Note 1:
The waveform displayed by the instrument is the collected gear signal, so do not
use the waveform amplitude to determine the size of the data.
Note 2:
No PT measurement, fixed UI angle = 83.5 degrees, easy to calculate resistive
current
。

wiring points
1.1Take full current: Single-phase MOA is connected to A (yellow) channel, and the three
phases are connected to A (yellow) B (green) C (red).
1.2 There is a fuse on the wire connecting the PT voltage. Do not replace it with fuses or
wires of other specifications.
1.3 The instrument can only be used for low voltage and low current tests. All leads must
be kept away from high voltage.

Three-phase measurement:
Three-phase cable voltage, plus extension cable
connection is to connect the opposite connector of the extension cable between “host”
and “voltage PT connector”.
