• Maximum allowable voltage: 750 Vrms, or 1100 Vpeak (continuous), however DC content are
±500 V or less.
• An input attenuator is the case when 100 mV to 750 V range of ACV is switched automatically
or manually.
• An input range is 100 mVrms to 750 Vrms at 3 Hz to 100 kHz.
• However up to maximum 2.2×10
7
[V·HZ] in 100 kHz to 300 kHz
• An input 200 Vrms or more guarantees up to 100 kHz.
• In the input 3Hz or less and more than 300 kHz, measuring and display may be performed but
it is out of accuracy guarantee.
