Recordings • 4MBytes removable flash card memory for data storage • • WCAP option - advanced waveform capture function oncurrents and L-N voltages. The instrument can store up to 10 + 200 waveforms before and after a threshold overcome, with a resolution from 8 to 32 samples (depending on the number of waveforms). The WCAP option includes a second selectable function: Min/Avg/Max values calculation and recording (see previous paragraph) Up to 10 programmable recordings with different start andstop time. Different type of recordings can be chosen:-import/export active, reactive and apparent powerdemand with programmable average time. The average period can be syncronized by a digital input-instantaneous read values selected between the mainparameters. The recording interval time is programmable between 1 and 9999 seconds-instantaneous min/max values measured during therecording interval time. The recording interval time is programmable between 1 and 9999 minutes-voltage and current harmonic values measured duringthe recording interval time. The recording interval time is programmable from 1 to 60 minutes • The CPU2 option includes 1MBytes non-volatile datamemory. Depending on the CPU2 configuration the following information (already described in the “Power Quality” paragraph) can be recorded:-sags and swells events (VDROP option). The occurringdips and overvoltage over a programmable threshold are detected and the instrument records the date and time of the event, the lenght and the RMS value of 100 +100 half-cycles before and after the event-min / avg / max values of the main measured parameterswith continuous sampling and 1 cycle minimum • Event, alarm and digital outputs ON/OFF recording. Theinstrument records the status change of 8 programmable set points, the digital outputs ON/OFF and the instrument supply ON/OFF. All the events are integrated by date and time reference • Time-of-Use (TOU) programmable data recording. TheTOU function stores the energy consumption in different registers according the programmed time-scheme. A group of 120 registers give the situation of the previous and current day, and of the previous and current month. This feature is designed to fit different tariff structures. It’s possible to program up to 10 daily tariff schedules containing up to 3 tariffs and 8 tariff changes. Eachschedule can be assigned to the days of the week andmonths as requested. Up to 20 holidays can be assigned to the lowest tariff. A diagnostic algorithm checks and notifies any setup overlapping.

Main Features

Measurements • Three-phase 3-wire or 4-wire unbalanced load operation,single-phase and direct current. • Direct measurement up to 600 (750)V
AC • The instrument can accept different signals from any typeof measuring transducer, including flexible Rogowski transducers. The required current channel type is easily selectable by the instrument menu. This flexibility allows to connect the following current tranducers:-voltage output manufacturers of clamps (1, 2, 3V
AC-DC full scale)-current output clamps (1, 5A
AC full scale)-Rogowski flexible clamps (40 or 100mV/kA)-direct insertion up to 600V
AC (1, 5, 20A
AC full scale)-current tranducer signals (1, 2, 3, 10V
AC-DC full scale) • A fourth current input is also provided specifically for themeasurement of earth leakage current • True RMS metering provides accurate measurement evenby distorted waveform • • Fully bi-directional, four-quadrant readings. 10 energycounters are available, the apparent power/energy is splitted in four counters: import lagging, import leading, export lagging, export leading Volts, Amps, Power, PF, Frequency, Energy, Min/Maxvalues, Demand, Harmonics, etc. The full version instrument provides more than 600 measured/calculatedparameters and shows on the LCD more than 30 graphicalpages Power Quality • Individual & total harmonic distortion for voltage and currentup to the 50 • VMAX option - two functions are selectable: VDROP(previous paragraph) and Min/Avg/Max values calculation and recording with one cycle resolution (20ms @ 50Hz). This function allows to record up to 10 parameters selected among voltage, current, power, PF and frequency. The datais viewed on the PC according EN50160 standard. • VDROP option - sags & swells detection on L-N voltageswith half cycle resolution (10ms @ 50Hz). Pre- and post- trigger logging (100 +100 half cycles RMS values). The detected events are recorded and a relay output can be activated when a voltage anomaly occurs. The data is viewed on the PC according EN50160 standard.
th order. The harmonic content is representedlike even, odd and total • CPU2 option - the co-processor board perfoms thesimultaneous high-resolution sampling of voltage and current, allowing the cycle-by-cycle power analysis for 50/60 Hz lines. The CPU2 board supports different application like: VDROP, VMAX, WCAP... (see below). The instrument with CPU2 board performs at the same time the wattmeter functions, the harmonic analysis, the basic recording function and the selected cycle-by-cycle power analysis function.
