Model CAL10 Thermocouple Calibrator

Measures Thermocouples, Voltage and Current, Programmable

Calibrate electronic process instruments such as controllers, transmitters, transducers or recorders with Model CAL10 Thermocouple Calibrator. Model CAL10 is designed to independently measure and simulate dc mV or V and common thermocouple signals (Type J, K, T, E, J (DIN), and T (DIN) or measure current.

Programmable functions, such as square root extraction for flow signals, ramp/step increment value, selectable engineering units, isolated signal conversion or automatic changing of the output value simplify many calibration tasks. Calibration values can be stored and recalled using the Low, Mid, or High keys. Cold junction compensation can be selected for automatic or manual. Program the automatic shut-off to conserve battery life.

The Model CAL10 calibrator features 500 VDC input/output isolation and reverse polarity protection. The unit includes three 9V batteries, two sets of dual test leads, a dual binding post adapter, carrying case, and instruction manual.
