YF-80 Phase Rotation Tester
- Detect the phase sequence (R-S-T) of 3-phase circuit
- Electronic circuit configuration allows more specific function display
- Automated detection for low-battery capacity
Application
Phase rotation indication by both audio and indicator, checking if currents of three different rating are in proper phase. Phase open-circuit detection by indicator.
Features
- Electronic circuit configuration allows more specific function display.
- YF-80 can detect the phase sequence(R-S-T) of 3-phase AC circuit.
- Phase-rotation indication: by both audio and indicator.
- Phase open-circuit detection: by indicator.
- Automated detection for low-battery capacity: YF-80 will pick up automatically the insufficient battery power and displayed by the indicator. Insufficient battery power will lead to error in testing.
