If performing a lab calibration, insert the sensor into the appropriate calibration meter and set to full scale
range of the sensor. If performing an environmental calibration, insert sensor into its targeted environment
at conditions of at least 10% of full scale range. For example a 120’ water level sensor should be calibrated
at a water depth of at least 12’. Calibrating at greater percentages (up to 100%) provides greater accuracy.
Enter the maximum unit range of the
sensor (
120
for a 120’ level sensor in
this example) in the
highest value
text
field and click the
Next
button.
Change the
Sensor Type or EU
(engineering units) field to the unit type you are calibrating to (i.e. meters,
feet, etc.) by clicking in the field and typing the unit name. Note that the
Sensor Type or EU
field is only a
text label. Actual readings are determined by the following calibration steps.
In case you make a mistake during the calibration process, write down the existing values in the
High Raw
and
Low Raw
fields before continuing (in this case
64435
and
12704
). Click the
Calibrate
button.
