    Electrical Installation Multi-function Meter - Overview

    The Electrical Installation Multi-function Meter MPI-530 is an instrument for electric shock protection measurements. It includes the option of various  earthing and earthing resistance measuring methods. Additionally, the meter enables its user to analyse power supply parameters, and record and display them on its screen. The instrument automatically measures the insulation resistance in a socket and 3 -, 4 - and 5-wire cables when used with an AutoISO-1000C adapter. Measurement results may be continuously verified, depending on the user’s demand or according to binding regulations. The memory of the instrument may store tens of thousands of measurements allowing users to store them in a structure of a protocol and describe individual measurement points.
