Single Sensor Zero
This allows you to perform zero calibration on individual sensors. Even though most toxic gas
sensors can be zeroed in fresh air, sensors such as the CO
volatile organic compounds (VOCs) should not be zeroed in fresh air. Both CO
are normally present in ambient air, so zeroing these sensors in ambient air will not allow for a
true zero to be set for such sensors. The CO
the parts-per-billion PID sensor with ambient air using a charcoal filter or a VOC zeroing tube.
Note: If an oxygen sensor must be calibrated in nitrogen, then use this Single Sensor Zero.
1.
If you are using a charcoal filter, connect it to the instrument.
2.
If you are using dry air, install the calibration adapter and connect it to a source of dry
air.
3.
At the Calibration Menu, select "Single Sensor Zero." Press [Y/+] once to enter the zero
calibration sub-menu.
4.
Start the flow of dry air, if used.
5.
Press [Y/+] to start zero calibration.
6.
A countdown screen appears. You can abort the calibration at any time during the
countdown by pressing [N/-].
Note: Dotted line indicates automatic progression.
7.
If the calibration is not aborted, the display shows the sensor names and tells you
whether the zero calibration passed or failed, followed by the sensors' zero calibration
readings.
