INTRODUCTION
The Megger PSI410 phase rotation indicator provides rapid indication of correct phase
sequence utilising a three dual coloured sequencing LED display and a specific audible tone.
To avoid the display rotating at the supply frequency the unit has been designed to
provide a slow rotational speed of the display to allow easy indication of rotation.
Dual phase colour coding has been adopted for the PSI410 to allow ease of use on
both Brown / Black / Grey and Red / Yellow / Blue colour coded supplies.
