WARNING
!
This quick reference guide is not a substitute for the operator's
manual. Read and understand the operator's manual before
using this monitor.
Parts
Powering on/powering off
To turn the monitor on, press the Mode button once.
To turn the monitor off, press and hold the Mode button until
"Release MODE to shut down" is displayed.
Perform a calibration check (either manually or with the IQ6
dock) before using the monitor.
Auto Calibration
Auto Calibration consists of two steps: zero calibration and span
calibration. To enter Auto Calibration mode, press the Mode
button three times rapidly (within two seconds). The monitor will
begin a five second countdown.
Press the Mode button again during this countdown to begin the
zero calibration.
NOTE
!
If the monitor is equipped with an IR-CO
cylinder of any CO -free mixture (e.g., N
2
be connected to the monitor before beginning the zero
calibration.
After the zero calibration is complete, the monitor will begin
another five second countdown.
Press the Mode button during this countdown to begin the span
calibration. The monitor will display a prompt for the appropriate
calibration gas to be applied (using the adaptor as illustrated
below).
When the sensor has been adjusted, the monitor will display a
prompt for the next gas to be applied.
When no further span calibrations are needed, the monitor will
shut down.
Auto Calibration Failures

The zero calibration will fail during the zeroing process if one or
more of the sensors reaches ±50% of the default alarm setpoint
(e.g., for LEL, a reading of 5 or higher, or -5 or lower). If this
happens, a forced fresh air calibration must be performed.
To begin the calibration, press the Mode button three times
rapidly (within two seconds). The monitor will begin a five
second countdown. During this countdown, press and hold the
Down Arrow navigation key. While holding the Down Arrow key,
press and release the Mode button. Continue holding the Down
Arrow key until the monitor begins beeping rapidly. If the zero
calibration still fails, one or more of the sensors may require
replacement.
Span calibration failure
WARNING
!
When detecting reactive toxic gases, dedicate a regulator for
each gas. Do not use regulators that have been exposed to
H S and then used with chlorine.
2
Span calibrations failures have three common causes: the
calibration was attempted with an expired calibration gas,
incorrect calibration materials were used, or one or more of the
sensors require replacement.
