Calibration and Setting Alarm Setpoints

Calibration Procedure

To calibrate the detector and set its alarm setpoints, perform

the following procedure.

Note

To quit at any point after the auto zero, press

C to

exit auto span. Then press F to exit setting

alarm setpoints. The detector retains any saved

values and the audible alarm beeps four times

before the detector returns to normal operation.

Start Calibration

1. Activate the detector (if applicable).

2. Press C and H simultaneously. The LCD displays

the following:

The audible alarm beeps once.

Auto Zero and Oxygen Sensor Calibration

3. The LCD displays flashes N while the

detector automatically zeroes the H

S, CO, and

LEL sensors and calibrates the O

sensor.

The audible alarm then beeps twice.

Auto Zero Sensor Fail

Note

Do not apply the calibration gas until the LCD

displays a flashing gas cylinder; otherwise, the auto

zero will fail.

If a sensor fails, the LCD displays Err (error) and

skips the span for the failed sensor(s). Press

C to

exit auto span. Then press F to exit setting

alarm setpoints. Then restart calibration in an

atmosphere that is clear of the targeted gases. If

the auto zero fails a second time, restart the

detector to test the sensors.
