6.3 Optical balance adjustment
When the sample cell is reassembled after having been detached for cleaning or the like, this
optical zero adjustment should be performed before use.
When this mode is assumed, the input signal from the measurement detector is displayed on
the main indicator while the input signal from the interference compensating detector is
displayed on the sub indicator.
The numerics vary in a range of -999 to 3200.
This adjustment is made so that the readings on both indicators approach zero. Refer to
section 7.2.3 “Optical zero adjustment method” for details.
With the “
” indication flashing, press the CAL key
and the input signal from the measurement detector will
appear on the main indicator while the input signal from
the interference compensating detector will appear on the
sub indicator.
Press the CAL key after the optical balance adjustment.
A mistake in this adjustment will cause problems in measurement.
