First-level operation directory, through the “←”→” key to select these
functions, when these functions are selected, press the “↑”↓”" key to
select the parameters of the corresponding functions.
Tip: The cursor can quickly jump to the
button
by pressing the "Enter" button under the first-level operating
directory, which can quickly start the measurement.
Product No.
Set the test number for this testing
Rated HV
Rated LV
Set the rated high and low voltage values of the tested products. The
high and low voltage values can be input according to the actual
voltage value, or according to the actual situation, according to the
actual proportional relationship.
Only when the rated high, low voltage, tap spacing and rated
tap input are correct, can the test results correctly calculate the current
tap gear value and error value.
Tap
Set the tap spacing and rated tap of the tested product. For the test
product without tap, the rated tap input is 00 or 01.
Group
Set up the connection mode and connection group of the tested
products
Group
When the user chooses the known connection mode, the
measurement and
display of the instrument are based on the user's input. When the
user chooses the "unknown" connection mode, the instrument
automatically determines the connection mode. If both the high and
low voltage sides choose the "unknown" connection mode, the
measurement results do not show the connection mode. For the
connection group, the user can choose according to the actual
situation. If the connection group is unknown, the user can choose
"automatic", which can be judged automatically by the instrument. In
the menu of "blind measurement function", the connection group is
fixed as "automatic" and can not be changed.
Test method
Choose different ways of measurement..
Three phase ratio: according to the set of high and low voltage
connection mode and connection group, three phase simultaneous
measurement of conversion ratio.
Group test: only measure the join group.
Three-phase AB, three-phase BC, three-phase CA: According to the
set high and low voltage connection mode and connection group, only
for the selected phase ratio measurement.
