Level output 5 Vf.s.(STD.5):±5 V DC at full scale (f.s.), linked to display updates
High-speed level output 2 Vf.s.(FAST.2):
±2 V DC at full scale (f.s.), linked to synchronization interval
High-speed level output 5 Vf.s.(FAST.5)
±5 V DC at full scale (f.s.), linked to synchronization interval
Waveform output 1 Vf.s.(FAST):1 V f.s. at full scale, linked to sampling
Available selections vary with the output parameter.
Voltage, current, active power
Select from: STD.2/ STD.5/ FAST.2/ FAST.5/ FAST
However, specifying FAST.2 or FAST.5 forcibly sets the rectifier to AC+DC.
Apparent power, reactive power, power factor, phase angle, total harmonic voltage
distortion, total harmonic current distortion, voltage ripple rate, current ripple rate,
voltage crest factor, current crest factor, time average current, time average active
power, maximum current ratio
Select from: STD.2/ STD.5
Frequency, current integration, active power integration
fixed to STD.5
Full scale (f.s.) for the above parameters is as follows:
Voltage, current, active power, apparent power, reactive power, time average current,
time average active power:
measurement range
For time average current or time average active power, setting
to TOTAL range causes current measurement range to be set
to 20 A, and power measurement to voltage range × 20 A.
Power factor: ±0.0000 (±1.0000: DC0 V)
Phase angle: ±180.00°
Voltage ripple rate, current ripple rate, total harmonic voltage distortion, total harmon-
ic current distortion: 100.00%
Voltage crest factor, current crest factor:10.000
Maximum current ratio:10.000
Frequency: Selected from the following:
0.5 Hz/ 5 Hz/ 50 Hz/ 500 Hz/ 5 kHz/ 50 kHz/ 500 kHz
Current integration, active power integration:
Selected from the following:
5 m/ 50 m/ 500 m/ 5/ 50/ 500/ 5 k/ 50 k/ 500 k/ 5 M/ 50 M/
500 M/ 5000 M [Ah/Wh]
Error output: Level output of approx. ±9 V DC is generated when the output parameter
display is [o.r] or when the PEAK OVER U or PEAK OVER I lamp lights up.
Output of 0 V is generated for [- - - - -] (invalid data display).
