Adjustment
To make a 2-point adjustment, you need a low reference and a high reference (select
references that are near the low and high ends of your measurement range). Prepare the
calibration references (for example, reference gases with known concentrations) before
starting the adjustment.
Check the possible probe-specifc adjustment limits and requirements for 2-point
calibration (for example, the minimum
dierence between the low and high reference
points) from the probe's documentation.
To make a 2-point adjustment (GMP252 ppmCO
2
example):
1. Connect to the wireless configuration interface and open the Calibration menu.
