  • Page 4: Introduction

    This manual serves as an instruction manual for testing UC4+, UC4 and UC3 sensors. This procedure is useful in determining if a sensor needs to be returned to NORAC for repairs or if it is possible to continue using it. This procedure also provides a method for performing some basic calibration of the UC4 sensor to improve its performance.

(Figure 3) 4.3 Adjust the threaded mount (A) of the golf ball target so the surface of the ball will touch the tip of the alignment tool (it may be necessary to align the calibration stand first (Step 4.4) before this is possible.
  • Page 9 4.7 If the test stand is ever disassembled, it must be realigned when reassembled. Use the alignment tool to check the alignment of the test stand before each use. 4.8 Inspect the sensor for visible damage. Inspect the transducer by removing the foam and looking through the screen.
