6. Press "OK" to proceed to the PID sensor test. Turn on the gas and press Start ([Y/+] button).
While the bump test is being performed, PID sensor readings are shown. Once the bump test
completes, pass/fail test results and readings are shown for the PID sensor.
Note: If other installed sensors require a dedicated cylinder of gas to calibrate, the instrument
prompts for calibrating these sensors at this point.
If one or more sensors fails a bump test, be sure to calibrate those sensors.
7. The bump test is now complete. Press Exit to return to the main measurement screen.
8. Now perform a manual alarms test.
If all the alarms and all sensors have passed and no sensor is due for a calibration, the instrument is now
ready for use.
Note: When a manual bump test is performed, the readings shown are in the equivalent units of the
calibration gas, and not the measurement gas (if different).
Zero Calibration
The instrument should be zero calibrated in clean ambient air with 20.9% oxygen. A zero calibration
should precede a span calibration.
IMPORTANT! The parts-per-billion PID sensor for volatile organic compounds (VOCs) should not be
zeroed in fresh air. VOCs are normally present in ambient air, so zeroing the sensor in ambient air will
not allow for a true zero to be set. The parts-per-billion PID sensor should be zeroed with ambient air
using a charcoal filter or a VOC zeroing tube.
Fresh Air Calibration
This procedure determines zero points of most sensors. The PGM-65XX should be zero-calibrated in clean
air with 20.9% oxygen or with a cylinder of clean zero air.
At the Calibration menu, select "Fresh Air" by pressing [Y/+] once to enter fresh air calibration.
After a timer countdown, the zero calibration is done. The LCD displays the sensor names and tells you
whether each calibration passed or failed, followed by the sensor readings.
Note: You can abort the calibration at any time during the countdown by pressing [N/-].
