A broad-range measuring device permits use of the test instrument in all alternating and 3-phase electrical systems with voltages from 65 to 690 V and frequencies of 15.4 to 420 Hz, as well as direct current systems with voltages from 65 to 800 V.

• Voltage measurement up to 1000 V AC/DC
• Low-resistance measurement for protective and equipotential bonding conductors with 200 mA, as well as automatic polarity reversal and 25 A
• Insulation measurement up to 1000 V with rising ramp
• Measurement of internal system resistance and fault loop resistance with high test current up to 690 V AC / 800 V DC without tripping RCD types A and B
• Testing of tripping current and time to trip for RCCB types A, AC, F, B, B+, EV, MI and G/R, as well as SRCDs and PRCDs
• Combined RCD test with continuously rising ramp, time to trip, tripping current
• Testing of RCMs and IMDs
• Measurement of leakage and differential current with the PROFICLIP current clamp
• Measurement of temperature and humidity with a sensor
• Mains and battery operation (with limited functionality)
• Creation of individualized test sequences
• Push-print function - transmission of the measured value via Bluetooth/USB after measurement has been completed
• Bluetooth and USB interfaces
• Windows-based user software with database functionality
