Common Faults and Solutions for Asphalt Extensometers
The common faults and troubleshooting methods for the asphalt ductility tester are as follows:
① Fault: The leakage protection device trips upon power-on.
Cause: The leakage protection device detects ground current. Since this instrument requires grounding to operate, some units may cause the leakage protection device to trip.
Solution: Bypass the power supply through the leakage protection device, or replace it with a leakage protection device that allows for a higher leakage current.
