Infrared Temperature Probe Introduction
The Infrared Temperature Probe is a noncontact temperature measurement
accessory for use with a test instrument capable of measuring DC volts in the
millivolt range (200mV/400mV/600mV/2V/4V/6V range). The probe has a
temperature range of -30°C to 550°C (-22°F to 1022°F), with a basic accuracy
of 2% of reading, and an output of 1 mV dc per °C or °F.
Temperature is measured by pointing the probe at the surface to be measured,
and reading the temperature on the test instrument display.
Compatibility
The probe is compatible with all DC millivolt measuring instruments or this
automotive meter. Infrared Temperature (

instruments that have a minimum of 1 MΩ input impedance and accept safety
shrouded, standard diameter 0.16 in. (4 mm) banana plugs
Field of View
The meter’s field of view is 8:1, meaning that if the meter is 8 inches from the
target, the diameter of the object under test must be at least 1 inch. Other
distances are shown below in the field of view diagram. Refer to the chart
printed on the meter for more information.
Field of View
Make sure that the target is larger than the unit’s spot size. The smaller the
target, the closer you should be to it. When accuracy is critical, make sure the
target is at least twice as large as the spot size
