    Loop Impedance Meter MZC-306

    Performing loop impedance tests without tripping RCD, saves time and money by not having to take the RCD out of the circuit when testing and is a safer procedure.  It is important to know that if a fault occurs in an electrical installation, sufficient current will flow to operate the fuse or circuit breaker protecting the faulty circuit within a predetermined time. This Loop impedance meter has adequate Cat IV rating up to max 750V and will makes light work of short circuit loop measurements.
