| Features |
| The DU-3282 has a real-time open circuit monitoring function, which limits the instrument to only be tested when the circuit is normal. During the entire testing process, as long as there is a circuit disconnection, the test will be stopped immediately and an alarm will be triggered. The indicator light will indicate the faulty position, and the 100% accuracy test will be maintained. |
