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 PGM-65XX.
For a multi-sensor span calibration, a constant-flow regulator producing 0.75 to 1 liters per minute should
be used. Attach one end of a "T" using Teflon tubing to the filter on the PGM-65XX inlet. (You can use RAE
Systems P/N: W01-3003-000).
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 "T" tube and connect gas to the PGM-65XX.
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.
Single-Sensor Span Calibration
To perform span calibration of an individual sensor, follow these steps:
1. At the Calibration Menu, select "Single Sensor Span."
2. Select a sensor from the list.
3. Connect the "T" tube and connect it to a source of calibration gas.
4. Verify that the displayed calibration value meets the concentration label on the gas cylinder.
5. Start the flow of calibration gas.
