9.7.1 BLANK SETTINGS
The next area, is dedicated to the blank channel. Blank is a specific fluid sample required as a reference
sample for the spectra analytic measurement.
The STAC2 will then calculate each sample analytic chemical substances, against the Blank fluid.
The Blank fluid is considered as a neutral sample containing a level of 0 for each chemical analytic
parameters.
Set the frequency measurement. This is a
multiple of main cycle process measurement
defined in general configuration.
Ex:
10min main cycle and frequency of 2 result in a
sample measurement every 20 min
Each channel are independent.
Blank fluid is automatically measured one time
during first cycle process after starting STAC2 in
running process. Then next Blank measurement
will occurred according to frequency parameter.
Total tube length
for the related
channel in meter.
Pump suking
duration will be
automatically
adjusted
according tube
length outside
the STAC2 for
blank channel.
Consequently,
blank fluid
automatically
reach the flow
cell correctly.
