2.3 TURNING THE INSTRUMENT ON
Simply move the toggle switch on the Rear Panel entitled “PWR” to On. The “PWR” switch is located on the left side of the Rear Panel.
2.4EMISSIVITY SETTINGS
(Target Emission Efficiency in %)
Emissivity Compensation is done by pushing the “plus” (+) or “minus”
2.5 SURFACE TEMPERATURE MEASUREMENT
The infrared surface temperature measurement can be made by selecting “IR” by pushing the “SEL” button the number of times necessary until the light comes on above “IR.” Then, when the instrument is on, the numbers on the display indicate
the Infrared Surface Temperature.
2.6 TEMPERATURE DIFFERENTIAL
To take the Temperature Differential (Patent No. 4,301,682) between the target temperature and the dry bulb ambient air temperature, first press the “SEL” button the number of times necessary until the light is shown above “DIFF.” Then, pull
the antenna out of the front of the instrument. This removes the sensor on the end of the antenna from the heating and cooling effects of the instrument and the operator’s hand. Now, when the instrument is on, the Temperature Differential will be read out on the Liquid Crystal Display. Let the instrument equilibrate for at least ten (10) minutes before making Differential readings for better accuracy.
2.7AMBIENT TEMPERATURE MEASUREMENT
The Dry Bulb Ambient Air Temperature can be measured by pushing the “SEL” button the number of times necessary until the light is on above the “AMB” notation. Now, when the infrared thermometer is on, the display is indicating the
Dry Bulb Ambient Air Temperature.
