6.2 Unpacking
Carefully remove the balance from its packaging, remove the plastic wrapping and position the balance in its
intended working location.
6.2.1 Installation
Install the balance in such a fashion that the weighing plate is absolutely horizontally.
6.3 Mains supply
Electric power supply is by means of the external mains supply circuit. The printed voltage level must comply
with the local voltage.
Only use original KERN mains supply circuits. The use of other makes is subject to approval by Kern.
6.4 Connecting peripheral equipment
The balance must be disconnected from the mains before connecting or disconnecting additional equipment
(printer, PC) to or from the data interface.
Only use KERN accessories and peripheral equipment with your balance. These have been ideally coordina-
ted to your balance.
6.5 Initial start-up
A warm-up time of 2 hours stabilises the measured values after switching on.
The accuracy of the balance depends on the local acceleration of the fall.
Please be sure to observe the information in the chapter on adjusting.
6.6 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 during the initial start-up, after change in location and
variation of surrounding temperature. It is also recommendable to adjust the balance periodically during
weighing operation in order to obtain exact measured values.
6.7 Adjusting (go to 7.2.6)
Using a precision weight, the accuracy of the balance can be checked at any time and adjusted.
Warning:
With verified balances, this precision adjustment is not possible
Adjustment procedure:
Check that the surrounding conditions are stable.
A short warm-up time of about 15 minutes is recommended for stabilisation.
