■ functional characteristics of automatic low voltage arrester comprehensive tester
▲ the instrument is controlled by microcomputer and has an all Chinese operation interface. It can automatically complete MOA test, absorption ratio and polarization index test of insulation resistance, and has functional options such as withstand voltage test and rapid test.
▲ high output power, short-circuit current greater than 5mA, that is, the charging current to the load is 5mA.
▲ electromagnetic compatibility design, strong impact resistance, safety plastic shell and easy to carry. Built in 3000mAh lithium battery with large capacity. Intelligent charging circuit, long battery life.
▲ it has the function of automatic discharge after the test, and there are sound and text information prompts during the discharge process. The discharge time to 60V is less than 10 seconds.
▲ the instrument will shut down automatically if there is no action for 10 minutes.
