- Simple instrument for indicating and testing the phase sequence of phase conductors and the rotation direction of drives
- Indicates the presence of all phase conductors and their phase sequence
- Determines the rotation direction of electrical drives contactlessly or by checking the correct phase conductor connections at the terminals
- Display of phase conductors L1/L2/L3 and the phase sequence in clockwise or counterclockwise direction via multiple LEDs
- Automatic testing directly when the device is connected
- Magnetic housing to simplify connection
- Color-coded connections to prevent incorrect connections
