7. Maintenance ● Battery replacement a. Disconnect the AC/DC Voltage Detector from the circuit under testing. b. Remove the battery cover, then take the batteries away and replace with new batteries (type AAA 1.5V x 2). c. Reinstall the battery cover. Battery Cover Batteries (AAA 1.5V x 2) - Page 11 ● Cleaning and storage : WARNING To avoid electrical shock or damage to the meter, do not get water inside the case. Periodically wipe the case with a damp cloth and detergent : do not use abrasives or solvents. If the meter is not to be used for periods of longer than 60 days, remove the batteries and store them separately.
