The MPI-505 meter is a modern, easy and safe measuring device. Please acquaint yourself with the present manual in order to avoid measuring errors and prevent possible problems related to operation of the meter. OPERATING MANUAL MPI-505 version 1.03...
Safety MPI-505 meter is designed for performing check tests of protection against electric shock in mains systems. The meter is used for making the measurements the results of which determine safe- ty of electrical installations. Therefore, in order to provide conditions for correct operation and the cor- rectness of the obtained results, the following recommendations must be observed: ...
