Calibration and Setting Alarm Setpoints
Calibration Procedure
To calibrate the detector and set its alarm setpoints, perform
the following:
Start Calibration
Note: To quit at any point after auto zero, press
A
. The
detector retains any saved values, and the audible alarm
beeps 4 times before the detector returns to normal
operation.
Note: At any point after auto zero but before calibration gas
is detected, press
C
to bypass calibration and proceed to
alarm setpoints.
Note: Verify that the calibration gas you are using matches
the span concentration value(s) in the detector. See the
section “ Set Span Concentration Values ”.
1. In a clean atmosphere, press
C
and
H
simultaneously
and hold for 5 seconds. The detector beeps 4 times and
the display shows:
The audible alarm then beeps once signifying that calibration
has begun.
Auto Zero and Oxygen Sensor Calibration
The display flashes
N
while the detector automatically
zeroes the toxic sensors and calibrates the Oxygen sensor.
Auto Zero Sensor Fail
The audible alarm then beeps twice.
Note: Do not apply the calibration gas until the display
shows
K
; otherwise, the auto zero step will fail.
