Accuracy: 0.01% + 2d
Accuracy Notes: Accuracy is ± (% reading digits + number of digits), or as otherwise
specified, at 23ºC ±5ºC < 75% R.H. True RMS accuracies are specified from 5% to 100% of
range or as otherwise specified. Maximum Crest Factor <3:1 at full scale & <6:1 at half scale
(with frequency component within the specified frequency bandwidth for non-sinusoidal
waveforms).
Audible Continuity: Measurement threshold: Beeper will sound if measurement is below
20Ω. Beeper will not sound if measurement is above 200Ω. Beeper may or may not sound
if measurement is between 20 and 200Ω. Response time: <100µs
