
The TC (Thermocouple) minijack is used for thermocouple simulation during thermometer
calibration, and thermocouple measurements. You must use the correct thermocouple wire and plug
when using this connector. For example, if simulating a type K thermocouple, use type K
thermocouple wire and type K plug for making connections

The 20A terminal is the source of current output when the 20 A range is selected (3 A - 20 A)

The AUX (Auxiliary Output) terminals are used for ac and dc current outputs, the second voltage
output in dual voltage modes, and ohms sense for 2-wire and 4-wire compensated resistance and
capacitance measurements, and RTD simulation

The GUARD terminal is always connected internally to the internal guard shield. This shield is tied to
the NORMAL LO signal ground inside the Calibrator unless the
B
key is pressed so that its
indicator is lit

The NORMAL (Normal Output) terminals are used for ac and dc voltage, ohms and capacitance
sourcing, and Resistance Temperature Detector (RTD) simulation.
