Used Continuity Testers

Consider the tester's accuracy, durability, ease of use, and whether it provides both visual and audible signals. Check for additional features like auto shut-off or built-in lights.

Pack the tester in its original packaging or wrap it securely with bubble wrap. Use a sturdy box and add padding to prevent movement during transit. Label the package as 'fragile' if necessary.

Keep the tester clean and store it in a dry, dust-free environment. Regularly check the battery and replace it when necessary. Avoid exposing the tester to extreme temperatures or moisture.
