Wiring and notice: When using the tester, please follow the
instructions.
1. The ground terminal or the ground wire in the power cable
should be grounded reliably.
2. Please note that the four-color test wires at the high-voltage
side in yellow, green, red and black correspond respectively to
the transformer A, B, C, N terminals. The three-color test wires
at the low-voltage side in yellow, green and red correspond
respectively to the transformer a, b, c, n terminals. Be sure to
make correct connections.
3. When testing the Scott transformer, the high voltage side is
the same as the above, low-voltage side a, β, n correspond to a,
b, c terminal.
For single-phase transformer, high-voltage side A, X correspond
to A, C terminals, low-voltage side a, x corresponds to a, c
terminals.
4. For general Y / y, Y / d, D / d, D / y, ZN / y, ZN / d normal
connection group measurements, connection to the neutral point N
terminal is not needed. For single-phase transformer measurements,
please use the yellow, green test clips at high-voltage side and
the yellow, green test clips at low-voltage side.
5. Please enter correct setting parameters before test. The group
label and the measured transformer must be consistent. If not
sure, choose unknown to be measured by the tester automatically.
6. If you the rated ratio is not put in, results only show the
measured ratio value, and do not show the error.
