5. Nastavitev

5.1. Namestitev in polnjenje baterije

The MPI-536 is powered by an internal rechargeable battery. Ensure the battery is fully charged before initial use. Connect the provided power adapter to the meter's charging port and to a suitable power outlet. The charging indicator on the meter will show the charging status.

5.2. Priključitev merilnih vodnikov

Carefully connect the appropriate test leads and probes to the input terminals of the MPI-536 meter. Ensure all connections are secure and free from damage. Refer to the specific measurement section for correct lead configurations.

6. Navodila za uporabo

The Sonel MPI-536 offers a wide array of measurement functions. Navigate through the menu using the meter's controls to select the desired test. Always ensure correct connections and settings for each measurement type.

6.1. Merjenje izolacijskega upora

The MPI-536 can measure insulation resistance up to 2500 V. This function is critical for assessing the condition of electrical insulation in cables, motors, and other equipment.

• Postopek: Select the insulation resistance test mode. Connect the test leads to the circuit or component under test. Ensure the circuit is de-energized and isolated before applying test voltage. Initiate the measurement. The meter will display the resistance value and can generate diagnostic graphs (R(t)/U(t), R(t)/I(t), U(t)/I(t), I(U)) for detailed analysis.
• Napredna diagnostika: The meter automatically calculates absorption coefficients (DAR, PI) and temperature coefficients, which are vital for evaluating insulation degradation over time.
• Automatic Cable Testing: With the optional AutoISO-2500 adapter, the meter can automatically test insulation resistance of multi-core cables.

6.2. Residual Current Device (RCD) Testing

The meter performs comprehensive RCD tests in accordance with relevant standards, including automatic test sequences.

• Postopek: Select the RCD test mode. Connect the test leads to the RCD-protected circuit. Choose the RCD type, rated current, and test current multiplier. The meter can perform tests in 'Auto' mode, executing a sequence of measurements (e.g., trip time, trip current) automatically.

6.3. Earth Resistance Measurement

The MPI-536 supports four methods for earth resistance measurement, along with soil resistivity measurement.

• Metode: Includes 3-pole, 4-pole, two-clamp, and three-clamp methods. Select the appropriate method based on site conditions and requirements.

6.4. Short Circuit Loop Impedance

Measures the impedance of the fault loop, essential for verifying the effectiveness of overcurrent protective devices.

• Postopek: Connect the leads to the live, neutral, and protective earth conductors. The meter can perform tests in circuits protected by RCDs without tripping them.

6.5. Continuity of Protective and Equipotential Bondings

Verifies the low resistance path of protective conductors and equipotential bonding conductors.

• Postopek: Use the continuity test function to measure resistance between protective conductors and exposed conductive parts.

6.6. Other Measurements

• Merjenje jakosti svetlobe: For assessing illumination levels.
• Phase Sequence Test: To verify the correct rotation of phases in three-phase systems.
• Motor Rotation Direction Test: To ensure motors are wired for correct rotational direction.
