When adopting CVT self-exciting measurement, the instrument should
measure C
1
firstly and then C
2
with the method of lead measurement and
correct impact of voltage division automatically. It should be noticed that the
HV cable should be hung in the air; otherwise additional dielectric loss to the
ground will cause errors. It is feasible to connect the HV socket and CVT with a
fine cable and suspends them.
It is strongly recommended that black Cx
cable should be used to connect with the HV socket.
3. Additional function
3.1 When the cursor is at voltage:
10kV,
press “OK” key and an
icon
will appear on left bottom of instrument screen. It means that it will print
automatically after testing. Press the OK key again, the icon will disappear. It
means that it must be printed manually after testing.
3.2 When the cursor is at
variable frequency.
under the circumstance of
GST, I-CN and I-UN, press OK key and an
icon will appear on right
bottom of instrument screen. It means that the reverse wiring low voltage shell
testing will begin. Press the OK key again the icon will disappear. It means that
GST low voltage shell is removed.
3.3 When the cursor is at
GST
, press OK key means testing the printer
and change paper.
3.4 When the cursor is at
start
, press DOWN key means taking out the
stored data.
3.5 After finishing test, press
DOWN key
means storing test data.
