1Introduction
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. The procedure
requires special components that may be purchased from NORAC.

4Setting Up
* Refer to Appendix A for setup and calibration of the 44730
calibration stand.
4.1 Assemble the two parts of the test stand as shown in Figure 2.
Insert the sheet metal insert into the rectangular hole. Install the
spring, flat washer and wing nut onto the stud. Tighten wing nut until
the spring is approximately half compressed.

4.2 Insert the alignment tool (44968-2) into the test stand. (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.
4.4 Using the adjustment screws (B and C), align the tip of the alignment
tool to the center of the golf ball
To move the tip of the rod upwards, turn both adjustment screws
in an equal amount.
To move the tip of the rod downwards, turn both adjustment
screws out an equal amount.
To move the tip of the rod side to side, turn one screw in and one
screw out an equal amount.
4.5 Rotate the alignment tool 180 degrees and repeat the alignment
process (Step 4.4). If after rotating the alignment tool the tip of the
rod is not centered on the ball target, split the difference of the two
calibrations.
4.6 It may be necessary to adjust the threaded mount of the ball target (A)
after Step 4.5.

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. The underlying
gold foil should be clean and free from tears, chemical deposits or
wrinkles. Ensure a clean foam disc is in the sensor before testing.
NOTE: It is advised that a new foam disc is used for sensor
testing.
4.9 Mount the sensor into the sensor test stand. Press the handle
towards the stand and insert the sensor with the transducer facing the
golf ball as shown in Figure 4.

4.10 Attach the USB end of the USB-to-Serial Adapter to the computer and
ensure that the Serial end is attached to the Bus Monitor.
4.11 Connect the Bus Monitor’s Power connector labeled “To CANBus”
to the Bus Monitor Stand-Alone Power Cable connector labeled “To
Bus Monitor”.
4.12 Connect the banana plugs on the Bus Monitor Stand-Alone Power
Cable to a 12Vdc power supply.
4.13 The red banana plug must be connected to the positive terminal and
the black banana plug to the ground.
4.14 Switch the power supply on, check that the LED on the Bus Monitor is

7
illuminated and switch off power supply.
4.15 Connect the sensor cable to the Bus Monitor Stand-Alone Power
Cable AMP connector labeled “To CANBus”.
4.16 Once the sensor is connected to the Bus Monitor, turn on the power
supply and allow the sensor to run for at least 5 minutes before
proceeding to Section 5.
