The reference signal can be used by multiple 4LSL modules in the s

measuring cycle. An earth leakage can be localized since impedance measuring is
always done in respect to the loudspeaker circuit. When earth leakage is occurring in
the loudspeaker circuit being tested it is detected over the opto-coupler input of the
TG01. Earth leakage is signalled by a red LED on the front plate of the module and
passed to the 4LSL. When impedance measuring by the 4LSL is finished then the
earth leakage LED on the TG01 switches off.
