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.
