Device Tester ST 72 5
Execution: automatic test run with good/bad result display for class I, II (III) devices and cable test. Voltage measurement on an external socket with grounding. Three-phase objects can be controlled using optional adapters. The limit values of VDE standards are set. Battery capacity for 2500 measurements. Delivery with transport bag with belt, control wire with clamp for measurements, power cord with IEC plug and batteries.
Application: for technical safety tests (DGUV regulation, 3 tests) of electrical equipment and work equipment according to VDE 0701-0702, DGUV, regulation 3, ÖVE/ÖNORM E 8701, NEN 3140. Designed for use in electrical installations, in industry, for repairs, service and in local administrations.
Battery and mains powered. Control of devices with voltage-dependent connecting elements/power supplies/relays, such as electronically controlled devices/tools, information and communication technology devices and devices that can only be completely checked under mains voltage. Protective conductor current/touch current determined by differential/direct measurement. Memory of measured values up to 999 measurements, reading via micro USB interface. An additional, integrated real-time clock for recording measured values with the measurement date, a micro USB cable, a network cable and reading software (CD).
Performance test: RPE, RISO, System continuity/short-circuit checking/neutral conductor; protective conductor current/touch current using the equivalent leakage current method: 0,25 mA – 20 mA; protective conductor current/touch current by differential/direct measurement: 0.25 mA–20 mA/0.1 mA–2 mA; protective conductor current of 3-phase objects to be inspected (function condition) (optional): 0.25 mA – 10 mA Performance test: RPE, RISO, System continuity/phase conductor/neutral circuit check; protective conductor current/touch current using the equivalent leakage current method: 0,25 mA – 20 mA; protective conductor current/touch current by differential/direct measurement: 0.25 mA–20 mA/0.1 mA–2 mA; protective conductor current of 3-phase objects to be inspected (function condition) (optional): 0.25 mA–10 mA
