6 Setup PQTSoft Remote 7 Setup PQTSoft Remote ■ PQTSoft Remote in brief PQTSoft Remote has been conceived to program PQT-90 by means of a data transmission from the PC to the instrument via RS232 or RS485 serial interface. The choice between one interface or the other is therefore very important for the correct operation of the instrument as shown by the following figure: Local single PQT connected to the PC by RS232 serial port RS232 SIU-PC ...

The following windows will vary according to the modules selected in the box “Instrument composition...” (see previous page). ❑ Instrument working mode, clock and system setup 1 7 PQTSoft Remote 3 5 6 6 [1] Enables the energy metering.
12 Configuration PQTSoft Remote ❑ Digital input working mode setup 13 Configuration PQTSoft Remote and C2 are not available if PQT-90 is supplied with analogue measuring inputs AQ1018 or AQ1019. ❑ Harmonics analysis and digital filter setup [1] Enables the harmonic analysis on the selected phases, 1 4 2 3 6 5 7 1 8 [1] Enables digital input A1 (input 1 of the digital input module installed in slot A of PQT-90); [2] Enables digital input A1 working mode: “Gas meter” or “kWh- meter”.
14 Configuration PQTSoft Remote • 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.
16 Configuration PQTSoft Remote ❑ Logging variables selection and dmd power calculation PQTSoft Remote 17 Configuration 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 generating a window whose width corresponds to 15 minutes and shifts by units of 1 minute.
