• The socket is continuously checked for faults. If the "turn plug by 180°" symbol (7) is
displayed on the screen, you are advised to either turn the Schuko-plug or the exchange
the L and N connectors at the instrument.
• If the socket symbol (6) is displayed, a mains error is present. If the voltage present between
N and PE exceeds the preselected contact voltage limit (50V/25V), „UB>UL" (4) is displayed.
• To perform a complete socket test, touch the contact electrode PE (23) and observe the
displayed values on the screen. If the symbol " socket error" (6) occurs, a PE error is
present.
• You are dealing with a PE error, if the error signal is audible and the 'Attention' symbol (1),
and 'Socket Error' (6) are displayed. I.e., either the PE is not connected or a high voltage
(phase) is present at PE.
• The measurement may only be started if the socket is not faulty and the measurement
adapter has been connected by respecting correct polarity.
6) Press the "Start" key (26) to start the measurement. During the measurement ' - ' is
displayed on the screen.
• If a contact voltage UB is generated between conductors N and PE exceeding the pre-
selected contact voltage limit UL, the measurement is interrupted and the 'Attention' (1),
'UB>UL' (4) symbols are displayed on the screen.
• If the contact voltage measured exceeds the 50V or 100V measurement range, the attention
symbol (1) and '>50V' or '>100V' are displayed on the screen..
The trip time tA is displayed in the large result field (12). The measured trip time tA and the
contact voltage with reference to the trip current may be called for display by pressing the
'display' key (21).
• If the RCD trips during the measurement, the symbol for socket error (6) is displayed. If the
RCD already trips during the preliminary test, the "Attention" symbol (1) is displayed in
addition. In this instance, please check whether the correct nominal trip current has been
selected. Possibly, the current preload of the PE is at such a high level that the RCD trips
cirrectly caused by the test, or the RCD itself might even be faulty.
