To adjust the physical zero you need
to measure some voltages on the XSP
board:
Depending on which channel the cell is
assigned to, the measuring signal (+)
can be measured at pin 3 of the related
connector. GND (-) is available at a se-
parate pin (see figure).
The measured voltage should be
0 V ± 50 mV.
The cell contains strong ma-
gnets!
Use only non-magnetic tools to
adjust the zero point!
Step 1:
The figure to the left shows a heated
paramagnetic oxygen cell.
Note!
Depending on your specific instrument
alternatively an unheated cell may be
installed.
In this case skip step 2 and continue
with step 3.
Step 2:
Open the cell cover by loosening the
screw S1 at the top.
