Operation Remarks
Thermocouple: Activate the functions just by
connecting to the connector
and switch to TC function.
E-smart: 1. In Emissivity mode, push the button
to enter the E-smart function.
2. Contact the target surface with
thermocouple.
3. Point the target with infrared
thermometer and push the measure
trigger till the buzzer beep.
The cross-reference Emissivity
value will be memorized in the unit.
4. Press the “Ｆ” button to leave
the E-smart function.
CIS: The color of backlight will change when the
target temperature exceeds the setting point
of alarm temperature.
Memory: Activate the record function by push
the “M” button. To delete all the
records, press up or down button to
DATA 0 and press “M” button.
Lock: Push the button to continuously measure
and display the temperature without pull the
measuring trigger.
Function: The above functions can be activated
always in any step of operations
mode in flow-chart.
Scan/Hold: In SCAN mode, the LCD displays both
the current temperature in Celsius
or Fahrenheit. The unit will HOLD the
last reading for 6 seconds after the
trigger is released.
When the battery is low, the battery
icon shows and the unit will
continue to function.
Data: While DATA# flashes on the left button ,
Dis
the value on the Main Temperature play
can be recorded in “#” log. Simply press
“M” button. 9

Field of View (FOV) ratio
=Distance to Spot Ratio
The field of view is the angle of vision at which
the instrument operates, and is determined by
the optics of the unit.The FOV is the ratio of the
distance from the target to the target diameter.
The smaller the target,the closer you should be
to it. When the target diameter is small, it is
important to bring the thermometer closer to the
target to insure that only the target is measured,
excluding the surroundings.

Emissivity
Emissivity is the ability of an object to emit or
absorb energy. Perfect emitters have an emissivity
of 1, emitting 100% of incident energy. An object
with an emissivity of 0.8 will absorb 80% and
reflect 20% of the incident energy. Emissivity is
defined as the ratio of the energy radiated by an
object at a given temperature to the energy emitted
by a perfect radiator at the same temperature. All
values of emissivity fall between 0.0 and 1.0.
6. Maintenance
Cleaning the lens: Blow off loose particles using
clean compressed air. Gently brush remaining
debris way with a camel's hair brush. Carefully
wipe the surface with a moist cotton swab. The
wab may be moistened with water.
NOTE:
DO NOT use solvents to clean the lens.
Cleaning the housing:
Use soap and water on a damp sponge or soft
cloth.
