16.3 Two-Point Calibration
This Synergy Controller application note describes the gain (span) and offset calculations for a two point
calibration.
Specifically, when two reference values are known, and compared against the Synergy controller readings,
the calculations in this spreadsheet can be used to correct the errors at these points. The two reference
points and the two controller points represent two lines in the graph below.
Open Excel and load the file for this application note:

1 Note the current Gain (Span) and Offset values for the input then set the Gain to 100% and the offset to 0.
2 Fill in the Synergy Controller and Reference Values (from Calibrator) in the Yellow boxes below for the two calibration points
3 Read the new Gain and Offset in green on the right and enter them for the input.
Corrected values show the value expected after the new gain and offset are entered.

Note:
Gain values under 98% or over 102% percent may indicate an issue with the sensor, the setup, or the controller.
Consult Tidal Engineering if values outside this range are calculated by the spreadsheet.
