2.4 Output Goes Negative
If during operation of the instrument, gas pressure exceeds 20 psig, the
output of the sensor may reverse polarity, readings on the display may go
negative. If this happens:
Make sure analyzer is mounted in the upright position (see
chapter 3, Installation).
Turn power off by unplugging the instrument.
Turn gas pressure to less than 20 psig.
Turn power on again.
Return instrument to analyze mode.
