Performing External Linearization
After defining the linearization weights, the linearization procedure can be
started.
– Activate the service mode again (see page 11).
– Press F6 F6 F6 F6 F6 to activate the adjustment menu.
– Press F1 F1 F1 F1 F1 to activate the “
ext. linear user wt.
” menu item, or tare the
balance and press F6 F6 F6 F6 F6 to start the linearization routine.
– The first linearity weight is displayed.
Center the corresponding weight on the weighing pan.
Note: Depending on the menu code setting (under 1 10 X), either calibration/
adjustment is performed automatically (code 1 10 1: calibrate, then auto-
adjust), or the deviation from the last linearization is displayed, but no
adjustment is made until you press a key (code 1 10 2: calibrate, then
manual adjust).
– The deviation from the last adjustment is displayed.
– If the error exceeds the tolerance limits, either press F6
F6 F6 F6 F6 to make the corre-
sponding adjustment, or press F1 F1 F1 F1 F1 to cancel the adjustment procedure.
– The second linearity weight is displayed.
– Center the corresponding weight on the weighing pan and press F6
F6 F6 F6 F6 to
confirm.
– Repeat this procedure until all linearity weights have been adjusted.
– After defining the last linearization weight, all adjustment weights must be
removed from the weighing pan and the balance zeroed again.
– After concluding the linearization routine, the service mode remains active
until you press c .
If linearization weights of sufficient accuracy are available (at least one digit
greater than the display accuracy) it is not necessary to defined the lineariza-
tion weights before performing the adjustment routine (in INPUT mode).
In this case, linearization can be started immediately by selecting the menu
item
