NOTE: SEM four-electrode CO sensor (Hydrogen interference adjustment). There
is a hydrogen cross-interference adjustment for the four-electrode carbon
monoxide sensor. This calibration, intended to remove the interference of
hydrogen from CO measurements, should be rarely done, typically if the sensor is
being replaced.
To null the hydrogen interference, feed hydrogen gas, typically 100 - 1000 PPM,
and follow the same procedure as for the other span gas calibrations.
4. Printer-Paper replacement
The printer uses a high quality 2" thermal paper. Keep any spare paper rolls in a
cool dark place to prevent paper discoloration.
To replace the thermal paper:
a. Unfasten the two screws that secure the top cover of the printer.
b. Unroll approximately 6 inches of a new roll of thermal paper.
c. Cut the end of the paper square with scissors.
d. Orient the roll so that the paper unrolls from the bottom of the roll.
e. Locate the slot immediately beneath the printer and insert the paper end as far
as it will go.
f. Use the feed wheel on the
side of the printer
mechanism to advance the
paper.
g. When the paper appears
exiting the printer, feed it
through the slot in the top
of the unit.
h. Replace the roll on the
spindle and replace the
cover.
