[1] Specifications are for 90 minutes warm-up and 1 s gate time.
[2] For frequency ≤300 kHz, the specification is for AC input voltage of 10% to 110% of range. For frequency >300 kHz, the specification is for AC input
voltage of 20% to 110% of range. The maximum input is limited to 750 V rms or 8 x 10
7 Volts-Hz (whichever is less). 200 mV range is full range input
or input that is larger than the full range. For 20 mV to 200 mV inputs, multiply % of reading error by 10.
