeable battery in contact with fluids,
chemical substances or salt.
Do not expose the rechargeable battery to high pressure or
microwaves.
Under no circumstances the rechargeable batteries and the
charging unit may be modified or manipulated.
Do not use a defective, damaged or deformed rechargeable
battery.
Do not connect or short-circuit the electrical contacts of the
rechargeable battery with metallic objects.
Liquid may squirt out from a damaged rechargeable battery. If
the liquid gets into contact with the skin or the eyes, the skin
and the eyes may be irritated.
Ensure the correct polarity when inserting or changing the recharge-
able battery (see instructions in the battery compartment)
The rechargeable battery operation is overridden when the mains
adapter is connected. For weighing in mains operation > 48 hrs. the
rechargeable batteries must be removed! (Danger of overheating).
If the rechargeable battery starts to smell, being hot, changing
the colour or being deformed, it must be immediately unplug-
ged from mains supply and from the balance if possible.
Carry out adjustment as near as possible to the balance’s maximum weight
(recommended adjustment weight see chap. 1). Weights of different nominal
values or tolerance classes may be used for adjustment but are not optimal
for technical measuring. The accuracy of the adjustment weight must corres-
pond approximately to or, if possible, be better than, the readability [d] of the
balance. Info about test weights can be found on the Internet at:
http://www.kern-sohn.com
Observe stable environmental conditions. A warm up time (see chapter 1) is
required for stabilization.
Ensure that there are no objects on the weighing plate.
Avoid vibration and air flow.
Always carry out adjustment with the standard weighing plate in place.
Press and hold the TARE and ON/OFF buttons simultane-
ously to enter the setup menu.
Wait until the first menu item < Cal> is displayed.
Confirm by button, < CalExt> will be displayed.
Confirm by pressing the button, the first selectable ad-
justment weight is displayed.
Use the navigation keys  to select the desired adjust-
ment weight, see chap. 1 „Adjustment points“ or „Recom-
mended adjustment weight“
Prepare the required adjustment weight.
Acknowledge selection by button.< Zero >, < Pt ld
> followed by the weight value of the adjustment weight to
be placed will be displayed.
Place the adjustment weight and confirm with button,
< wait> followed by < reMvld> will be displayed.
Once < reMvld> is displayed, remove the adjustment
weight.
After successful adjustment the balance automatically re-
turns to weighing mode.
In case of an adjustment error (e.g. objects on the weighing
plate) the display will show the error message < wrong
>. Switch off balance and repeat the adjustment process.
Press and hold the TARE and ON/OFF buttons simultane-
ously to enter the setup menu.
Wait until the first menu item < Cal > is displayed.
Confirm by button, < CalExt> will be displayed.
Use the navigation keys to select < caleud>.
Acknowledge by button. The numeric input window for
the weight value of the adjustment weight appears. The ac-
tive digit is flashing.
Provide adjustment weight.
Enter weight value, numerical input see chap. 3.2.2
