    Electrical work on commercial and industrial installations often
    requires working on motorised machinery with three phase
    supplies. Correct sequence of the phases is important with
    certain motors and pumps as damage to brakes and valves will
    occur in minutes with incorrect phasing.
    The Megger PSI410 phase rotation indicator provides rapid
    indication of correct phase sequence utilising a three bi-
    coloured LED display and a specific audible tone. 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.
    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.
    The PSI410 also features a triple bi-coloured LED display
    that indicates that all three phases are present. A green LED
    indicates the phase is present while a red LED shows a missing
    phase connection.
    The unit has a tough rugged case designed for an industrial
    environment and is supplied with long fused test leads with
    croc-clips and prods. The prods have insulated tips that
    provide less than 4 mm exposed tip.
    The PSI410 is self powered from the supply and requires no
    batteries.
