Insert the red probe into the first, second, and third phase jacks when prompted by the flashing symbols on the display. 3. The "P --- L" symbol indicates a left rotation in the phase sequence, and the "P --- R" symbol indicates a right rotation. 4. If a timeout error occurs, indicated by the flashing "P," return to phase sequence testing and retest.

Q: How to use the NCV function? A: 1. Press the "F" button to select the "NCV" gear, and the "NCV" indicator will appear on the display. 2. Move the NCV sensor probe (located on the top of the device) close to the detection point. 3. If a strong AC electric field signal is detected, the screen will display "--H," flash red, and emit a rapid beeping sound. 4. If a weak AC signal is detected, the screen will display "--L," flash green, and emit a slow beeping sound.

Q: How to use the TSM-192? A: 1. Install the included batteries by removing the rubber sleeve on the back, opening the battery cover, and inserting 2 AAA batteries. 2. Turn on the multimeter in default auto mode and press the "F" button to select the measurement of Phase, NCV, and Live wire.
