4.5.2 Current measurement
Set the function switch to the I and/or I~ position and the selec-
tor switch for the current ranges to the range corresponding to the
measured value. The selector switch for the voltage ranges may be
set to any position.
Connect the current path to terminals I* (1) and I (3). Read the mea-
sured value off the scale corresponding to the measuring range
and multiply it by the factor of 0.01 (see table in chapter 5 „Specifi-
cations“).
4.5.3 Phase sequence indication
Set the function switch to the position.
Connect all of the 3 outer conductors in proper sequence to termi-
nals L1 (2), L2 (5) and L3 (8).
With correct phase sequence, the pointer deflects up to the mark-
ing (83 % of full deflection), with incorrect phase sequence up
to the marking (17 % of full deflection).
The interlinked voltages must be > 30 V and must not exceed 650 V.
The connected voltages may deviate from each other by a maxi-
mum of 5%.
