5.1 Emissivity (ratio) Setting
If the emissivity (ration) of the object to be measured is low, displayed temperature indicates lower than the
actual measured temperature, so it is necessary for the emissivity (ratio) to be compensated.
Following procedure shows how to set emissivity (ratio) compensation according to the measuring object for
accurate measurement of the thermometer.
1) Turn ON the power by holding down
MEASURE
key.
Release
MEASURE
key to display status marker "HOLD".
2) Push
SEL
key several times while in the "HOLD" status and
display
"ε"
on the sub marker (
"εr"
for 2-color type).
3) Push
key or
key to change numeric value on the sub
display.
4) Blinking stops by pushing
ENT
key and the blinking digit moves
its position from lower place to the higher place and the
registration is completed.

・
Setting range single-color: 1.900 to 0.100
2-color: 1.200 to 0.800 (0.001 step)
・
Setting of factory default is 1.000.
Emissivity (ratio) setting can not be done while in memory input mode.
For canceling memory input mode, push
MEMORY
key to turn off "
" under main marker
・
If the emissivity of the object measured is known, set its value.
・
If the emissivity is unknown, measure the temperature of the object by thermocouple then
compare them and change emissivity to display the same value. For emissivity of typical
substance, refer to "13. Emissivity Table".
If no key operation has done for 30sec. while in "HOLD" state, power supply is turned OFF
automatically.
