DESCRIPTION OF THE INSTRUMENT
Reading and programming optical port. The optical port is equipped with a detachable device for the
integration of the magnetic fixing reading head.
Colour Bar-graf to show at a glance the status of the single phases L1-L2-L3.
Active virtual alarms warners.
Current energy drain indicator (kWh) by means of flashing, proportional to the measured energy (the
higher the flashing frequency, the higher the energy drained. Max. frequency 16Hz pursuant to stan-
dard EN5047-1).
The keyboard is divided into two areas, the top area is dedicated to the measurements with direct access
to specific visualization screens.
Visualization of the counters screens: each pressure of the button corresponds to the visualization of
a screen with counters related to different energies (see the table with the measurement screens
below).
Visualization of the current voltage and frequency (see the table with the measurement screens below).
Visualization of the instant cosϕand powers (see the table with the measurement screens below).
Visualization of the harmonics (see the table with the measurement screens below).
The keyboard in the bottom area is especially dedicated to instrument programming.
Exits the submenus, exits programming.
“Up” button, enables to browse the menus and to increase the values to be set.
“Down” button, enables to browse the menus and to decrease the values to be set.
Access to the programming menu: hold pressed for at least 2 seconds to access the program-
ming menu.
In measurement mode, buttons 8 and 9 enable to display the MAX and dmd values of the displayed
variables.
The buttons are enhanced touch buttons. To check their actual engagement, a specific icon on the
display turns on each time a button is pressed.

ADDITIONAL FUNCTIONS OF THE BUTTONS
The buttons featuring a double icon have two functions, to access the secondary function,
hold pressed for a long time the button corresponding to the desired secondary function.
Access to the instrument information screens: reference standards, firmware ver-
sion, year of manufacturing.
“Home” button: from any measurement screen, from any menu, returns to the
main measurement screen (customizable by the user). If you are in the program-
ming menu, any data entered is lost.
Holding pressed the button 10, you access the reset of the MAX of the displayed
variables.
Holding pressed button 11, you access the reset of the dmd's of the displayed
variables.
The reset must be confirmed by button 12.

HOW TO SET THE VALUES
With WM40 the values setting is even more simple, it is possible to increase or decrease every single digit,
it is possible to easily obtain the wished value or change directly from one multiplier to another one.
Example: use of the menu relevant to the current ratio.
During the programming phase the instrument provides useful information:
recognition of the programming mode;
identifier number of the menu (see also the programming flow chart);
edit, identification of the line subject to set;
cursor that identifies the digit subject to set;
maximum and minimum limit of selectable variable.
Use the keys 6to increase and decrease the digit detected by the cursor (d).To set another digit move
the cursor to match the wished digit using the key 4,every key press corresponds to a left shifting of the
cursor (d).
When the last digit on the left is matched by the cursor (d), a further press of the key 4allows to
change the decimal point and the multiplier (f) (k o M), the blinking “dP” (decimal point) text (g) identifies
that the instrument is able to do this function.
To modify the decimal point position and the multiplier use the keys 6to have the wished value.
To confirm the set value press the key 7.
To cancel the operation in progress and come back to the starting condition press the key 5.
To cancel the operation in progress and come back to the measuring “Home” page, press and keep press-
ing the key 5at least 2 seconds.

Where:
Pmax is the maximum power,
Pc is the contractual power,
t1 is the selected time period for the calculation of the AVG/DMD value.
FIXED SELECTION:if, for example, a time interval of 15 minutes has been selected, the instrument will cal-
culate the AVG/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 calcu-
lates 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 forwardevery minute.
SELECTION OF DMD CALCULATION: 111 TYPE: 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 instru-
ment 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 generating a window whose width is of 15 minutes and that moves forward every minute.

DIGITAL FILTER PROGRAMMING EXAMPLES
Example 1
How to stabilize the value of the VL-N variable displayed on the dis-
play, fluctuating from 222V and 228V.
The parameters of the digital filter have to be programmed as follows:
FILTER S: the variable has fluctuations within the mean value whose
amplitude is equal to ±0,75% of the full scale rated value of the variable
itself (obtained by the following calculation: (228-222)/ 2= ±3V, then
±3*100/400V= ±0,75% where 400V is the phase-neutral rated value of an
AV5 input). The “range” parameter,representing the action range of the
digital filter, is to be programmed to a value which must be slightly high-
er than the percentage amplitude of the fluctuation: ex. 1.0%.
FILTER CO: if the new value measured by the instrument is within the
action range of the filter, the new displayed value is obtained by adding
algebrically the previous value to the variation divided by the filtering
coefficient. As a consequence, a value higher than this coefficient implies
alonger settling time and therefore a better stability. You generally obtain
the best result by setting the filtering coefficient to a value equal to at
least 10 times the range parameter value.
In the following example: 1,0*10=10, the stability of the filtering coeffi-
cient can be improved by increasing the filtering coefficient, the allowed
values are included within 1 and 255.
Example 2
How to stabilize the value of the displayed System Active Power
(W∑), fluctuating between 300kW and 320kW (the load is connected
to the instrument by means of a 300/5A CT and a direct measure of
the voltage).
The parameters of the digital filter must be programmed as follows:
FILTER S: the variable has fluctuations within the mean value whose
amplitude is equal to ±2,78% of the full scale rated value of this variable.
This value is obtained by the following calculation: (320-300)/ 2= ±10kW,
then ±10*100/360kW= ±2,78%, where 360kW is the rated value of the
System Active Power of an AV5 input, at the above mentioned CT and VT
ratios and obtained by means of the following formula: “VLN * VT * IN *
CT * 3” where VLN = rated input voltage (400V for the AV5 input), VT= pri-
mary/secondary ratio of the voltage transformer being used, IN = rated
current (5A for the AV5 type input), CT = primary/secondary ratio of the
voltage transformer being used (in this example “400*1*5*60*3=360kW).
The RANGE parameter, representing the digital filtering coefficient action
range, is to be programmed to a value which must be slightly higher than
the percentage of the fluctuation: eg. 3.0%.
FILTER CO: if the new value acquired by the instrument is within the fil-
tering action range, the new displayed value is obtained by adding alge-
brically the previous value to the variation divided by the filtering coeffi-
cient. As a consequence, a value higher than this coefficient implies an
higher settling time and therefore a better stability. Generally speaking the
best result is obtained setting the filtering coefficient to a value equal to
at least 10 times the value of the range parameters. In the example:
3.0*10=30. In order to improve the stability you can increase the filtering
coefficient, the admitted values are included within 1 and 255.
Example 3.
It’s necessary to stabilize the value of the displayed variable AL 1
(phase current 1), fluctuating within 470V and 486V.
To be able to manage the alarm function and activation and deactivation
of the relay, this value is not to be subject to continuous fluctuations. In
this example we have considered using a 500/5A CT.The parameters of
the digital filter is to be programmed as follows:
FILTER S: the variable has fluctuations within the mean value whose
amplitude is equal to ±1,60% of the full scale rated value of this variable
(obtained by means of the calculation: (486-470)/ 2= ±8A, then
±8*100/500A= ±1,60% where 500A is the value referred to the primary of
the transformer being used). The “range” parameter,which represents the
action range of the digital filter, is to be programmed to a value slightly
higher than the pourcentage amplitude of the fluctuation: for example
2.0%.
FILTER CO: if the new value acquired by the instrument is within the fil-
tering action range, the new displayed value is calculated algebrically
adding to the previous value the variation divided by the filtering coeffi-
cient. As a consequence, a higher value of this coefficient implies a high-
er settling time and therefore a better stability. Generally speaking, the
best result is obtained setting the filtering coefficient at a value equal to
at least 10 times the value of the range parameter. In the example:
2.0*10=20. Toimprove the stability you can increase the filtering coeffi-
cient, the admitted values are within 1 and 255.

WHAT IS THE ACTION OF THE DIGITAL FILTER PARAMETERS ON THE MEASURE?
The first filter parameter is FILTER S and defines the operating range of the filter. This operating range is represented as a yellow band
in figure on left side (each small square is one digit). Until the measured value (red curve in figure) is within this band, the filter is active;
as soon as the value is external, the filter is deactivated and a new band will be active around the new value.
The range of the fluctuation (in digit) is a good starting value for such parameters.
The suggestion to set this parameter is to look at the size of the fluctuation (in digit) and use this value.
The second parameter is FILTER CO and represents the filtering coefficient. The higher is FILTER CO,the smoother is the curve of the
displayed values (black in figure). There is not a theoretical rule to define this parameter, it is to be set on the field: however a rough
suggestion is to start with the same value of the FILTER S coefficient and then increase it until the desired stability is reached.
The digital filter affects the values retransmitted both via serial communication and analogue output.

PROGRAMMING EXAMPLES OF THE ANALOGUE OUTPUTS
Power retransmission by means of a 0-20mA analogue output.
It’s necessary to measure a consumed power up to 100kW and retrans-
mit this value by means of a signal from 4 to 20 mA: the module to be
used is MOV2 (2x from 0 to 20mA), the instrument is to be programmed
as follows:
VARIABLE: W∑(system active power).
MIN OUT: 20.0% means 4 mA. The calculation to be carried out is the fol-
lowing: (100*minimum output) / fullscale output =100*4mA/ 20mA=20%.
MAX OUT: 100.0% means 20mA. The calculation to be carried out is:
(100*maximum output) / fullscale output = 100*20mA/20mA= 100.
MIN INPUT: 0,0k; the multiple k,M,G can be selected on the instrument
according to the chosen VT and CT values.
MAX INPUT: 100.0k; the k, M, G multiples can be selected on the instru-
ment according to the selected VT and CT values.
Retransmission of the POWER FACTOR (PF) by means of the
0-20mA analog output.
It’s necessary to retransmit the whole range of the allowed values for the
PF with a signal from 0 to 20mA. Particular attention must be paid to the
value of the PF variable which may vary from C0,001 and L0,000 (for each
phase): these values will be retransmitted and will then correspond to 0
and 20 mA. When the PF will have a value equal to 1, being in the mid-
dle between C0,001 and L0,000, the value of the output will correspond
to the middle of the scale, that is 10mA. As a consequence, the instru-
ment will have to be programmed as follows:
VARIABLE: PF L1 (or L2 or L3 or PF∑).
MIN OUT: 0,0%.
MAX OUT: 100,0%.
MIN INPUT:C0,001 (the C symbol shows a CAPACITIVE value).
MAX INPUT: L0,001 (the L symbol shows an INDUCTIVE value). L0,001
has been chosen as minimum value to be set in order to avoid any unde-
sirable swifting of the repeated outputs.
