Time Function Processing
The LMG MkII contains a number of ‘ Time Function algorithms which help
deliver a more consistent temperature reading from a sometimes noisy,
changeable reading from the infrared thermometer.
The following sections help you choose and configure the time function most
appropriate for your application.
The Time functions available are shown in Fig. 4-1.

4.1 None
The LMG MkII will display the raw output from the Thermometer.
4.2 Averager
Refer to Fig. 4-2. The Averager time function can be used to ‘smooth’ the
temperature output signal in relation to the temperature input. The Averager
response can be adjusted to suit your application. With a fast response
speed, the temperature output signal tracks the input signal closely, any
rapid fluctuations in the input are reflected in the output. With a slow
response speed, the temperature output signal is much smoother, displaying
more the ‘trend’ of the input signal rather than rapid changes.
