P11/ P17
Step 4:
To adjust the physical zero
point:
Apply zero gas to the analyzer.
Connect the DVM to the follo-
wing 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 conguration is a result of
"try and error"!
Change resistor and/or position
until the voltage is 0 V ± 500 mV.
Finally solder in the resistor
between P11/ P17.
