SYSTEM ACCURACY WITH GQS-TC1 THERMOCOUPLE INTERFACE Table I System Accuracy (reading in temperature units): Includes the HHC base unit and GQS-TC1 interface module. (Does not include inaccuracy of the thermocouple device. Consult thermocouple manufacturer or ISA MC96.1 for thermocouple accuracy specifications. Typical inaccuracies range from ±1 to ±2.2°C.

APPENDIX E Certification of the TC1 Thermocouple Interface Module Theory With the TC1 module installed in the base unit (set-up to display in mV), a precision millivolt calibrator/supply will apply a known mV signal to the module/base unit system (simulating the Seebeck voltage) in place of a thermocouple. The applied mV signal can then be read on the base unit display and compared to the nominal input provided by the precision millivolt calibrator/supply. The TC1 module cannot be adjusted.
