See this file for information on calibrating and/or adjusting the sensors on the 2456 Piston Gauge Monitor. Note that WinPrompt is used to interface with the PG Monitor. Also note that all, or most, of these instructions are in the WinPrompt user manual and/or the product's user manual.
This document also applies to the 2465 Autofloat Controller but it has some additional parameters of Control Coefficients that the PG Monitor does not have.
2456 PG Monitor and 2465 Autofloat Controller - Calibration and Status Window Information
If you have the hardware to calibrate the 2455-11-006 RTD that is used with the PG Monitor but don't have software to calculate new coefficients, our TableWare software can be used to calculate new Rptw and a(10) coefficients.
