• Four isolated voltage and current input channels are provided to support simultaneous multi-
system measurements such as inverter primary and secondary power.
• Measure power system wiring configurations from single-phase to three-phase, four-wire.
• Broad frequency range (0.5 Hz to 5 kHz fundamental) supports DC to inverter frequencies.
• Basic accuracy is ±0.04% rdg. ±0.05% f.s. at DC and from 0.5 Hz to 200 kHz.
• Precise measurements over a broad range of inverter carrier frequencies: ±0.2% rdg. ±0.1% f.s.
at 10 kHz, and ±1.5% rdg. ±0.5% f.s. at 100 kHz.
• This function utilizes virtual oversampling, a new technology, to correct current sensor phase
errors at a resolution of 0.01
, allowing accurate measurement of the high-frequency, low-
power-factor power components contained in inverter output switching frequencies.
• While maintaining high accuracy, power measurements and harmonic analysis updates every
50 ms.
• During low-frequency measurements, data is automatically updated in sync with frequency, so
no refresh (data update rate) switching is needed when changing from low to high rotation
rates.
• Simultaneously measure RMS, mean, AC and DC components, and fundamental waveforms.
• Perform harmonic analysis up to the 100
th
order and inverter noise (FFT) analysis up to 200
kHz.
• Display high-speed waveforms sampled at up to 500 kS/s.
• Perform multifaceted analysis with X-Y graph functions.
• Simultaneously analyzes harmonics, noise while performing integration, displaying waveforms
and trend graph.
• Select from various AC and AC/DC clamp-on current probes with ranges from 20 A to 1000 A.
• Measure high currents with high precision using clamp-on current sensor probes.
• Clamp-on current probes eliminate the need for problematic direct contact with wiring.
• In-phase effects on inverter measurements are greatly reduced by isolating current sensors
from the measurement objects.
