The TIO0110 is a thermocouple (T/C) measurement and simulation module for use with the Meriam MFT 4000 Series Multi-Function Tester. The module will accurately measure or source ±110 milli-Volts (mV) for any of twelve (12) different T/C types according to NIST 175, ITS-90 (default) or ITS-68 standards. In the measure mode, the TIO0110 module converts mV dc to a temperature value in the user-selected temperature unit (°F, °C, °R or °K) and per the selected standard. Milli-volts can also be displayed for direct reading or trouble shooting needs.

In the simulate mode, the TIO0110 module simulates an accurate mV signal to a receiving device. Users can enter the precise simulation temperature value, change the value with ramping controls on the MFT, or set-up and select from three Auto-step test procedures per T/C type. Test points are determined by the user and can be stepped through automatically or manually as desired. See T/C Table 1 on page 2 for available T/C types and measurement / simulation accuracy.

T/C calibration coefficients are factory loaded into module memory for instant access by the base MFT. Field recalibration of the module is provided by the MFT's "Rcal" feature.
