Omega Engineering OS531 manual Calculating Temperature Values, Turning on the Display Backlighting

Using the Handheld Infrared Thermometer 2

2.3.3 Calculating Temperature Values

The thermometer calculates the MAX, MIN, dIF, and AVG temperatures based on the current temperature.

°F

is the maximum temperature since the temperature measurement session starts (pulling the trigger).

°F

is the minimum temperature since the temperature measurement session starts.

°F

is the difference between the MAX and MIN temperatures.

°F

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.

°F

“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.

To clear the “AVG ---” display, turn off the thermometer.

NOTE

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.
