3.0 User Re-Calibrate
This menu option accesses the controls used for re-calibration of the TIO0110 module using local standards.
This calibration requires a highly accurate DMM, a stable, programmable DC voltage source and a standard type
TT thermocouple probe in a stable ice bath. Required equipment is as follows:
DMM Fluke 8508A, HP3458A or equivalent
DC Voltage Source EDC 52X or equivalent
Thermocouple Omega TRCIII ice point with TRP-T thermocouple probe or equivalent
Each selection on the TC Setup screen enables a mode to measure and capture calibration data. The values are
stored in non-volatile memory in the sensor module. Refer to the MFT TIO0110 Calibration Manual for details of
the re-calibration process.
