■PQTSoft Remote in brief
PQTSoft Remote has been conceived to program PQT-90
by means of a data transmission from the PC to the instru-
ment via RS232 or RS485 serial interface. The choice
between one interface or the other is therefore very impor-
tant for the correct operation of the instrument as shown
by the following figure:
Local single PQT connected to
the PC by RS232 serial port
Maximum 255 PQT’s in an RS485 local network connected
to the PC by RS232 thanks to the RS485-RS232 SIU-PC
converter.
Maximum 100 remote single PQT’s connected to the PC by
means of a telephone network thanks to an analogue/GSM
modem.
Maximum 25000 PQT’s in max 100 remote RS485 networks
connected to the PC by means of a telephone network and
RS485-RS232 SIU-PC.

PQTSoft Remote manages a configuration archive that may be
selected at any time. At first, when the software has just been
installed, this file is empty. [1] Click on new configuration to start
the programming procedure of PQT90. [2] It allows to load from
PQT-90 the pre-existing programming and to modify it, if
required. [3] Close the window without modifications.
❑Instrument composition...
[1] Enter the name required for the new configuration of PQT-90.
[2] Select the supplied modules installed in the instrument in
the various slots. For the module AR1041 only, if it is present,
also the operating mode is to be indicated as follows:
“AR1041 module (slave)”: PQT-90 is enabled to the data-
download only on request of the user;
“AR1041 module with analogue or GSM (Master+Slave)”
modem: PQT-90 is enabled to the data download on request
and to the independent transmission of SMS in case of
alarm activation;
“AR1041 module with GSM modem for SMS (Master)”:
PQT-90 is enabled to transmit SMS messages and to send

or without analogue measuring inputs (AQ1018, AQ10109)
[2] Enables the gas and water metering.
[3] Selects the ratio of the current transformer. Example: if
the CT (current transformer) primary has a current of 300A
and the secondary a current of 5A, the CT ratio corresponds
to 60 (that results from: 300/5).
[4] Selects the value of the VT (voltage transformer) ratio.
Example: if the VT primary connected to the instrument is
20kV and the secondary is 100V, the VT ratio corresponds
to 200 (resulting from 20000/100).
[5] Selects the serial address of the instrument when the lat-
ter is part of a network of instruments.
[6] Selects the type of electrical system. If no measuring
inputs (AQ1018, AQ1019) have been selected on the previ-
ous page, the box “Full scale power” will appear: select the
most appropriate full scale.
[7] Selects the options for the clock of PQT-90. If the option
“Not to be programmed” is selected, the clock will not be
programmed; to program the hour, select the option
“Synchronize with PC date and hour”, the clock will be pro-
grammed with the date and hour present in the system of
the PC. To make the instrument automatically switch to the
summer time and viceversa, select the option “Automatic
switching to summer time”.

and C2 are not available if PQT-90 is supplied with ana-
logue measuring inputs AQ1018 or AQ1019.
❑Harmonics analysis and digital filter setup
[1] Enables the harmonic analysis on the selected phases,
activate the relevant check boxes.
[2] Selects the value of the “Range” parameter of the digital filter.
[3]
Selects the value of the “coefficient” factor of the digital filter.
Example: the value of the VL-N variable fluctuates between 222V
and 228V and it is therefore necesarry to stabilize it. The param-
eters of the digital filter must be set as follows:
• RANGE: the variable has fluctuations within the average value
whose amplitude is equal to ±1,3% of the rated value of the
variable itself (where ±1.3% results from (228-222)/ 2= ±3V,
then ±3*100/231V= ±1.3%; 231V being the rated phase-neu-
tral value of a 400V input). The “range” parameter is the action
range of the digital filter and it is set at a value slightly higher than the
percentage amplitude of the fluctuation: e.g. 1.5%.
❑Digital input working mode setup
[1] Enables digital input A1 (input 1 of the digital input mod-
ule installed in slot A of PQT-90);
[2] Enables digital input A1 working mode: “Gas meter” or
“kWh- meter”.
[3] Set the amount of the input pulse (pulse/m3ex.: if the
value 10 has been set, then 10 input pulses will be required
for the following gas metering: 1m3).
[4] Enables digital input A2 (input 2 of the digital input mod-
ule installed in slot A of PQT-90);
[5] Choose digital input A2 working mode: “Water meter”,
“Day, night tariff of the gas meter” or “kvarh- meter”.
[6] Set the amount of the input pulse (pulse/m3ex.: if the
value 10 has been set, then 10 input pulses will be required
for the following metering: 1m3).
[7] Enables digital input C1 to the function of kWh meter, C2
to the function of kvarh meter;
[8] Set the amount of the input pulse (pulse/kWh, kvarh ex.:
set the value 10: 10 input pulses will be necessary for the
energy metering of 1kWh, 1kvarh). The input pulses C1

• COEFFICIENT: if the new value acquired by the instrument is
within the action range of the filter, then the new displayed value
will result from the sum of the previous value (A) to the variation
(B) divided by the filtering coefficient (C), that is: [(A) + (B/C)]. As
a consequence, a value higher than this coefficient, will result in
a higher settling time and therefore a higher stability. Generally,
the best result will be obtained by setting the filtering coefficient
to a value equal to at least 10 times the value of the range
parameter. In the example above: 1.5*10=15. To improve the
stability, the filtering coefficient can be increased: the admitted
values are within 1 and 255.
❑Setup of min. and max. values logging and relevant variables
This dialog box allows to associate some variables to the
automatic logging of max and min values (from Max. 1 to
Max. 12 and from Min. 1 to Min. 8).
[1] Select the data to be logged activating the relevant
check box.
[2] Select the variable to be logged among those available
in the drop-down list that will appear after clicking on the
arrow on the right of the box.

❑Logging variables selection and dmd power calculation
This window allows the user to enable the variables to be
logged (Max 8) in the data memory of PQT-90 and the work-
ing mode of this operation.
[1] Select the variables to be logged (Max8) activating the
relevant check boxes.
[2] Select if, in addition to the logging of the average values of the
variables, PQT-90 is required to log also the min and max values in
the time interval.
[3] Select the value of the logging time interval (from 1 to 60 min.)
During the measurement, the instrument takes sam-
ples of the selected variables every 200ms approx; at
the expiry of the set time interval, the instrument cal-
culates the average of the samples and carries out the
data logging. The historical value will therefore be guaranteed
to be highly accurate.
[4] Selects the dmd (W-VA-var-PF) calculation method
between FIXED and FLOATING.
FIXED SELECTION: if a value of 15 minutes is selected, the

instrument calculates the dmd value and updates it every 15 minutes.
FLOATING SELECTION: if for example the value “15 minutes” is
selected, the instrument calculates the dmd value and updates
its value at first after 15 minutes and then every minute generat-
ing a window whose width corresponds to 15 minutes and shifts
by units of 1 minute.
The following diagrams show the two working methods.

The measured energy (partial energy) is placed in TARIFF 1
when the time period is from midnight to 8:00, in TARIFF 2
when the time period is from 8:00 a.m. to 8:00 p.m. and
again in TARIFF 1 when the time period is from 08:00 p.m.
to midnight.
The total measured energy is the result of the sum of all the
partial measures as shown in the figure below:
b) the starting point of the first time period is always 24:00
(midnight) and cannot be changed;
c) the starting point of the following period is always the end
hour of the previous time period.
d) the daily loop is closed by setting 24:00 as last hour of the last

The WINTER and SUMMER time periods are con-
ventional seasons mainly used to manage in the
best way the different energy costs during the year.
The reminds at steps a), b), c) d) on page 20 are
also valid for the MULTI TARIFF function.
In the SINGLE TARIFF, only one period exists, referred to the
whole year.
In the DUAL TARIFF, the “year” can be divided into two peri-
ods: whole year and holidays.
In the multitariff, the “year” can be divided into 3 periods:
winter, summer and holidays.

erated by the measured value (“max. input value”). “Min. out-
put value”: value expressed as % of the zero of the output
range (0-20mA, 0-10V, etc.) that is generated by the minimum
measured value (“min. input value”).
Example 1: to measure a consumed power up to 100kW
and retransmit it with a signal from 4 to 20mA, the
module to be used is AO1026 (2x from 0 to 20 mA)
or AO1050 (1x from 0 to 20mA); the instrument is to
be set-up as follows:
• Variable: WΣ(active system power)
• max. input value: 100.0 kW;
• min. input value: 0.0 kW;
• max output value: 100.0% corresponds to 20mA, then:
(100*max. output)/fullscale output=100*20mA/20mA =100%
• Min. output value: 20.0% corresponds to 4mA, resulting from:
(100* min. output) / fullscale output= 100*4mA/20mA= 20%
Example 2: to measure both the consumed power (up to
100KW) and the generated power (up to -100kW), and
retransmit it with a signal from -10 to +10V, the module to be
used is AO1033 (2x ±10VDC) or AO1057 (1x ±10VDC). The
parameters can be setup as follows:
• Variable: WΣ(system active power)
• Max. input value: 100.0 kW;
• Min. input value: -100kW;
• Max. output value: 100.0% corresponds to 10V, then:
(100*max. output)/ fullscale output = 100*20V/20V=100%.
• Min. output value: 0.0% corresponds to -10V, then: (100*
min. output)/fullscale output= 100* 0V/20V= 0%; in this case
also the “total” excursion of the analogue output is to be
considered, therefore from -10V to +10V=20V
As a consequence, when the power is -100kW, the output
will be -10V, when the power is 0, the output will be 0V and
when the power is 100kW the output will be +10V.
Example 3: the whole range of the values admitted for the
variable PF corresponds to values between C 0.00 and L
0.00 (for each phase) which, after retransmission, will be
respectively 0 and 20mA. When PF is equal to 1 (since it is
in the middle of C 0.00 and L 0.00), the output will be equal
to the centre of its scale, that is 10mA. As a consequence,
the instrument is to be setup as follows:
• Variable: PF L1 (or L2 or L3);
• Max. input value: L 0.001: the max input value will correspond to
C if its sign is negative and to L if its sign is positive.
• Min. input value: C 0.000; the min input value will correspond to
C if its sign is negative and to L if its sign is positive.
• Max output value: 100%;
• Min. output value: 0.0%
The min. input value to be set for L is 0.001 to avoid any unde-
sired variations of the analogue outputs.
