P11/ P17
Step 4:
To adjust the physical zero point:
Apply zero gas to the analyzer.
Connect the DVM to the following
pins:
P4.5 Raw signal (+)
P4.15 Bridge voltage (-); GND
CAUTION!
Do not short-circuit pins!
To adjust the physical zero point, it is
necessary to install a resistor between
P11/ P17 at position 1, 2, 3 or 4 (the
following gure shows it at position 4).
The position and value depends on
the individual cell parameters. Proper
conguration is a result of "try and er-
ror"!
Change resistor and/or position until
the voltage is 0 V ± 500 mV.
Finally solder in the resi-
stor between P11/ P17.
