When you're done, just remove the test leads. As for maintenance, regularly check the battery. You can easily replace the 9V battery in the field. Keep the tester in the padded carrying bag when not in use to protect it. Also, make sure to use it within the temperature range of - 20°F to + 140°F (- 29°C to + 60°C) to ensure accurate results. Avoid using it in wet or extremely dusty environments.
