1. INTRODUCTION
Congratulations on your purchase of Extech's 433201 (115V) or 433202 (220V)
Microprocessor Thermocouple Calibrator/Thermometer. This calibrator has been
designed with special cold junction compensation circuitry and a complex precision
resistor network to facilitate the calibration of other thermocouple devices. They also
provide a precision millivolt output which simulates temperature values as shown on the
LCD display. The unique "flip-up" cover adjusts for best viewing angle and the meter
automatically shuts off when the cover is closed. 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.
