6.6. LOW10A: CONTINUITY TEST WITH 10A TEST CURRENT (GSC57 ONLY)
WARNING
Before carrying out the continuity test make sure that there is no voltage at the
ends of the conductor under test.
Turn the switch on LOW 10A position.
This key permits to select one of the following measuring modes (which can
be shown cyclically when pressing the key):
"RMEAS" mode: the instrument measures the Resistance value of the
Protection conductor ("Low Voltage Switchgear and control gear
assemblies")
"VDROP" mode: the instrument measures the Voltage Drop and the
resistance across the Protection conductor ("Electrical equipment of
machines")
WARNING
If the resistance is lower than 0.45 (including the test leads resistance) the
continuity test is executed by the instrument with a test current higher than
10A. If the resistance is higher than 0.45 the continuity test is executed by
the instrument with a current lower than 10A.
