7.6Setting for Moving Average Calculations (Dot-printing model)

Noise in the measured signal can be suppressed in the final measurement by computing a moving average. It is possible to record a moving average calculated over the previous X samples, selectable from the previous 2 samples up to the previous 16 samples. The purpose of the following setting is to select for each channel whether or not to compute a moving average, and if so, over how many samples.

(One sampling period is five seconds.)

The initial value is ‘OFF’.

Example: (let us assume a moving average over five samples is selected)

Select the channel No. using the [] key for which you want to compute a moving average. Then press the [ENT] key.

Use the [] key to select the number of samples. You can choose from ‘OFF’, ‘2’, ‘3’,

... up to ‘16’. Press the [ENT] key. The display [

] will appear.

Press the [ENT] key to continue the setting for other channels. The moving average setting has been completed, but has not been stored yet.
