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,  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. See Figure 3.
