AC Voltage Measurement Steps Using Multimeter
1. Insert the black probe into the COM socket and the red probe into the V/Ω socket.
2. Place the function switch in the AC voltage range of V~range, and connect the test pen to the power supply or load to be tested.
3. When measuring AC voltage, there is no polarity display.
4. Whether measuring AC or DC voltage, personal safety should be taken into account and the metal part of the probe should not be touched casually.
For example, when measuring AC 220V, turn the switch to the desired voltage range (when measuring AC 220V, the switch should be turned to AC 750V). When measuring, the test pen should be connected in parallel to the circuit being tested. If you don't know the range of the measured voltage, you can first use a larger limit to measure the approximate value, and then switch to the corresponding limit measurement.
2, Operation prompt 1: Select the AC voltage gear. When the voltage range is unknown, start from the maximum range. 2. The table should be connected in parallel at both ends of the tested circuit or component.
3, The first step in measuring AC voltage is to turn on the power switch of the digital multimeter and rotate the multimeter to the AC voltage range of 750V. Step 2: Turn on the power switch in the circuit. Step 3: Measure the voltage between points 1-2, record the reading, and the voltage value is measured as 220V. Step 4: Rotate the multimeter to the AC voltage range of 20V, measure the voltage between points 3-4, 4-5, 6-7, and record the reading.
(1) The voltage measured between points 3-4 is 10V.
(2) The voltage measured between points 4-5 is 10V.
(3) The voltage measured between points 6-7 is 6.2V.
