What precaution should be observed when the multimeter isn't being used?

When a multimeter isn't being used, it's important to turn it off to conserve battery life and prevent accidental measurements. Additionally, store the multimeter in a protective case to avoid physical damage and dust accumulation. Ensure that the probes are disconnected and stored properly to prevent short circuits or damage to the leads. Finally, keep it in a dry and safe location to avoid exposure to moisture or extreme temperatures.
