The thermometer accepts thermocouple input. It displays thermocouple temperature and the target temperature (via infrared) simultaneously. This function provides an accurate method of determining an unknown emissivity.

•To Determine an unknown target emissivity

1.Connect a contact thermocouple probe (Type K) to the thermometer as shown in Figure 1-3.

2.Measure the object temperature using the thermocouple probe.

3.Aim at the object and measure the temperature via infrared.

4.Press and hold the key until the Emissivity Display mode (E) appears.

5.Set the emissivity by pressing the or keys until the temperature reading matches the thermocouple

temperature measurement.

6.The thermometer now displays the correct object emissivity.

"TC--- is” is displayed when the thermocouple input is open or out of range (0 to 1600°F).
