Direct Measuring Method
– Permanent connection measurement type (P1)
– Permanent connection
– Probe to P1 terminal
Schematic Diagram
Patient leakage current is measured between the protective extra-
low voltage terminals and PE at the mains connection.

Test Sequence
➭ Set the rotary switch to the I
P
position.
➭ Connect the DUT to the test socket.
➭ In the case of direct measurement, measurement must
be performed with mains plug polarity in both direc-
tions. Select the respective polarity to this end by
pressing the NL/LN key.
➭ Start the test: press the START/STOP key.
➭ After each reconnection to the mains, and as soon as
the first test is started, a mains connection test is exe-
cuted.
➭ Acknowledge the warning which indicates that line
voltage will be connected to the test socket.
➭ Contact the short-circuited inputs for the applied parts
with test probe P1.
➭ The measured values are displayed. The measured
value recording symbol shown at the right appears.
Each time this key is pressed, the currently displayed
measured value is saved to the buffer.
➭ Stop the test: press the START/STOP key.
The save symbol appears (floppy disk showing the
number of measured values stored to buffer memory)
and prompts you to save the measured values to an ID
number.
➭ Read the measured values and compare them with the table
of permissible limit values.
➭ Press the ESC key in order to discard the measured
values stored to buffer memory and acknowledge by
pressing the key shown at the right.
