Sampling Data Logger User Manual
To ensure maximum accuracy, it is recommended to install the device in an environment that will
routinely see this low value. Alternatively, the unit can be exposed to fresh air for a few minutes
periodically, or set the ABC period to 0 sec. to perform a calibration as specified in the next section.
Calibration
The calibration process varies depending on the type of unit and whether it has optional data logging
functionality or not. All units are factory‐calibrated with multiple reference points of gas, and have been
verified to be accurate within their specific functionality before shipment. However, if the unit is
severely jolted or otherwise mechanically disturbed, the sensor can drift requiring recalibration. All
calibration procedures follow a single‐point calibration routine that effectively shifts the zero‐point of
the CO2 sensor.
Attach calibration gas to the unit and connect it to a personal computer. Open the calibration screen in
the GasLab® software. Click the "Calibrate" button in the calibration tab for the desired gas, located in
the "Configure Sensor" screen. As long as the gas concentration is stable, the unit should instantly
reflect the calibrated value. This can be confirmed by watching the display. To see the calibration value
in real time, click in the "Collect Real time" button to capture these values before opening the
configuration screen.
0‐1% or 0‐30% Sampling Unit with Data Logging
Calibration can be performed using either 0% CO2 calibration gas (typically nitrogen, argon, etc.), or
using a fresh source of air, assumed to be approximately 400ppm.
Open the calibration screen in the GasLab® software. Click the "Calibrate" button in the calibration tab,
located in the "Configure Sensor" screen.
