, then press
Mode key () to confirm it. The emissivity can be changed from 0.10 (10E) to 1 (100E).
Press Mode key () for scrolling more display function as follows.
Here will show the emissivity data. (The default emissivity is 0.95.)
Press Mode key () for the

o
C, the Low
icon will flash and you will hear a beep sound.
Connect the thermocouple with TN4’s Thermocouple socket () and put the probe in the target,
press Meas. key () display t
he temperature in PRB mode.

DIF, AVG, PRG
mode:
Press Up key () for
LOCK mode
ON/OFF.
The lock mode is particularly useful for
