Phase rotation test
L LED
and
R LED
for phase rotation test may operate on various wiring systems,
but effective testing result can be obtained only on three-phase 4-wire system.
Grasp the instrument firmly and connect both probes to the object under test.
(Grasp method shown as below).
Phase-to-phase voltage is indicated by each voltage LED.
R LED
indicates that the field is rotating towards the right direction of the
"probe". With this connection, the motor will go in positive rotation.
Grasp Firmly!!!
L LED
indicates that the field is rotating towards the left direction of the probe. With
this connection, the motor will go in negative rotation.
