Performing External Linearization
After defining the linearization weights, the linearization procedure can be
started.
Note: If linearization weights of sufficient accuracy are available (at least one digit
greater than the display accuracy), it is not necessary to define the lineariza-
tion weights (in the INPUT mode).
In this case, you can start linearization by selecting the “
def. ext.lin.
” menu
item.
The procedure is described below.
– Activate the service mode again (see page 11).
– Press
q
.
– Press
v
(several times) to select the “
ext. linear
” menu item, tare the
balance if necessary and press
q
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/ad-
justment is performed automatically (code 1 10 1: calibrate, then auto-ad-
just), or the deviation from the last calibration is displayed, but no adjust-
ment 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
q
to make the corre-
sponding adjustment, or press
c
to cancel the adjustment procedure.
– The second linearity weight is displayed.
– Center the corresponding weight on the weighing pan and press
q
to
confirm.
– Repeat this procedure until all linearity weights have been adjusted.
– After concluding the linearization routine, the service mode remains active
until you press
c
.
Note: Always perform internal or external span adjustment after external lineariza-
tion.
