Earth resistance and earth resistivity meter MRU-200 WMPLMRU200

The MRU-200 meter uses all known earth resistance measurement methods, which definitely distinguishes it from other devices.

The capabilities of the device are complemented by measurements of soil resistivity, continuity of protective and equipotential bonding and, using clamps, leakage or fault currents.

Allows you to perform measurements:

• earthing resistance with the use of auxiliary electrodes,
• earthing resistance with the use of auxiliary electrodes and clamps (for multiple earthing measurements),
• earthing resistance with using double clamps (for earthing measurements, when it is not possible to use auxiliary electrodes),
• earthing with the impact method (without the need to disconnect the measured earth electrodes),
• ground resistivity (Wenner method),< /li>
• current using clamps (e.g. leakage) and flexible clamps (Rogowski coil)
• fault currents,
• measurement of continuity of equipotential bonding and protective connections (meeting the requirements of PN- EN 60364 - 6-61:2000 point 6.12.2) with auto-zeroing function - current 200 mA.

Additionally:

• measurement of the resistance of the auxiliary electrodes RS and RH,
• measurement of interference voltage,
• measurement of the frequency of the interference signal,
• measurement in the presence of interference voltages in networks with a frequency of 16 2 /3 Hz, 50 Hz and 60 Hz and 400 Hz (with automatic selection of the appropriate frequency of the measurement signal or manual selection),
• selection of the maximum measurement voltage (25 V and 50 V),
• entering the distance between the electrodes for resistivity in meters (m) and feet (ft),
• memory for 990 measurements (10 banks of 99 cells each),
• calibration of the clamps used,
• real time clock (RTC),
• USB and Bluetooth data transmission to a computer,
• battery status indication.

Measurement category: CAT IV 300V (CAT III 600V)
