To measure AC voltage with the Klein Tools MM400 Digital Multimeter, follow these steps:
1. Insert the red test lead into the V jack and the black test lead into the COM jack.
2. Rotate the function selector switch to the V~ (AC voltage) setting.
3. Apply the test leads to the circuit or component you want to measure.
4. The meter will automatically range and display the AC voltage measurement in the most appropriate range.
Note: If the "-" symbol appears on the LCD, it indicates that the test leads are connected in reverse polarity. Swap the position of the leads to correct this.
Please refer to the "AC/DC VOLTAGE (LESS THAN 600V)" section of the instruction manual for more detailed information and safety precautions.
