Terminating the
calibration
prematurely
When you want to terminate the calibration prematurely
after a calibration step is finished press the
g
key. The
instrument returns to the measuring mode. The instrument
stores the data calibrated up to this point and will use them
for future measurements.
7 Insert the 0.02 NTU/FNU calibration standard in the
cuvette shaft so that it clicks into place.
8 Press the
1
key and align the cuvette as
described on page 55.
After releasing the
1
key a 30 seconds
countdown is displayed. The instrument measures
the calibration standard and afterwards shortly
displays the 0.02. Then the instrument returns to the
measuring mode:
