This display shows the wireless transmission interval.
It can be set to 2, 10, 30, 60, 120 seconds using the Up and
Down arrow keys.
20
This display shows the unit ID address. It can set from

Enable Data Logging
You initiate logging data (Relative Humidity, Ambient
temperature, Infrared temperature, Thermocouple 1,
Thermocouple 2) by pressing the SET/REC key from the
following display menus: RH/Temp/IR (Main Menu)
RH/TC1/IR
RH/TC1/TC2
RH/TC1-TC2/IR
RH/Temp/TC2
The LOG display icon will turn on. The unit will log the
five sets of data until the internal memory gets full. It will
then stop logging data. The LOG display icon will blink
accompanied by a one-time 3 beep warning. You can also
stop logging data at any time by pressing the SET/REC
key again.
Infrared Function
You can set the target emissivity from screen
6
(from
Display Screens Explained Section). Simply aim the
infrared lens to the target object, press and hold the laser
button to turn on the laser beam. The laser beam indicates
either the center of the target object (Laser Dot) or the area
of the target being measured (Laser Circle). There is a 5/8
inch offset between the center of the optical field of view
and the laser beam. It may take a few moments for the IR
reading to stabilize.
