MEASURMENT 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 While measuring, the SCAN display icon will appear in the upper left hand corner of the LCD.
④ Release the Trigger and the HOLD display icon will appear on the LCD indicating that the reading is being held.
⑤The meter will automatically power down after approximately 7 seconds after the trigger is released.
Note: 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.
7. BATTERY REPLACEMENT
① As battery power is not sufficient, LCD will display "
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.
8. 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.
Distance & Spot Size
As the distance (D) from the object increases, the spot size (S) of the area measured by the unit becomes larger.
See: Fig: 1.
Locating a hot Spot
To find a hot spot aim the thermometer outside the area of interest, then scan across with an up and down motion
until you locate hot spot.
Reminders
① Not recommended for use in measuring shiny or polished metal surfaces (stainless steel, aluminum, etc.).See
Emissivity
② The unit cannot measure through transparent surfaces such as glass. It will measure the surface temperature of
the glass instead.
" replacement with one new battery type 9V is required.
