Uploading Data
To upload data, connect the serial cable from the computer to the tool and use the software to perform the
upload function. If communication errors are encountered, check the security of the cable connections and
the computer communication settings.
Communication Default Settings
The default settings for serial communications are: 9600 Baud, 1 Start Bit, 8 Data Bits, 1 Stop Bit.
Calibration
The calibration process for the 3000-Series

tools has three sub-processes. The fi rst is testing
the tool to fi nd the “as found” condition. If the tool is out of calibration, then two subsequent processes are
performed; calibration adjustment to bring the tool into calibration, and subsequent repetition of tool testing
to assure that the adjustments were effective and the results are valid. This process addresses only the
adjustment, not pre- and post-adjustment testing.
We strongly recommend that when performing the calibration process a torque tester of not less than
0.25% Indicated Value Accuracy be used, and that it be used in conjunction with a mechanical loader to
obtain proper loading of the tool. We have designed these tools to be as hand-position insensitive as we
can within other constraints, but the use of a mechanical loader is still recommended. The load applied
during testing must be at the loading point on the grip indicated by the plain ring at the middle of the grip.
It is imperative that when calibrating and testing one of the tools having the S/R dovetail that the calibration
be performed with an interchangeable head having the same Common Centerline Length as the head the
tool will be used with. Changing the Common Centerline Length does change the readings and using the
incorrect head will result in torque inaccuracy.
We strongly recommend that the tool be temperature stabilized before testing, and that fresh batteries
be used during the procedure to assure that the tool does not suffer a loss of battery power during the
process.
This section of this document presents the information required to make adjustments when the tool is found
to be out of tolerance.
Needed items (in addition to tester and loader):
•
A computer with a serial port and Hyperterminal software
•
The serial cable supplied with the torque wrench
Setup for Adjustment
1. Ensure the computer is operating and that tool power is disabled (off).
2. Connect the serial cable to the serial port on the computer.
3. Connect the single-pin connector on the cable to the serial port on the tool.
4. Start the Hyperterminal software on the computer. Note: Most versions of Microsoft Windows include
Hyperterminal sofware. Other terminal emulation software programs will also work for this procedure.
