KPS-TM15 • Non-contact infrared thermometer
ENG
Make sure that the target is larger than the units’s visual spot size; the smaller
the target, the closer the thermometer should be to it. The ratio between dis-
tance and spot size is
12: 1; the following drawing illustrates this:
To prevent the sensor from picking up IR radiation from additional sources,
make sure the thermometer is closer to the target object than the D:S ratio.
9. EMISSIVITY
Emissivity is a term used to describe the energy emitting characteristics of a
material. The greater the emissivity, the more energy the object is capable of
emitting. Most organic materials and oxidized metal surfaces have a emissivity
between 0.85 to 0.98. The thermometer’s sensor has the ability to be adjusted
to 3 different emissivity settings: high (0.95), medium (0.85) and low (0.75).
10. THERMAL BRIDGE
A thermal bridge is any object that allows the transfer of heat or energy from
one side to another. Because the surface temperature of an object at a thermal
bridge is lower than the rest of the room, the risk of mold increases significantly
at these locations.
11. CHANGING THE BATTERY
When the battery symbol appears on the display, it indicates that the battery
needs to be changed. Press the casing at the OPEN symbols on both sides
of the battery cover and pull it away from the meter to open the cover. See the
following drawing
