ZEROTESTpro
ZEROTESTpro - Loop/Line Tester
Features:
- Fault Loop and Line resistance and prospective fault current
- Fault Loop resistance and prospective fault current (no-trip of a RCD)
- The database (table) of fuses’ types/disconnecting times/rated currents in the memory of the ZEROTESTpro enables to evaluate automatically the measurements results
- AC TRMS voltage 24,0 ÷ 260,0 V
- Phase (live) conductor test
- The bright multicolour OLED display
- Patent-protected storage of the test tips in transport position – sharp tips are safely hidden
- The bright LED near the test tip allows you to illuminate the measured area
- The instrument is powered by four AAA rechargeable NiMH/NiCd batteries that can be charged inside the instrument
