Measurement Operation
Hold the meter by its
Handle Grip
and point it toward the surface to be
measured.
Pull and hold the
Trigger
to turn the meter on and begin testing. The
display will light if the battery is good. Replace the battery if the display
does not light.
While measuring, the SCAN display icon will appear in the upper left
corner of the LCD.
Release the Trigger and the HOLD icon will appear on the LCD
indicating that the reading is being held.
The meter will automatically power off after approximately 7 seconds
after the trigger is released. (Unless the unit is locked on)
How To Obtain Emissivity?
In the EMS mode, press and hold the Laser/Backlight button until the
“EMS”
icon on the left side of LCD blinking. At this time, “ɛ=--“ will
appear at the upper side of the LCD; IR temperature value will be in the
middle of LCD; and Type K temperature value is at the lower side of
the LCD.
Contact the Type K probe to the object surface and test the temperature
of same point with IR measurement. After both values are stable, press
“UP” or “DOWN” button for confirmation. Then emissivity of the
object will be shown at the upper side of the LCD.
Press
“MODE”
button or trigger to enter normal measurement.
Note:
When the IR value is not corresponding to the TK value, or IR and TK
tested the different points, no emissivity will be obtainable or a wrong
emissivity will be obtained.
The temperature of the target should be higher than the environment
temperature. Normally, 100˚C is suitable for obtaining a higher
accuracy emissivity.
After obtaining the emissivity, if the difference between IR value (in the
middle of LCD) and TK value ( at the lower side of LCD) is too big,
they obtained emissivity will be incorrect. It’s necessary to obtain a new
emissivity.
