Multifunctional portable test instrument MI 3321 MultiservicerXA is intended to perform all necessary measurements for testing the electrical safety of portable electrical equipment, machines and switchgears.


Measuring Functions

  • Continuity tests (200 mA, 10 A);
  • Insulation resistance;
  • Withstanding voltage tests (1000 V, 1890 V, 2500 V);
  • Substitute leakage current;
  • Differential leakage current;
  • Touch leakage current;
  • IEC cord polarity test;
  • Leakage and load TRMS current measurement with current clamp.Portable RCD testing;
  • RCD testing.Line and loop impedance;
  • High resolution line / loop impedance (mΩ);
  • Discharge time;
  • Three phase voltage / rotary field;
  • Functional test.


Other features

  • 3 in 1: instrument perfoms testing of portable appliances (acc. to VDE 0701 0702), machines (acc. to IEC/EN 60204 Ed.5) and switchgears (acc. to IEC/ EN 60439 and the new IEC 61439) including functional and leakage tests for DUTs with nominal power up to 3.5 kW;
  • Multi-tasking: up to 18 different measurements can be performed either as a single test or pre-programmed test sequences (PAT mode);
  • Automated: automatic testing and PASS / FAIL evaluation of test results according to appropriate standard;
  • Project uploading: previous test data can be uploaded for fast retesting of the object;
  • Scan and test: optional barcoding sys-tem and PASS / FAIL barcode label printing make retesting quick and simple;
  • RFID: support for advanced RFID identification system;
  • User friendly: large LCD screen, full QWERTY keyboard, help screens and warnings make the instrument an extremely easy to use;
  • Fixed appliance tests: ports, leads and optional accessories fully support the testing of fixed machines and appliances while normal socket supports plugin machines and appliances testing;
  • RCD testing: instrument enables testing of parameters of RCDs and portable RCDs;
  • Clamp leakage current measurement: quick measurement of leakage current with current clamps directly on power supply cable without disconnection of appliance from mains;
  • Discharge time test: testing of how long it takes for the machine discharge after power is removed;
  • Withstanding voltage test: instrument perfoms 2500 VAC, 1890 VAC and 1000 VAC withstanding voltage tests with settable current limit;
  • Trend functionality: test results can be uploaded from PC to the instrument for comparison between old and new test results on site;
  • Downloadable: up to 6000 test results with measuring parameters can be stored in two level memory and downloaded to the PC with the help of PC SW PAT Link;
  • PC SW PAT Link PRO included in the standard set enables downloading, viewing, printing of test results and exporting of data to spreadsheet applications;
  • PC SW PAT Link PRO Plus enables advanced analysis of test results, data upload to the instrument for on site comparison of old and new results and creation of professional test reports.
