Digital Battery Voltage & AC Ripple Tester

The RDH Robotics Voltage & Ripple Tester is a compact diagnostic tool designed to measure battery voltage and detect AC ripple caused by faulty rectifier diodes. It is ideal for battery chargers, inverters, UPS systems, automotive alternators, and power supplies, helping technicians quickly identify diode failures that can damage batteries and electronics.

• Accurate Battery Voltage Measurement
  Displays real-time DC voltage with a clear 3-digit LED display.

• AC Ripple Detection
  Detects AC ripple passing into the battery due to faulty or weak rectifier diodes.

• Ripple Status Indication
  Automatically indicates:

  • PASS / OK – Healthy rectifier

  • LOW – Borderline ripple

  • BAD – Faulty diode / excessive ripple

• Ripple Value Display (0.XX V)
  Shows actual ripple voltage after status indication for easy diagnosis.

• One-Button Operation
  Simple TEST button to switch between voltage and ripple test modes.

• Compact & Easy to Install
  Small enclosure with pre-attached power leads for quick connection.
