* Re = 10 MΩ
Overload protection: in 200 mV range: up to 250 V / rms otherwise
up to 1000 V DC / 750 ACpp
** 40-400 Hz, sinusoidal signal
*** Input sensitivity ≤ 200 mV
**** Test signal approx. 400 Hz, 40 mVpp, with capacities greater than
30 µF the displayed value is only a reference value
Capacitance, temperature, frequency, resistance: Overload protected up to
250 V ACrms
Current measuring range:
mA range: fused F0.5 A / 250 V – 20 A range: not fused - measurement in
20 A range. Max. 10 s, then 15 minute break
Accuracy guarantees for a year at a working temperature of 23ºC ±5ºC and
humidity <75%. Temperature coefficient: 0.1 x (accuracy) per 1ºC.
