Troubleshooting
The SPC4™ System is designed to be accurate, reliable, and easy to use. If a problem occurs
during operation, follow the steps listed below to determine the source of the problem.
[1]
Re-read the operating instructions. Pay attention to
“NOTES”
and
“CAUTIONS”
[2]
Check battery functionality
1.
Open the battery compartment to visually inspect the battery connections.
2.
Remember to close the battery compartment afterwards.
[3]
Check the cleanliness of the probe sensor and SPC4™ fastener datum disc.
1.
Inspect probe sensor and SPC4™ fastener datum disc for debris or dirt. Most of the erroneous
load measurements are the result of a dirty probe and/or dirty datum disc.
2.
Check both surfaces periodically for metal chips, liquids, dirt, and accumulated oxidation on
the contact surfaces. Foreign matter accumulating between these surfaces will radically affect
the load measurements.
