0.75/1.5/3/5/7.5/15/30/50/75/150/300/500 V (crest factor CF6A)

+ Current: Direct input:500 mA, 1 A, 2 A, 5 A, 10 A, 20 A, 30 A (crest factor CF3),250 mA, 500 mA, 1 A, 2.5 A, 5 A, 10 A, 15 A (crest factor CF6),250 mA, 500 mA, 1 A, 2.5 A, 5 A, 10 A, 15 A (crest factor CF6A); External current sensor input: 50 mV, 100 mV, 200 mV, 500 mV, 1 V, 2 V, 5 V, 10 V (crest factor CF3), 25 mV, 50 mV, 100 mV, 250 mV, 500 mV, 1 V, 2.5 V, 5 V (crest factor CF6), 25 mV, 50 mV, 100 mV, 250 mV, 500 mV, 1 V, 2.5 V, 5 V (crest factor CF6A)

Input impedance: + Voltage: 10 MΩ ±1%//approx. 15 pF

+ Current: Direct input: 6.5 mΩ ±10% + approx. 0.3 μH, External current sensor input: 1 MΩ ±1%//approx. 50 pF

Instantaneous maximum allowable input (within 1 s):

+ Voltage: Peak value of 2.5 kV or RMS value of 1.5 kV, whichever is less

+ Current: Direct input: Peak value of 150 A or rms value of 50 A, whichever is less; External current sensor input: Peak value 10 times the range or 25 V, whichever is less

Continuous maximum allowable input:

+ Voltage: Peak value of 1.6 kV or RMS value of 1.5 kV, whichever is less; If the frequency of the input voltage exceeds 100 kHz, (1200 – f) Vrms or less. f is the frequency of the input voltage in units of kHz;

+ Current: Direct input: Peak value of 90 A or rms value of 33 A, whichever is less; External current sensor input: Peak value 5 times the range or 25 V, whichever is less

Maximum rated voltage to earth (DC to 50/60 Hz):

+ Voltage input terminal: 1000 V CAT II

+ Current input terminal: 1000 V CAT II

+ External current sensor input connector: 1000 V CAT II

Influence of voltage to earth: When 1000 Vrms is applied between the input terminal and the WT5000 case with the voltage input terminals shorted, current input terminals open and external current sensor input terminals shorted, 50/60 Hz: ±0.01% of range or less.

A/D converter: Simultaneous conversion of voltage and current inputs, Resolution: 18 bits, Sample rate: 10 MS/s max.

Measurement frequency bandwidth: DC, 0.1 Hz to 2 MHz
