Question
Answer/countermeasure
Setting/
operation
How to reduce digits of
numerical values?
Change the decimal place (torque) in calibration when setting the
sensor type, reduce the number of digits of rated capacity, and
perform equivalent input calibration or actual load calibration.
Low order digit of indicated
values fluctuates.
Is calibration of approx. 30000 or more performed at 5V?
Since resolution is approx. 30000 per 5V, if calibration is
performed more than 30000, scale division becomes rough, and
indicated value fluctuates and is not stable. Ignore the low order
digit if using the product as is, or reset the min. scale division.
USB
The PC application display is
abnormal.
Displaying stops.
"Setting error", "XXX
acquisition error",
"communication error" or
"communication time out error"
are sometimes displayed.
Is the USB cable wired in parallel with the AC line?
Re-wire the USB cable so that it is not in parallel with the AC line.
Does the ALM (red) lamp light on?
Is the correct COM port number selected for the PC application?
Is the USB cable properly connected to the PC?
Refer to the PC application help, open the Device Manager of the
PC and check the virtual COM port number and selected number
to which the TM201 is connected.
The virtual COM port number
does not appear in the Device
Manager of the PC even if the
TM201 is connected.
Is the USB driver properly installed?
Remove the USB cable of the TM201 once, and reinstall the USB
driver.
The USB driver cannot be
installed.
Right-click the driver software as a user with administrator
privileges or as an administrator, and select execute to install it.
Check the website and guide of FTDI Limited.
Caution
●
Use shielded cables (for USB and UTM).
The AC adapter accompanying as standard does not comply with CE marking
compliance.
In case the AC adapter which complies with CE marking compliance is required,
please specify when you order.
