Yes. An automotive multimeter is a very precise and sensitive piece of electronic equipment and is easily damaged if handled or operated negligently: Never drop the device. Always ensure the correct range is selected on analogue and scalable digital meters. Make sure AC or DC settings are correctly selected before taking a reading. Ensure the correct polarity when carrying out DC readings. Additional operating tips can be found in the “Safety Tips When Operating An Automotive Multitester” section, above.
