[1]. This specification will be available after 60 minutes of warm-up and
sine wave input, unless stated otherwise. This specification applies to 1s
gate time.
[2]. This specification is available when both sine wave and square wave
input ≥ 100 mV. For the input of 10 mV to 100 mV, the % of reading
error needs to be multiplied by 10 times.
[3]. The amplitude range is from 10% to 120% and is lower than 750
VAC.
[4]. The input ≥ 60 mV, for 300 k to 1 MHz, within 100mV range.
