Warranty

Warranty claims shall be voided in case

• The appliance is used outside the described uses
• The appliance is modified or opened

• When working with the crane and suspended balance wear personal safety
equipment (helmet, safety shoes etc.).
2.9

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) fast and at moderate cost.

2.10 Testing upon acceptance

Inspect packaging immediately upon receipt and inspect device when unpacking, see
chap. 4.1. in the event of any evident damage.

2.11 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.
For checking original dimensions, s. chap. 4.3

2.12 Shutdown and storage

• Remove suspended balance from crane and remove all attachment devices from
the suspended balance.
• Do not store suspended balance outdoors.
