These modes are displayed when the 3PL is first powered on. If a test is not available based on the type of power input then a
message will be displayed on the screen.
Other 3PL Features:
 The 3PL contains two fuse holders show in side view diagram. These are used to protect the RCD circuitry of the 3PL.
Only replace these fuses with M205 1A ceramic slow blow fuses. Under normal condition these fuse should never have
to be replaced.
 The 3PL uses a thermal fan located on the side of the unit. This operates whenever an earthbond test is performed or if
the unit internal temperature is too hot.
 The 3PL contains an internal thermostat which cuts the power to the unit at 75C. This may be triggered on hot days
when performing many earthbond tests. If the 3PL does not power up, unplug the unit and wait 10-20 minutes to cool
down.
 An RS-232 port is located in the console of the lid. This is for connecting to the Zebra printer VIA a serial cable.
 PS2 keyboard connect is provided to connect a scanner and keyboard.
 A USB port that connects to the PC for uploading, downloading records and general testing.
 3PL allows up to 1000VDC insulation tests. The default is always 500VDC. If the voltage needs to be changed then
please read the change ins in the TnT options section.
