Capacitor Testing App
Like any electrical component, capacitors are sensitive to voltage spikes and swings and require regular testing to ensure proper function and safety. Use the Capacitor Testing App to ensure your capacitor readings are within acceptable rating range. Follow the open and close test procedures, record multimeter readings, document capacitor positions after testing, and more. This app is 100% customizable to accommodate your specific testing requirements and will work in both on and offline environments.
