Full-scale reading: 9999 counts

Accuracy: ± (0.5 % + 2 counts)

Voltage/Herz ratio (V/Hz)

Purpose: To show the measured V PWM value (see V PWM) divided by the fundamental frequency on vari- able ac motor speed drives

Accuracy: % Vrms + % Hz

Voltage unbalance drive input

Purpose: To show the highest percentage difference of one of the phase vs average of the 3 true-rms voltages

Accuracy: Indicative percentage based on Vac+dc values

Voltage unbalance drive output and motor input

Purpose: To show the highest percentage difference of one of the phase vs average of the 3 PWM voltages

Accuracy: Indicative percentage based on V PWM values

Current unbalance drive input

Purpose: To show the highest percentage difference of one of the phase vs average of the 3 AC current values

Accuracy: Indicative percentage based on Aac+dc values

Current unbalance drive output and motor input

Purpose: To show the highest percentage difference of one of the phase vs average of the 3 AC current values

Accuracy: Indicative percentage based on A ac values

Rise and fall time Readings: Voltage difference (dV), time difference (dt), voltage vs time difference (dV/dt), overshoot

Accuracy: As oscilloscope accuracy Harmonics and spectrum

Harmonics: DC to 51st

Spectrum ranges: 1…9 kHz, 9-150 kHz (20 MHz filter on), up to 500 MHz (voltage modulation)

Shaft voltage

Events/second: Indicative percentage based on rise and fall time (Impulse discharges) measurements

Report data capture

Number of screens: Typical 50 screens can be saved in reports (depends on compression ratio)
