2 Installation of the balance
2.1 Unpacking and package volume
Remove the balance from the packing materials carefully, take off the plastic cover and set
up the balance at the work site.
Keep all packing materials for future transport of the balance.
Standard accessories:
KERN VC
• Balance
• Weighing plate
• Power cord
• Instruction manual
2.2 Installation
• Put the weighing plate on the balance such that the holes match the pins on the
weighing plate.
• Set the balance on a stable surface.
• Make sure the balance is level by adjusting the foot screws until the air bubble
(at the left front of the body) is inside the circle.
3 Power supply
3.1 Power connection
Connect the adapter cord to the bottom of the balance.
Before plugging the cord into the socket, make sure that the voltage setting on the balance
is the same as the mains voltage.
3.2 Battery operation
Remove the battery cover at the bottom of the balance. Insert six (6) 1.5V batteries (size
D). Replace the battery cover.
If the balance will not be used for an extended period of time, remove the batteries and
store them separately. Battery acid leaks could damage the balance.

5 Adjustments
The adjustment weights can be used to check and adjust balance precision at any time.
Adjustment weights can be acquired from KERN as an optional component. To decide
which adjustment weights are required, refer to Chapter 1 “Technical Data“.
5.1 Requirements:
Note! In calibrated apparatus, the adjustment switch can only be accessed by
destroying the safety seal. This would void the calibration.
• The adjustment switch is
located next to the screw
of the right front foot,
below the balance.
• Press with a long, blunt
object (e.g., tip of a
ballpoint pen) inside the
threaded hole.
• Turn the adjustment
switch on; the balance is
ready to be adjusted.
