Measuring principle: Stakeless measurement of resistance in closed loops
using two current transformers
Measuring voltage: Um = 48 VAC (primary)
Measuring frequency: 128 Hz (125 Hz on request)
Noise current (Iext): max. Iext = 10 A (AC) (Ra < 20 Ω)
max. Iext = 2 A (AC) (Ra > 20 Ω)
Automatic range selection
The information regarding stakeless ground loop measurements is only valid
when used in conjunction with the recommended current clamps at the
minimum distance specified.
