|
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 shut down automatically
|
|
Battery voltage
|
When battery voltage is below 4.8v, signs will remind you of replacement
