Pushbuttons
Pushbutton Description
G
Press and hold G to display the object’s surface
temperature. The thermometer clears any stored
maximum and minimum temperatures. The laser
pointer only activates if the laser switch is in the on
position.
While
G is pressed, the display shows HHHHH.
Release
G to stop measuring temperatures and
deactivate the laser. The display continues to show
the most recent temperature and
Cfor 20
seconds. Then the display turns off.
F
Press F to display the maximum measured
temperature. The display shows MAX.
Press
F a second time to display the minimum
measured temperature. The display shows MIN.
Press
F a third time to turn off this function.
E Press E and hold for 1 second to save the
displayed temperature. The display flashes TEMP
MEM 5 times to indicate that the operation is
successful.
Press
E to display a stored temperature. The
display shows TEMP MEM. Press
E again to
turn off this function.
D
Press D to switch between
o
C and
o
F.
Pressing any of the three top pushbuttons wakes up
the thermometer.

- Emissivity 5
- Emissivity is a value between 0 and 1 that indicates an object s ability to emit infrared energy emissivity is determined primarily by the object s composition and surface finish a polished non oxidized metallic surface has an emissivity value near 0 and a dull black surface has an emissivity value near 1 see emissivity of common materials 5
- Ensuring accuracy 5
- Model 65 english instruction sheet page 5 5
- The thermometer s sensitivity to emissivity is set at the factory to 0 5 if the emissivity of the object is not 0 5 the displayed temperature could differ from the actual surface temperature to reduce this difference apply black tape black matte paint or black magic marker to the object if it is safe to do so and measure the darkened surface 5
- Laser offset 6
- Model 65 english instruction sheet page 6 6
- Optical resolution 6
- Optical resolution also called field of view or distance to spot size ratio is the ratio of the thermometer s distance from the object s surface to the size of the area measured spot size the closer the thermometer is to the object the smaller the spot size the laser spot size does not indicate the measured spot size see laser offset 6
- Surface temperatures 6
- The laser beam is offset 18 mm 0 5 in from the focal lens choose a sampling spot large enough to include the laser offset 6
- The minimum spot size is 25 mm 1 in which occurs at a distance of 200 mm 8 in from the object you cannot measure a smaller spot size by getting closer 6
- The temperature displayed is an average temperature within the spot size hot spots can be missed if the spot size is too large get as close as possible but no closer than 200 mm 8 in 6
- The thermometer has an 8 1 optical resolution 6
- The thermometer measures the first surface it detects even a glass cover dust or fog make sure the object is not obstructed 6
- And aim the laser beam in the center of the area to be measured the display shows the measured temperature 7
- If the emissivity of the object is different from 0 5 apply black tape black matte paint or black magic marker to the object if it is safe to do so see the section emissivity of common materials 7
- Measuring temperatures 7

- Out of range hi flashes 7
- Out of range lo flashes 7
- Out of range temperatures 7
- Point the thermometer at the object 7
- Read the section ensuring accuracy before measuring temperatures check that the batteries are installed and the laser switch is in the on position see the sections installing the batteries and setting the switches 7
- Temperature display 7
- Temperature does not flash 7
- Temperature flashes 7
- The display indicates when a measured temperature reaches the detection limits of the thermometer when you recall an out of range temperature the display shows lo and hi as 7
