display whether it’s positive grounding or negative grounding; If it's ungrounded,
it displays 999.9KΩ.
3. Open up ground-fault locator, LCD will display related parameters. If the
battery voltage is under voltage, it means the instrument's battery has no power
and needs to charge. Connect the charger's AC220V power supply, insert the
charging plug into charging jacks, after 3 hours' chargement the lithium battery
can be used again. This instrument's power is supplied by lithium battery, the
voltage will gradually decline in the process of using. When the voltage gets
down to less than 10.8V, buzzer alarm will output all along, which means the
instrument can not work, at the moment, we need to charge the battery; at the
same time, the interface prompt that 'synchronizing signal is shaking hands'.
Place the transmitter's 'bus-bar/by-pass' switch on 'by-pass', the receiver shows
'Synchronizing signal shake hands successfully; Transmitter, receiver, please
keep current status'. Whichever reboot or change status will makes receiver get
close to transmitter (reset by-pass) so that synchronizing signal shake hands
again.
4. Use the detection probe of ground-fault locator to lock each by-pass of
DC system, the LCD will show the value of the resistance to ground of current
by-pass and we advise each loop should be detected for 2-3 times to get a stable
value.
5. When using the detection probe to seek by-pass ground-fault, you can
lock the two feeder lines (both positive and negative ones) at the same time, by
only once, you can detect if there is ground-fault on this by-pass. You can also
