Introduction
Congratulations on your purchase of Extech's 433201 (115V) or 433202 (220V)
Microprocessor Thermocouple Calibrator/Thermometer. A precision millivolt signal is
either input from a thermocouple (“Measure” mode”) or output to another thermocouple
device (“Calibrate” mode) and the corresponding temperature, according to standard
temperature tables, is displayed on the meter’s 4 digit LED display.
