ow does a Digital multimeter measure a battery?
Regarding the method of measuring the battery with the multimeter, the battery is not marked with the number of amps. You cannot use the multimeter and other instruments to measure the battery's amp. You can use the DC range of the multimeter to measure the voltage. When measuring the resistance of a certain circuit, cut off the power of the circuit under test. No live measurement is possible.
How to measure battery with multimeter
The battery is not marked with the number of amps. You cannot use a multimeter and other instruments to measure the battery's amps. Only the voltage (bit) of the battery can be measured, and the voltage can be measured with the DC gear of the multimeter.
Before use, you should be familiar with the functions of the multimeter. According to the object to be measured, the multimeter should correctly select the gear, range and test lead jack.
When the size of the measured data is unknown, the range switch should be set to the maximum value, and then switched from the large range to the small range, so that the pointer of the meter indicates more than 1/2 of the full scale.
When measuring resistance, after selecting the appropriate magnification gear, touch the two test pens to make the pointer point at the zero position. If the pointer deviates from the zero position, adjust the "zero" knob to make the pointer return to zero to ensure accurate measurement results. If it cannot be adjusted to zero or the digital display emits a low voltage alarm, it should be checked in time.
When measuring the resistance of a circuit, the power supply of the circuit under test must be cut off, and no live measurement is allowed.
When using the multimeter to measure, pay attention to the safety of the person and the instrument and equipment. Do not touch the metal part of the test pen with your hands during the test, and it is not allowed to switch the gear switch with electricity to ensure accurate measurement and avoid accidents such as electric shock and burning of the instrument.
