Sonel presents MPI-502 multifunctional electrical installations meter.
It is useful in measurement of short circuit loop impedance in networks having rated voltage of 220/380V, 230V/400V, 240/415V and frequency of 45 to 65Hz. It is also used for measuring short circuit loop impedance with 15mA current without circuit breaker tripping.
MPI-502 can be used for testing of AC, A type RCD breakers. It can be used in testing of prompt, general (short-delay) and selected RCDs for 10, 30, 100, 300, 500mA of rated current values. It can also be used in measurement of IA. It is useful in measuring RE and UB without circuit breaker tripping. The MPI-502 also serves in expanded RCD test function AUTO with ZL-PE measurement and 15mA current. During one RCD tripping, it is useful in measuring IA and tA.
Additionally, MPI-502 is capable of detecting automatic conversion in the meter and replacement L and N in the socket. It is used in protective circuits and junctions for low voltage resistance measurement. It is useful in measuring resistance having 200 mA current. It also serves in test leads calibration and allows the use of any length of test leads.
