General 
 
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. 
 
Operation
