Multi-Sensor Span Calibration
This lets you perform a span calibration on multiple sensors simultaneously. It requires using
the appropriate span gas and that the concentration labeled on the gas cylinder matches the
concentration programmed in the MultiRAE.
For a multi-sensor span calibration, a constant-flow regulator producing 0.5 to 1 liters per
minute should be used, and the calibration adapter must be installed on the instrument.
Testing and calibration with an AutoRAE 2 must be performed using demand-flow regulators. A
calibration adapter must not be used. Teflon tubing must be used to test or calibrate the PID
sensor. Follow the steps described here to perform a multi-sensor span calibration:
1. Attach the calibration adapter and connect gas to the MultiRAE.
2. Start the flow of gas and then either press [Y/+] to begin calibration or wait for
calibration to start automatically once the sensor “senses” the gas. A countdown screen
is shown. You can abort the calibration at any time during the countdown by pressing
[N/-].
If the calibration reaches its conclusion, it shows the sensor names and tells you whether the
calibration passed or failed, followed by the sensor readings.
Note: If there are other sensors to be calibrated at this stage, the screens will guide you through
the process.
