1. Quick Instructions
Press and hold the operating button for more than 1.5 seconds. The
temperature of the surface the lens is aimed at will read on the top of the
display. The minimum and maximum temperatures of the current
measurement are shown on the bottom of the display. When the operating
button is released "Hold" will be displayed between "min" and "max"
indicating the measurement is completed. After 4 seconds the backlight
will turn off. The unit will switch off after 8 seconds. Press and hold the
operating button again to begin a new measurement. To switch between °F
and °C simply "double click" the operating button.
2. Equipment Supplied
a.
Infrared Thermometer base unit
b. 4 button cell batteries (already in unit)
c.
Neck strap
d. Soft sided case
3. Description of measuring principle
When making a temperature measurement, the surface radiation of the
object to be measured is evaluated using the principle of radiation
thermometry. This is a purely passive process, i.e. no radiation is
transmitted, but instead, use is only made of the natural electromagnetic
radiation energy (heat radiation) that every body above a temperature of
absolute zero (-273 °C) has. The temperature can be determined very
accurately from this radiation energy if the emission factor of the object
being measured is known.
