Don’t use other unconfirmed or disapproved battery to replace the battery inside the meter. Only the same model or same electrical specification battery can be replaced. Before the replacement, the test lead must be removed from the measuring point to ensure there is no longer any signal at the input terminal.
12. When “ ” is shown on LCD display, please replace battery immediately to ensure the measurement precision. 13. It is not allowed to insert the test lead into the current terminal to measure voltage! 14. Please don’t change the circuits of the meter freely for fear that the meter is damaged and the safety be endangered.
