2.3.2 Current Input Wiring
AcuDC 240 meter current can be wired in three different ways: direct wiring, wiring using
a shunt and wiring using a current Hall Effect sensor.
NOTE: When wiring using a shunt or Hall Effect Sensor these must be wired on the
negative terminal of the load that is being measured.
Choice of wire current input is AWG15-16 or 1.5-2.5 mm2 or equivalent resistance wire.
