MEASURING SINGLE PHASE POWER (PHASE-NEUTRAL)
Set the connection type selector on the rear panel to 1ø (SINGLE-PHASE). Use only the instrument’s L1 phase inputs
(current to connector L1 and voltage between connectors L1 and N) as show in fig. 4.4.

AC / DC MEASUREMENTS
When taking measurements from DC circuits or networks, or circuits where alternating signals have direct components
superimposed (e.g. inverters, U.P.S., rectifiers), use the Hall effect clamp meters designed for these applications which
are available from the ELCONTROL ENERGY accessories catalogue. Use the ADAPTA-1V/1V adapter (code
4AACQ) for connections to the MICROVIP3 PLUS as shown in fig. 4.5 for the phase L1 inputs and in figs. 4.6 and 4.7
for three phase systems (taking care to ensure that voltage and current inputs correspond).

When either option Std1 or Std2 is selected, the clamp meters can be connected in either direction since the
MICROVIP3 PLUS automatically inverts current direction if necessary.
