Introduction
Congratulations on your purchase of the Extech 433201A (115V) or 433202A (220V)
Microprocessor Thermocouple Calibrator/Thermometer.
In the ‘Measurement’ mode, a millivolt (mV) signal is accepted from a thermocouple and is
displayed on the 4-digit LCD display. A built-in temperature offset feature can be used to
compensate for variations found in standard thermocouples. By adjusting the offset, measurement
accuracy for a particular thermocouple can be optimized for a particular temperature.
In the ‘Source’ mode, a millivolt signal is output to an external device with the corresponding
temperature (according to standard temperature tables) displayed on the LCD display. Preset
temperature settings (source mode only) according to thermocouple type are stored in five memory
locations for easy recall.
If desired, the meter can be switched to the mV mode where Measurement and Source values
can be displayed in millivolts rather than temperature.
Careful use of this device will provide years of reliable service.
