10.2 Moving Average
10.2.1
Function of moving average
Assuming that the moving average times is "n", this function is to calculate and output the mean
value of n preceding measured values each time. The function is used when an averaged output is
required such as for density control. This function is also useful for suppressing the deflection width
of output.
The value that can be set as the moving average times "n" is 1 to 99. Setting 1 for "n" means that no
moving average takes place.
10.2.2
Setting of the moving average times
(1) Switching to the setting mode (see Subsection 5.2.5)
First of all, press the [ESC] key of the converter several times (normally once although this
varies with the operation status) to return to the initial menu display. Next, use the [→] key to
move the LCD indicator cursor to the menu number "2" of "2 SETTING MENU" and then
press the [SET] key to display the warning message saying "Test output will be valid." Make
sure that there is no problem and then press [→] to get into the setting mode. And return to [2:
SETTING MENU]. Then, the output will be switched to the simulated output that is set
beforehand.
(2) Selecting the parameter setting menu (see Subsection 5.2.10)
In the state that the menu list of menu numbers 5 to 8 is displayed, use the [→] key to move the
LCD indicator cursor to the menu number "5" of "5: SET PARAMETERS" and then press the
[SET] key to select the menu of "5: SET PARAMETERS."
(3) Verifying or setting the moving average times (see Subsection 5.2.10)
Press the [DN] key three times (or the [UP] key eleven times) to display "ma: AVERAGING
TIMES". On this screen, it is possible to verify the set value of the moving average times. If it
is necessary to change the setting, press the [SET] key here to switch to the setup display of
the moving average times and enter an appropriate value. Use the [→] key to move to the digit,
and use the [UP] or [DN] key to alter the numeric value of the relevant digit. When entering
input is completed, press the [SET] key to confirm it. The screen will be returned to the
immediately preceding one; make sure that the value is correctly reset.
(4) Returning to the measuring mode
Press the [ESC] key twice to return to the initial menu screen and return to the measuring
mode from the setting mode to resume the normal measurement.
10.2.3
Cautions in using the moving average function
Setting an excessively large value for the moving average times will result in deteriorated
responsiveness. Therefore, make sure to set a value appropriate to the process situation and the
required responsiveness.
function can be used to facilitate the density measurement of up
to four different types of matters (brand) which differ in
measurement sensitivity.
