EMISSIVITY 
Emissivity adjustment is optional. Emissivity adjustments are used to provide a 
truer temperature reading. Different materials radiate infrared energy at slightly 
different temperatures. The emissivity adjustment is used to compensate for 
different types of materials. The default emissivity of 0.95 will cover 90% of 
typical applications. 
The emissivity table provides a guide of different emissivity values for different 
materials. 
When the emissivity of an object is unknown use a non-infrared thermometer, 
such as a thermometer with a surface probe to measure the object’s surface 
temperature. Adjust the emissivity until the temperature of the infrared 
thermometer matches the temperature of the surface probe. The emissivity 
value arrived at by this method may be used to measure similar materials. 
 
To adjust the emissivity (optional): 
1. Press and release the trigger to turn on the display. 
2. With a pointed object, press the EMIS. button, until ▲E▼ appears on the 
display.
3. To adjust the emissivity value, press the ↑ and ↓ buttons. (Do not press the
trigger while adjusting the emissivity value). Press and hold to advance the 
display rapidly. The emissivity can be set from 0.10 to 1.00. 
4. Once the desired emissivity value appears on the display, press MODE
button to confirm the value. (▲E▼ will no longer appear on the display.)
This emissivity value will be used for all temperature measurements until the 
value is reset. 
 
DISPLAY MESSAGES 
“Er2” will appear on the display when the unit is exposed to rapid changes in 
ambient temperature. 
“Er3” will appear on the display when the ambient temperature is below 32° 
F (0° C) or above 122° F (50° C). 
“Er” will appear on the display when the unit needs to be reset. To reset the 
unit, remove the batteries, wait 2 minutes and then reinstall the batteries. 
 
ALL OPERATIONAL DIFFICULTIES 
If this thermometer does not function properly for any reason, replace the 
batteries with new high-quality batteries (see Battery Replacement section). Low 
battery power can occasionally cause any number of “apparent” operational 
difficulties. Replacing the batteries with new fresh batteries will solve most 
difficulties. 
 
BATTERY REPLACEMENT 
Erratic readings, faint readings, no display, or 
appearing on the display
are all indications that the batteries must be replaced. Open the battery 
compartment by sliding the battery cover in the direction indicated by the arrow 
and then lift the battery cover. Remove the exhausted batteries and replace 
them with two (2) new AAA alkaline batteries. Make certain to install the new 
batteries in the directions indicated in the battery compartment. Close the 
battery cover.
