Prepare a calibration gas or similar to
create suitable reference conditions. See device documentation for calibration requirements
and recommendations (for example, the effect of existing adjustments and environmental
compensation settings).To adjust the CO2 measurement
of the probe that is connected to the transmitter:
Before starting the adjustment, make sure that your environmental compensation settings
(for example, the relative humidity and oxygen concentration values given as the current
operating environment) are correct for your present environment. You can review and change
the environmental settings in the Configure device menu.
To open the Insight PC software calibration menu, select to access
Insight main menu. In the main menu, select Calibrate.
Select CO₂ adjustment.
Insert the probe in the reference environment for the first calibration point.
Wait for the measurement to stabilize fully. The graph shows readings of the last 60
minutes.
When the measurement has stabilized, click the Reference value, point 1 text box and enter the CO2 level of calibration point 1. Press ENTER or click outside the text box when done.
Check that the measured value for point 1 is automatically inserted.
If you want to calibrate in more than one point, repeat the procedure for all desired
calibration points.
Check the difference between each reference and measured value. Very large differences
may be due to insufficient stabilization time or unsuitable calibration setup.
If you want to adjust the device, select Activate adjustment.
To exit without taking the adjustment in use, select Close.
After calibrating your device, update the information in the Calibration information tab.
