Input
Standard DC current signals in the range 0…20 mA.
The current signal is detected by a 50 Ω shunt, which is manually connected
through an internal jumper.
DC voltage signals in the range 0…250 VDC.
By measurement of AC current signals up to 1 A from a current transformer or
current clamp a 1 Ω / 2 W input shunt is used.
True RMS measurement of AC voltage signals in the range 0…250 VRMS, with a
crest factor < 5.
