Before the replacement, the test leads must leave the measuring point and ensure there is no any signal at the input terminal. 5. Don’t use other unconfirmed or disapproved battery to replace the battery inside the meter. Only the battery of the same model or same electrical specification can be replaced. Before the replacement, the test leads must leave the measuring point and ensure there is no any signal at the input terminal.
