Q: Why does my system not trigger when the hammer impacts the part?
- Most Common Solution: Check the trigger level setting in NDT-RAM software. It is possible that you simply need to lower the trigger level in order to get a consistent trigger.
- Check that the cabling from the hammer to the analyzer is connected and shows no visible signs of damage.
- Make sure that the internal hammer cable is not damaged:
- Manually impact the hammer tip with a part to see if you get a trigger.
- Open the hammer and physically wiggle the cable at different points. If the system triggers at random while doing so, the cable needs to be replaced.
Q: My system triggers just fine, but I get a weird signal on the screen with no peaks. What is happening?
- Power the system off and back on again and see if the issue resolves.
- Electrical noise can sometimes cause interference in the analyzer signal. A restart will fix the issue.
- Check that the microphone is not damaged.
- Test known parts to evaluate the signal – does it look like what you would expect to see?
- The microphone may need to be replaced.
