"The PROFITEST INTRO provides professional electricians with a universal, compact and rugged, state-of-the-art measuring tool. The MT520T test instrument is capable of executing all measurements for testing the effectiveness of safety measures in electrical systems as required by IEC 60364-6 (DIN VDE 0100-600) and other countryspecific standards, and as specified in the individual sections of DIN EN 61557 (VDE 0413).Measurement of RLO, ZL-PE, ZL-N, RINS, RE, Î\"U, phase. sequence and voltage. OFFSET Management RL-PE \/ RN-PE \/ RL-N. Measuring functions can be selected directly via the rotary switch. Testing of RCD types A, AC, F, B, B+, EV, MI and G\/R, as well as SRCDs and PRCDs. Display of approved fuse types for electrical systems. Phase sequence measurement (including highest line-to-line voltage). Measuring of contact voltage by Finger contact. Connection of an RFID reader or a barcode scanner. Individual measured value memory and memory structure setup. Help functions with wiring diagrams. Bidirectional data exchange via USB, DDS-CAD and epINSTROM. Measuring category: CAT III 600 V \/ CAT IV 300 V. International prompting (12 languages).
