    1. Coupling Assembly 2. Flexible Loop Open the coupling connector and circle around the conductors. Then re-connect the coupling connector. 3. 50/60 Hz button Press this button to select nominal frequency (50 or 60Hz). It is also used to decrement the order of harmonics or CT ratio. If this button is hold when turning on power, the tester can perform measurement of phase sequence instead of phase angle in the balanced 3Φ...
