Calibration
Calibration
Procedure
Display
Procedure
Display
1. In a clean atmosphere, press E
and C simultaneously and hold for
5 seconds. The detector beeps
four times. The detector then
beeps once more signifying that
calibration has started.
5. When the display flashes the gas
cylinder, connect the calibration
bottle and apply gas at a flow rate
of 500 to 1000 ml/min. (refer to the
next page). The detector beeps
three times at the end of the span
stage. Remove the calibration gas.
2. The display flashes AUTO-ZERO
while the detector automatically
zeroes the sensor. The detector
beeps twice at the end of the autozero stage.
6. Press E or D to change the next
calibration due date. Press C to
save.
3. If the detector is pass code
protected, PASS flashes on the
display. The correct pass code
must be entered before proceeding
to set span.
7. Press C to save the current alarm
setpoint. Press E or D to change
the alarm setpoint and press C to
save the new value. The detector
beeps and vibrates four times at
the end of calibration.
4. The display flashes the current
calibration gas setting. You can
press C to accept the current
setting, or you can press E or D
to change the setting and press C
to confirm your new selection.
a Warning
For correct flow and span rates, refer to your user
manual.

particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of
the following measures:
•
Reorient or relocate the receiving antenna.
•
Increase the separation between the equipment and
receiver.
