10 CHANGE PAS: this function allows the user to modify the PASS value
with a new value (from 0 to 9999).
20 BACKLIGHT: backlight time from 0 (always on) to 255 minutes.
30 MODULES: the WM30 96 supports either automatic (A) or manual (M)
acknowledgment of the installed modules depending on the kind of
module.
40 APPLICAT.: this function which enables a simple, quick, clear and
immediate visualization of the instrument measur
ements, making available
only specific variables (page 4/5) depending on the application of the
instrument.
50 SYSTEM: this function allows the user to select the type of
electrical system.
60 CT RATIO: this function allows the user to select the
value of the CT ratio (primary/secondary ratio of the curr
ent transformer
being used). Example: if the CT primary (current transformer) has a current
of 300A and the secondary a current of 5A, the CT ratio corresponds to 60
(obtained using the following calculation: 300/5.
70 PT RATIO: this function allows you to select the value of the VT
-PT ratio
(primary/secondary ratio of the voltage transformer being used). Example:
if the primary of the connected VT (voltage transformer/potential trans-
former) is 20kV and the secondary is 100V, then the VT-PT ratio corre-
sponds to 200 (obtained carrying out the following calculation:
20000/100).
80 DMD: This function allows the user to select the calculation method of
the DMD/AVG value of the selected variable. 81 TYPE: select the type of
calculation mode to be used for the DMD/AVG calculation FIXED: if, for
example, a time interval of 15 minutes has been selected, the instrument
will calculate the AVG/DMD value of the measured variable and updates
its value every 15 minutes, after that resets and starts a new calculation.
SLIDE: 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 gener-
ating a window whose width is of 15 minutes and that moves forwar
d
every minute. 82 TIME: select the time interval for the DMD/AVG calcula-
tion 83 SYNC: select the synchronization mode, that is the method that
controls the calculation method of the average/demand according to the
selected time.
90 SET POWER: This menu allows you to set a power value (installed power)
that, in the measuring phase, will represent 100% of the graph indicator.
100 HOME PAGE: This function allows the user to select the variables to
be displayed on first page (home page). 101 TYPE: A, you can select the
variable for each row. B, you can select a preset combination of variables
(see relevant chapter to next page). 106 PAGE: select a preset series of
variables (see r
elevant chapter to next page).
110 FILTER: with the digital filter it’s possible to stabilize the measure-
ments which are too instable when displaying the relevant values. 111 FIL-
TER S: set the operating range (span) of the digital filter
. The value is
expressed as a % (filter to 0.0 means filter excluded). 112 FILTER CO: set
the filtering coefficient of the instantaneous measures. By increasing the
value, also the stability and the settling time of the measur
es ar
e
increased.
Some specific menus display only if the r
elevant modules are installed
