Input channels
Voltage: 4 channels, ac/dc
Current: 5 channels
Voltage channels
Input resistance: 2 MΩ
Input capacitance: < 20 pF
Current input characteristics
2 V rms = full scale, 1 MΩ Input Impedance for ferro CTs, low impedance for Flexi-CTs
Measuring method
Simultaneous digital sampling of voltage and current. Digital PLL synchronized sampling, internal
frequency reference used during voltage drops.
Synchronization and sampling
PLL-synchronization source
The PLL synchronizes to the A-N voltage for wye power types, and to the A-B voltage for delta
power types. All listed power types can be characterized as either wye or delta.
PLL lock range
42.5 to 69 Hz
Sampling frequency
Voltage and current: 256 samples/cycle
Inter-harmonics per IEC 61000-4-7: 2560 points/10 cycles (50 Hz),
3072 points/12 cycles (60 Hz)
Transient Voltage: 5 MHz
A/D resolution
Voltage and current: 24 bits
Transient voltage: 14 bits
Voltage and current measurements
Voltage measurement range
AC voltage: 1000 V rms ± 10 % over range
DC voltage: ± 1000 V + 10 % over range
Voltage crest factor
3 or less
Current measurement range
Depends on current probe used
Current crest factor
4 or less
Voltage and current measurement accuracy
RMS voltage
Measurement type
True rms calculated continuously: every cycle, every 1/2 cycle, and
every 10 or 12 cycles at 50 or 60 Hz respectively, as required by IEC 61000-4-30.
Measurement uncertainty
AC: ± 0.2 % reading ± 0.1 % full scale, above 50 V rms
DC: ± 0.5 % reading ± 0.2 % full scale, above 50 V dc
RMS current
Measurement type
True rms calculated continuously: every cycle, every 1/2 cycle, and
every 10 or 12 cycles at 50 or 60 Hz respectively, as required by standards
Measurement uncertainty
Ferromagnetic Clamps: ± (0.1 % full scale + 0.2 % reading + current sensor accuracy),
valid for 5 % to 100 % of current sensor range
Flexible Current Probes: ± (0.1 % full scale + 0.5 % reading + current sensor accuracy),
valid for 5 % to 100 % of current sensor range
