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. It is the first machine tester covering all necessary tests according to new IEC/EN 60204 ed.5 including Loop impedance, RCD and HV tests. MultiServicerXA enables measurement of discharge time, power and current consumption and resistance to excessive voltages which are the main parameters in the safety testing of hard wired appliances and large machinery. With an easy to use user interface, large graphic LCD, QWERTY keyboard, help menus with connection diagrams and extra ports for testing fixed installations the MI 3321 is the best solution for safety testing. Measuring functions • Continuity tests (200 mA, 10 A); • Insulation resistance; • Withstanding voltage tests (1000 V, 1890 V, 2200 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. Key features • 3 in 1: instrument performs 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).
