Function Sensitivity (ACrms) Range
mV 300mV 10Hz - 125kHz
5V 2V 10Hz - 125kHz
50V 20V 10Hz - 20kHz
500V 80V 10Hz - 1kHz
1000V 300V 10Hz - 1kHz
Ω, Cx, diode 300mV 10Hz - 125kHz
µA, mA, A 10% F.S. 10Hz - 125kHz
FREQUENCY
Accuracy: 0.01% + 2d
Accuracy Notes: Accuracy is ± (% reading digits + number of digits), or as otherwise
specied, at 23ºC ±5ºC < 75% R.H. True RMS accuracies are specied from 5% to 100% of
range or as otherwise specied. Maximum Crest Factor <3:1 at full scale & <6:1 at half scale
(with frequency component within the specied 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
Digital Display: 5000 count LCD display; 5 per second nominal refresh rate

Datalogging Capacity: 43000 points
Datalog Sample Rate: 0.05 (0.2 for ºC/ºF & Ω, 0.4 for Hz and 1 for C), 1, 20, 40, 60,
120, 240 & 480 seconds
Low Battery: Below approx 7V
