9.2.5 How to Select a Moving Average (Dot 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.
The initial value is ‘
OFF
’.
Example: (let us assume a moving average over 5 samples is selected)
SETTING PROCEDURE:
Enter the SET UP Mode by turning ‘
ON
’ the power while pressing and holding the
ENT
-key until the SET UP display appears.
Use the
UP/DOWN

SETUP=M_AVE
’. Press the
ENT
-key.
Select the channel No. for which you want to compute a moving average. Then press
the
ENT
-key.
Select the number of samples. You can choose from 2 samples, 3 samples, ... up to 16
samples. Of course you can also select OFF. Press the
ENT
-key. The display

The moving average setting has been completed, but has not been stored yet. Press the
ENT
-key to continue the setting for other channels or the
ESC
-key to adjust other
settings in the SET UP Mode.
