Calibration
If the sensor’s output is too low to be usable, then the message “Bad
Calibration Sensor End of Life, Entry Not Saved” will appear. The sen-
sor will now be marked as being
BAD
in the DIAGNOSTICS screen.
NOTE:
H

calibration can be bypassed by pressing the
ESC
button, after which the CALIBRATION LIST screen is re-dis-
played. Skip to Step 10 if the
ESC
button was pressed.

cylinder.
7. Attach a combination 1,000 ppm CO and
1,000 ppm H
2
cylinder to the regula-
tor of the calibration fixture, and then
use the
and buttons to enter an
Applied value that exactly equals the CO
concentration stamped on the cylinder.
8. Adjust the regulator for a flowmeter indica-
tion of approximately 2 SCFH, and then
press
ENT
to display the CALIBRATE H
2
screen.
The calibration range is from 400 to 1,500 ppm. An attempt to cali-
brate outside this range will cause the message “Bad Calibration
Wrong CAL Entry” to appear in the following
step.
9. Wait until the Measured reading stabilizes
(approximately 3 minutes), and then press
ENT
to calibrate the H
2
Measured value to
that of the Applied value; after which the mes-
sage “Good Calibration” should briefly appear
followed by the CALIBRATION LIST screen
being re-displayed.
If the sensor’s output is low, but still usable,
then the message “Good Calibration WARNING Low Sensor”
will appear. The sensor will now be marked as being
Low
in the
DIAGNOSTICS screen.
If the sensor’s output is too low to be usable, then the message
“Bad Calibration Sensor End of Life” will appear followed by the
CALIBRATION LIST screen being re-displayed. The sensor will now
