5.4 Calibration Procedure
To Calibrate the B-RAD Select:
1. See Section 3.4 – Unlock Levels to ensure the correct access level is enabled. Some settings in Calibration
are restricted to higher levels.
2. Install a fresh battery into the B-RAD Select.
3. Enter Calibration Mode by holding the button then pressing the button.
4. Select the correct Tool Model using Table 5.3 above. If the tool has previously been calibrated, this value
cannot be changed. Note that the units of the tool model are indicated by the green LED.
5. Navigate to the next Calibration menu labelled “SER.” The serial number is displayed.
6. The next two menu items show the lower and upper torque limits of the tool’s torque range.
7. Before any calibration points are set, it is recommended that the tool is warmed up near the tool’s maximum
setting. Navigate forward to “CPhi.”
8. Set the level to a value lower than 800 (the default is 750). Take a pull on the calibration stand.
9. If the output torque is lower than the rated maximum of the tool, gradually increase the tool percentage
until the torque readings nearly match the maximum torque of the tool. Adjust the value to achieve
approximately 50 units above maximum torque.
CAUTION!
DO NOT operate the B-RAD Select Tool System beyond 50 units above the rated maximum torque.
Overtorquing the tool will cause severe tool damage.
10. Do approximately 10 pulls around the maximum torque to warm up the tool.
11. Advance to the “CPLo” menu.
12. Take a pull at the default setting.
13. Gradually increase or decrease the percentage setting until the tool pulls approximately 50 units
below the
tool’s minimum torque. For example, a 1000 ft·lb tool has a minimum of 200 ft·lb, so the torque to be
reached would be 150 ft·lb. See Table 5.3 for a full list of B-RAD Tool ranges.
14. Navigate to the next menu in Calibration Mode. The display will show “CAL 1.”
15. Take one pull at “CAL 1” and record the measured torque value.
16. Enter the torque value (See Section 5.1 – Calibration Menu Navigation).
17. Navigate to the next Calibration menu “CAL 2.” Take a pull and record the measured value, as before.
18. Enter the torque value.
19. Repeat Steps 17-18 for the remaining CAL points.
20. Finally, exit Calibration Mode by pressing and holding both buttons until the display flashes and Torque
Mode is displayed. All Calibration data will be saved.
If the units are changed using the Information Menu (see Section 3.2.1 – Change the Torque Units), the
calibration values will be converted in the calibration menu.
6. TROUBLESHOOTING
Important!
Disassembling or attempting repair will void warranty.
If breakdown, malfunction, or error occurs, contact New World Technologies Inc. Technical Support (refer to
Section 7 – Contact Us).
The LED Display may exhibit abnormal behaviour depending on operating conditions, frequency of use, or
excessive wear on the Display Module.
The Display Module is designed to withstand normal use over the lifetime of the B-RAD Select Tool System;
however, as a sensitive electronic device it is susceptible to damage caused by shock, moisture, or excessive
force.
