Figure 2. Infrared Thermometer
Display
The primary temperature display reports the current or last IR temperature read until the 7-
second hold time elapses.
The secondary temperature display reports current thermocouple temperature when a type-K
thermocouple is attached. When a thermocouple is not connected, the small temperature
display reports a choice of maximum, minimum, or difference between maximum and minimum
temperature.
You can toggle through the minimum, maximum, and difference IR temperatures anytime the
display is on. The MIN, MAX, and DIF temperatures are constantly calculated and updated
when the trigger is pressed. After the trigger is released, the MIN, MAX, DIF temperatures are
held for 7 seconds.
Note
When the battery is low, B appears on the display.
The last selection (MIN/MAX/DIF) is maintained on the secondary display even after the
Thermometer has been turned off, providing the batteries have not failed.
