Terminal block / Terminal for mains cord
The supplied mains cord can be connected to this terminal.

Terminal block / L/N terminal
This terminal wired in parallel to two short-circuited Phase terminals at the
test socket (1).
The DUT Phase conductors can be connected to this L/N terminal and
measured, if the DUT is not equipped with a mains plug.

Terminal block / PE/2mA terminal
Contact current at exposed conductive parts which are not connected with
protective conductor can be measured by connecting RPE-Test Lead. In
addition, this terminal is wired in parallel to the protective conductor
terminal at the test socket (1), so the DUT protective conductor can be
connected to this terminal, if the DUT earth terminal is not equipped with a
mains plug. Beyond this, exposed conductive parts at the DUT must be
connected to this terminal for insulation testing and the measurement of
equivalent leakage current.

Terminal block / RPE-Test Lead terminal
RPE-Test Lead for resistance measurement of the protective conductor can
be connected to this terminal, and the alligator clip is to be connected with
the enclosure of the DUT.

LED for threshold value
The red LED lights up when limit values defined in the applicable standards
have been exceeded during the measurement of protective conductor
resistance, insulation resistance, equivalent leakage current and contact
current.

NULL button
NULL setting shall be done before starting the measurement of protective
conductor resistance. (Cancel the resistance of the Test Lead, inside
protective fuse and so on.)
