"End".
If the measured value is outside the range of the TV 470, the number "1" will
be displayed on the screen.
To evaluate the measurement result LED1 and LED2 can be used to help.

PE conductor resistance measurement (R-PE)

Connect the DUT to the test socket according to Illustration1. Connect one
test lead to the socket "R". To carry out the test, touch all the associated pro-
tective metal parts.
The test can only be carried out with the use of the test leads (Illustration 2).
Connect a test lead to each of the sockets "R" and "GND".
The resistance of the PE conductor from the mains power plug to the metal
parts of the DUT that are touching the PE.
The resistance between the two test leads is determined using these two
leads.
