These keys increase / decrease the analog
output by 100, 10 or 1 counts. Continue
adjustments until the voltage measured at the
output of the analyzer and/or the input of the
recording device matches the value in the upper
right hand corner of the display to the tolerance
The concentration display will not change. Only
the voltage reading of your voltmeter will change.

6.7.3.4. Analog Output Offset Adjustment

Some analog signal recorders require that the zero signal is significantly different from the
baseline of the recorder in order to record slightly negative readings from noise around the
zero point. This can be achieved in the M200E by defining a zero offset, a small voltage
(e.g., 10% of span), which can be added to the signal of individual output channels by
pressing SETUP-MORE-DIAG-ENTR-NEXT-NEXT and the following keys:
