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-keys to select the display ‘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
‘*M_AVE SET*’ will appear.
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.
Before leaving the SET UP Mode, you have to store your new settings. Press the ESC-
key to return to the ‘SETUP=M_AVE’ display and then select the ‘SETUP=END’
display.
Press the ENT-key. Select ‘END=STORE’ to keep your new settings or
‘END=ABORT’ and press the ENT-key. After a few seconds, the Operation Mode will
appear.
