MW 9320 - meter ground loop and RCD tester

Measurement without tripping earth loop
RCDs
• Measurement of line impedance
• Comprehensive test of circuit breakers
(Current, time, Uc ,...)
• Measurement of voltage, frequency and phase rotation
• New concept of compact and robust housing
• Graphic LCD
• indicator "PASS" "FAIL"
• Powered by rechargeable batteries (autonomy 20H)
• Support for integrated magnetic work "hands free"
• Safety: 600V CAT III and 300V CAT IV
