connection with neutral lead. For the windings of yn connection, since
difference exists between the three-phase and single-phase measurement
results due to the effect of copper bus connected, single-phase measurement
is recommended.
The three-phase wiring is shown in the figure below:
After the winding under test is wired and the suitable measuring current is
selected, press the “Measure” key-press to allow the tester to enter into its
measuring state and to start to supply power to the winding, and then it enters
into the interface as follows:

At this time, the current of the winding starts to increase. If the charging
progress strip and the current display value stand still for a long time, it
indicates that the value of the resistance value to be measured is probably
beyond the measuring scope of the current, so it is not able to reach its set
