Why is the speed reading erratic on my Stack Monitor?

If there is no speed reading or if the speed reading is erratic, with the value jumping high or low, it could be due to a faulty sensor and/or wiring (check sensor indicator for correct operation) or an incorrect sensor gap (too far or too close) - check that the gap is approximately 1mm / 40thou.
