6.Communication Settings
Sets settings used for communication with the TMHSA.
The driver may not be recognized or the COM port number may change if the USB connection location
is changed. If a communication error occurs, the COM port number has probably changed. Check the
COM port and confirm that it matches the port number in the communication settings.
6-1. Checking the COM Port
Check the COM port for the TMHSA connection.
(1) Right-click the desktop Start menu, and select [Device Manager] in the displayed menu.
* In case of Windows 7, click the desktop Start menu and right-click [Computer] and select
[Management]. Click [Device Manager] in the [Management] menu.

(2) Open [Ports (COM and LPT)] in in Device Manager and check the COM port number.
Example: [COM4] is used in the following case.
.
6-2. Setting the COM Port
(1) On the menu screen, click [Communication settings].
(2) Select the COM port for the TMHSA connection and click [Save].

11
(3) Click [Check] to confirm normal communication.
Communication is normal if [@200] appears in the RXD box.
The following message box is displayed if communication was not successful.
See the previous instructions and recheck the communication setting details.

7.Calibration
7-1. What Is Calibration?
Calibration refers to the process of adjusting voltage output to match the torque acting on the torque
transducer to ensure that the electrical signal from the torque transducer can be output as an accurate
torque value.
For example, this adjustment ensures a voltage output of 10.000 V when a torque of 1,000 N·m acts on
the torque transducer.
7-2. Calibration Procedure
Switch to calibration mode.
Set the torque transducer to the initial torque state and
perform zero calibration.
With span torque applied to the torque transducer,
register the plus span point.
With minus torque applied to the torque transducer,
register the minus span point.
Connect the torque transducer to the PC.
Turn on and wait for approximately 10 minutes for the
torque transducer and PC to stabilize.
