Megger PSI410 Manuel De L'utilisateur page 3

The PSI410 also features a triple dual coloured LED display that indicates that all three
phases are present.
INSTRUCTIONS
As both croc clips and prods are supplied with the unit, select the preferred method of
the connection and connect to the test leads. The croc clip option will allow isolation of
the supply during connecting and disconnecting the test leads.
The dual coloured LED display at the top of the PSI410 indicates the state of each of
the connected phases with a green coloured LED indicating the phase is present while
a red coloured LED shows a missing phase connection. This feature enables a graphic
display of a good connection when using the test prod option and will indicate a phase
which has a substantial lower voltage than the other two phases.
Connect the test leads following the circuit's applicable cable colour code and once
all three phases are connected observe the direction of rotation and colour on the
sequencing LED display on the PSI410.
Clockwise rotation is indicated by clockwise rotating green LEDs with a continuous tone
and counter clockwise rotation has counter clockwise rotating red LEDs and a warbling
tone. If a failure of the rotating displays is observed then check the test lead connection
while monitoring the phase status LEDs.
The unit is for intermittent use only and must not be permanently connected to the
supply.
