2.3.3 Calculating Temperature Values
The thermometer calculates the MAX, MIN, dIF, and AVG
temperatures based on the current temperature.
To clear the “AVG ---” display, turn off the thermometer.
Every time the thermometer goes from the sleep mode to the
Real Time mode (by pulling the trigger) the MAX, MIN, dIF,
AVG and TC temperatures are updated.
2.3.4 Changing the Temperature from °F to °C (or vice versa)
During the time that the thermometer displays either MAX, MIN,
dIF, AVG or thermocouple temperatures, press the key to
change all the temperatures from °F to °C or vice versa.
2.3.5 Turning on the Display Backlighting
During the time that the thermometer displays either MAX, MIN,
dIF, AVG or thermocouple temperatures, press the key to
turn the display backlighting ON/OFF while the
unit is in LOCK mode and trigger is released. In addition, the
display backlight turns on automatically when the trigger is pulled.

“AVG ---” is displayed when either of the following conditions
occur:
1. When the average temperature measurement reaches its
time period as stated in the specifications.
2. When the thermometer is trying to measure a target
temperature which is outside of its measuring temperature
range.
is the maximum temperature
since the temperature
measurement session starts
(pulling the trigger).
is the minimum
temperature since the
temperature measurement
session starts.
is the difference between
the MAX and MIN
temperatures.
is the true average temperature since the temperature
measurement session starts. The average temperature under
continuous operation is accurate for a limited period of time
(refer to the specifications). However, the AVG temperature
function can be used indefinitely when the thermometer is
operating intermittently.
