Transformation
ratio
Three
kinds
of
transformation
ratios:(
actual
measurement
of
primary/secondary
circuit;
transformation on the basis of secondary circuit bearing
current 5A; transformation on the basis of 10kV-YY of
10kV/380V transformer and the Max. ratio is 1:10 million
(1.0K7)
Data storage
3,000 sets, press HOLD to hold the data ,number and
store automatically(power failure or battery replacement
will not cause data missing)
Line voltage
Test for lines bearing voltage below 60kv (insulating rods
with five knots must be used)
Data hold
Press HOLD to hold the data, and sign of
“Hold”
appears; press it again, holding will be canceled.
Data search
Press HOLD and POWER to enter the mode of data
search.
Overflow display
Outrange overflow: “OL A” appears
No signal
instruction
When the main engine does not receive transmit signals,
present “No Signals”
Automatic
shutdown
15 minutes after starting up, the tester will shutdown
automatically
