SAFETY INFORMATION  
Read the following safety information carefully before  
attempting to operate or service the meter.  
Only qualified personnel should perform repairs or  
servicing not covered in this manual.  
Periodically wipe the case with a dry cloth. Do not use  
abrasives or solvents on this instrument.  
Safety symbols:  
Dangerous, refer to this manual before using the  
meter.  
Apply with European CE.  
This instrument conforms to the following standards:  
EN50081-1: 1992 Electromagnetic Emissions  
EN50082-1: 1997 Electromagnetic Susceptibility  
Test were conducted using a frequency range of 80-1000  
MHz with the instrument in three orientations. The average  
error for the three orientations is ± 2.0°C (±4.0°F) at 3V/m  
throughout the spectrum. However, between 300 MHz and  
500 MHz at 3V/m, the instrument may not meet its stated  
accuracy.  
Warning of laser!  
Do not point laser directly at human eye or  
indirectly from reflective surfaces.  
II. CAUTIONS  
Before using the infrared thermometer the operator must  
notice the following:

Keep away from electrical welders, induction heaters  
and EMF sources.  
When using this thermometer under large or abrupt  
ambient temperature change, allow 15 minutes for unit  
to stabilize before use.  
Do not keep this thermometer in the environment of  
high temperature for a long time.  
Keep away from dusty environment, and keep in carry  
case after operation to avoid contamination of optical  
lenses.

V. OPERATION INSTRUCTIONS  
Measuring Trigger  
To measure a temperature, point the unit at an object and  
pull the trigger. Be sure to consider distance-to-spot size  
ratio and field of view. The laser is used for aiming the  
target for reference. The temperature reading will be  
updated on the LCD. When the operator releases the  
trigger, the reading will automatically be held on the LCD  
for 10 more seconds. After 10 seconds this thermometer  
will power down itself to save battery.  
Distance to Spot Ratio (D/S)  
You have to make sure that the detection area you want  
to measure is larger than the required spot size to get a  
correct reading. The temperature you get is an average  
temperature of the detected region. The smaller the target,  
the shorter distance is required for the measuring.

Emissivity  
Emissivity is a term used to describe the energy-emitting  
characteristics of materials. The higher of this value  
means the more capability of radiation emittance the  
materials has. Most organic materials and painted or  
oxidized surfaces have an emissivity of 0.98. Metal  
surfaces or shiny materials has a lower emissivity and

give inaccurate readings. Please note this during  
applications.  
Maintenance  
Blow off loose particles using a lens blow. Gently brush  
remaining debris away with a lens brush. Carefully wipe  
the surface with a moist cotton swab. The swab may be  
moistened with water.  
NOTE: Don’t use solvents to clean the lens.  
Replace Battery
