This is an indication of a short in the cable and it needs to be replaced. If you shake the hammer cable and it triggers, it is that cable. If it is the accelerometer cable that triggers, then replace that cable. You can run a test to be sure:
This is an indication of a short in the cable and it needs to be replaced. If you shake the hammer cable and it triggers, it is that cable. If it is the accelerometer cable that triggers, then replace that cable. You can run a test to be sure:
To test the hardware (hammer, accelerometer or DAQ Unit):
Connect all cables, hammer and accelerometer.
Open MillMax Software,
Click on "Hardware Test". The test will start.
Open MillMax Software,
Hold down CTRL button and press A. DO NOT tap as with the above cable test.
Click on "Hardware Test". The test will start.
If all three tests are completed and both the red and blue lines are solid and flat, the hardware is functioning properly.
If the red line shows noise, check the accelerometer cable and connections (specifically the threaded connection between the accelerometer and cable or the BNC connector and cable if not solid), then click on "Restart Testing" button. If its is the blue line that shows noise, check the hammer and cable, the retest. If the noise continues, the cable, hammer or accelerometer must be serviced.
