Dew Point Temperature Mode - Extech Instruments VIR50-NISTL User Manual

IR-only mode
In the IR-only Mode the meter can measure IR temperature, air temperature, air humidity, dew-point
temperature, and wet bulb temperature but without the video camera capabilities. The IR Maximum
(MAX) Temperature, IR Minimum (MIN) Temperature, IR Differential (DIF) Temperature, and the IR
Average (AVG) Temperature can also be displayed. Press and hold trigger to measure the
temperature.

Dew Point Temperature Mode

In the Dew Point mode the meter displays the Dew Point temperature measurement along with the
IR temperature value. Press and hold the measurement trigger to take a measurement.
In the Dew Point mode the percentage bargraph
indicates how close the IR temperature is to the Dew
Point temperature. At 100%, the two values are identical.
