Introduction: Multimeter is one of the most basic skills in electronics. It is a good assistant to test and troubleshoot the faults existing in electronic equipment. This digital multimeter voltmeter ohmmeter ammeter will meet your needs. Made of durable materials, it is sturdy and durable for long-term use. In addition, it can also be used to measure the remaining capacity of rechargeable batteries to check whether the battery is fully charged (battery not included).
