Calibration - Offsets
Adjust the sensor readings to match a known standard(s).
Current Reading (uncorrected) = raw sensor reading with no offset applied.
Offset = Value that will be added to the Current Reading (uncorrected). The
adjusted reading (uncorrected + offset) is the value reported on all screens
outside of the Sensor Calibration screen.
1. To adjust the calibration offset, touch Offset field of the desired sensor. A pop-up
will display, which allows an offset value to be adjusted for the sensor.
2. Using a known standard as reference, change the offset to match the value
reported by the standard. For example, if the Sump / Water Temp reports an
uncorrected reading of 35
o
C, and the standard reference reports 36
o
C, change
the offset to +1
o
C.
When the Offset value is changed, the current date will be saved as the Last
Cal. Date
Offset limits:
Temperature = +/- 5
o
C
Conductivity = +/- 100 µS
Fill Level = +/- 5%
