6.9 Linearisation
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 equipment, you
can improve this by means of linearization.
• In balances with a resolution of > 15 000 dividing steps carrying out a
linearisation is recommended.
• 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 “Monitoring of test equipment”.
• Observe stable environmental conditions. Stabilisation requires a
certain warm-up time.
• After successful linearisation you will have to carry out calibration;
see chapter “Monitoring of test equipment”.

Confirm by , the password query „Pn“ will be displayed.
Press , , successively .
Ensure that there are no objects on the weighing pan.
Wait for stability display, then press .
When “Ld 1“ is displayed, put the first adjustment weight (1/3
max) carefully in the centre of the weighing platform. Wait for
stability display, then press .
When “Ld 2“ is displayed, put the second adjustment weight
(2/3 max) carefully in the centre of the weighing platform.
Wait for stability display, then press .
When “Ld 3“ is displayed, put the third adjustment weight
(max) carefully in the centre of the weighing platform. Wait
for stability display, then press .
After a successful linearisation the balance will carry out a
self-test. Remove adjustment weight during selftest, balance
will return into weighing mode automatically.
