Programming WM5 96
T
his function allows the user to select the calculation method of the
DMD/AVG value of the selected variable. To access these functions
select DMD/AVG CALCUL. from the main menu by means of the “
” keys and confirm the selection with “S” (1).
TYPE (2): select the type of calculation mode to be used for the
D
MD/AVG calculation: FIXED or SLIDE (3). Select the desired type (3)
by means of the “ ” keys and confirm with “S”.
T
IME
(
4): select the time interval for the DMD/AVG calculation (5, 10,
15, 20, 30, 60 minutes). Select the desired time (5) by means of the
” keys and confirm with “S”.
FIXED SELECTION: if, for example, a time interval of 15 minutes has
been selected, the instrument will calculate the AVD/DMD value of the
measured variable and updates its value every 15 minutes.
SLIDING SELECTION: if for example a time interval of 15 minutes has
been selected, the instrument calculates the AVG/DMD value and
updates its value at the beginning after the first 15 values and then
after every minute, thus generating a window whose width is of 15
minutes and that moves forward every minute.
SYNCHRONISM (6): select the synchronization mode, that is the
method that controls the calculation method of the average/demand
according to the selected time. Select the type of desired synchronism
(7) by means of the “ ” keys and confirm with “S”.
OFF (7)
: the synchronization calculation starts when you switch the
instrument on.
CLOCK (7): the synchronization starts as soon as the first selected
integration time multiple expir
es. Example: by setting the integration
time at 10 minutes and the current time at 10:25, the synchronization
will start at 10:30.
CONTACT (7): the synchronization starts at the status modification
(from ON to OFF or from OFF to ON) of one of the digital inputs pro-
grammed such as SYNCHRONIZATION or TARIFF (see “DIGITAL
INPUTS”). A consequent status change produces the reset and then
again the starting up of the synchr
onization.
