5.12.3. LEAKAGE CURRENT MEASUREMENT ON SCHUKO SOCKET
Measured quantities and display ranges:
Leakage current I
PE on schuko socket 0.25 mA  10 A
Mains voltage U L/N 195  253 V
1) Select I LEAK measurement by pressing the FUNC hard key first.
2) Select SOCKET mode by pressing the MODE touch-screen key first.
3) Check selected limit leakage current by pressing the LIMIT (5) touch-screen key first. Four
independent limit values are available for quicker operations. Select the closest one and modify it
by using the + and ― touch screen keys if needed.
4) Check selected position of phase terminal on schuko socket by pressing the L POS (6) touch-
screen key. If LEFT position is selected then phase potential is connected to left terminal of schuko
socket and vice versa.
5) Select measurement screen by pressing the touch-screen key and check all settings again.
6) Connect the UUT to schuko socket according to the figure below.

7) Start the measurement by pressing the START/STOP button. The measurement will start to run
and will be stopped after pressing the START/STOP button again. Measurement result will be
currently displayed in green colour if it is lower than or equal to set limit value or in red colour if it is
higher than set limit value. Final result will be equipped with green symbol and with beep-beep
sound if it is OK or wit h red symbol and with longer beep sound if it is not OK . See the display
outlook with test result on the figure 43.
8) Save the test result by pressing the SAVE hard key twice, for further instructions see the
“MEMORIZING EXAMPLE” section.
CAUTION
 Measurement at both phase positions (phase at left terminal and phase at
right terminal) must be carried out and the highest value must be evaluated.
 Switch on the UUT in order total leakage current to be measured!
 In case of overloaded test socket the fuse F1 or F2 (both T16A/250V) may
blow.
 Do not use test schuko socket except for measurement purpose!
 Measurement time (CLAMP and SOCKET) is limited to 60 min!
