Sonel MZC-306 Loop Impedance Meter

The Sonel MZC-306 Loop Impedance Meter can measure fault loop impedance to a resolution of 0.01Ω and can determine low-current impedance measurements in circuits protected by RCD ≥30mA (100 to 440V). In addition to this, the Sonel MZC-306 Loop Impedance Meter delivers the following:

• Voltage measurements up to 750V AC (up to 250V with a resolution of 0.1V)
• Calculation of fault current
• Measurements with swapped L and N conductors
• Measurements of resistance (RS) and reactance (XS) components
• Automatic differentiation between phase and phase-to-phase voltage
• Checking the connection of PE terminals using a contact electrode

1.2m, 5m, 10m and 20m test leads or a power network plug adapter can be connected to the Sonel MZC-306 Loop Impedance Meter. Up to 990 readings can be saved to the Sonel MZC-306 Loop Impedance Meter’s integrated memory. Stored data can be transferred via a USB interface.

Support for a wide range of operating voltages (100V to 750V) means the Sonel MZC-306 Loop Impedance Meter can be used to determine measurements for an array of network types. This makes the Sonel MZC-306 Loop Impedance Meter suitable for use in homes, public buildings and facilities, and small workshops and factories. The Sonel MZC-306 Loop Impedance Meter also has an operating frequency of 45 to 65Hz.  

The Sonel MZC-306 Loop Impedance Meter is a versatile, lightweight and professional fault loop meter.
