6.6 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.

6.7 Linearisation

(only models PCB 250-3, PCB 350-3, PCB 2500-2, , PCB 3500-2,)
Linearity shows the greatest deviation of a weight display on the scale to the value of
the respective test weight according to plus and minus over the entire weighing
range.
If linearity deviation is discovered during a monitoring of test resources, you can
improve this by means of linearization.
• Carrying out linearization is restricted to specialist staff possessing
well acquainted with the workings of weighing scales.
• The test weights to be used must be adapted to the weighing scale's
specifications; see chapter 3.4 "Testing instruments control".
• Observe stable environmental conditions. Stabilisation requires a
certain warm-up time.
• After successful linearization you will have to carry out calibration;
see chapter 3.4 "Testing instruments control"
