3. The detector enters the zero function.
zeroing displays while the detector
zeros all of the sensors.
If a sensor fails to zero, it cannot be
calibrated. Refer to Startup Self-Test
Troubleshooting in the
GasAlertQuattro Technical Reference
Guide.
If the IR Lock option is enabled, the
following screen displays to indicate
calibration can only be performed using
an IR device (MicroDock II or IR Link).
4. When the following screen displays,
attach the calibration cap and apply
calibration gas at a flow rate of
250-500 ml/min. Refer to Connecting the
Gas Cylinder to the Detector on page 9.
If a sensor is not yet due for calibration,
its box will have a greyed out

5. The detector initially tests for gas.
When a sufficient amount of gas is
detected, displays beside each gas
that is detected.
6. The detector then begins calibrating
the sensors. The following activities
occur during the span:
• calibrating displays at the bottom of
the screen.
• Gas values adjust during the span.
• Target gas values that are defined in
FleetManager II display above or
below the adjusting gas value.
To abort calibration after the sensors
have been zeroed, press C .
7. When the following screen displays,
close the valve on the gas cylinder and
remove the calibration cap from the
detector.
A check mark displays beside each
sensor that has calibrated successfully.
