5.2 Auto Emmisivity Setting by Thermocouple
The thermometer has a function of contact type thermometer using K thermocouple.
Furthermore, the emissivity of the thermometer can be automatically set by assuming the contact
temperature measured by the thermocouple as a true temperature.
For turning "on" thermocouple measurement (thermocouple measurement enable), execute the setting
according to the section "6.6 Thermocouple Measurement Selection".
1) Turn ON the power by holding down
MEASURE
key.
Release
MEASURE
key to display status marker "HOLD".
2) Peel the connector cover and connect the thermocouple.
3) Push
SEL
key several times while in "HOLD" status and display
sub marker "TC".
4) Attach the tip of thermocouple to the object to be measured then
push
MEASURE
key to take measurements by the thermometer
and by the thermocouple simultaneously. Temperature
measured by the thermocouple is indicated on the sub display.
*There are two types of measuring mode. Refer to "7.1 Standard
Measuring Mode" and "7.2 Continuous Measuring Mode".
5) Emissivity is set automatically, after the measurement, by
pushing
ENT
key while in the "HOLD" status,
6) By pushing
SEL
key several times to display sub marker "ε" ,
you can check the set emissivity.
Caution
Reference
Remark
Caution
If "on" (thermocouple measurement enable) is set, but the thermocouple is not connected, "oFL" is
displayed on the sub display.
Thermocouple input setting of factory default is "oFF"
(thermocouple measurement disable).
Pay attention to the thermocouple position and
connect it properly.
Measuring range of the thermocouple is
300 to 800°C (IR-HAI)
600 to 800°C (IR-HAS)
Single-color: 400 to 800°C, 2-color: 600 to 800°C (IR-HAQ)
