Measurement operation
1. Hold the meter by its Handle Grip and point it toward the surface to be measured.
2. Pull and hold the Trigger to turn the meter on and begin testing. The display will light if
the battery is good. Replace the battery if the display does not light.
3. Release the Trigger and the HOLD display icon will appear on the LCD indicating that
the reading is being held. In HOLD status, press the UP button to turn on or off the laser.
And press the DOWN button to turn on or off the backlight.
4. The meter will automatically power down after approximately 7 seconds after the trigger
is released.(Unless the unit is locked on)
Measurement considerations
Holding the meter by its handle, point the IR Sensor toward the object whose temperature
is to be measured. The meter automatically compensates for temperature deviations from
ambient temperature. Keep in mind that it will take up to 30 minutes to adjust to wide
ambient temperatures are to be measured followed by high temperature measurements,
some time (several minutes) is required after the low (and before the high) temperature
measurements are made.
This is a result of the cooling process, which must take place for the IR sensor
Battery replacement
1. As battery power is not sufficient, LCD will display “ ” replacement
with one new battery type 9V is required.
2. Open battery cover, then take out the battery from instrument and
replace with a new 9-Volt battery and place the battery cover back.
Notes:
How it Works
Infrared thermometers measure the surface temperature of an object. The unit’s optics
sense emitted, reflected, and transmitted energy, which is collected and focused onto a
detector. The unit’s electronics translate the information into a temperature reading, which
is display on the unit. In units with a laser, the laser is used for aiming purposes only.
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.
