(Rated range)
The maximum rated range is 600 V for the voltage input terminal and 20 A for the current
input terminal.

(Rated range)
The “maximum rated range” is 10 V for option /EX1 and 200 mV for option /EX2 (twice
these values when the crest factor is set to 6).
Except, at least 0.01%. The unit of frequency f is kHz.
Line filter See “Voltage, Current, and Active Power Measurement” in section 16.3, “Functions.”
