Introduction to the current gear of the digital multimeter
Connect the meter in series to the circuit to measure and monitor the current. If the current deviates far from the normal value (based on experience or the original normal parameters), the circuit can be adjusted or repaired if necessary. You can also measure the short-circuit current of the battery by using the 20A range of the meter, that is, connect the two test leads directly to both ends of the battery. Remember that the time should never exceed 1 second! Note: This method is only suitable for dry batteries, AA batteries, AA batteries, and AA batteries. Beginners should be guided by personnel who are familiar with maintenance, and must not be operated by themselves! The performance of the battery can be judged according to the short-circuit current. In the case of a fully charged battery of the same type, the larger the short-circuit current, the better.
