2. INTRODUCTION
The LCCU21 series is a compact and light compression digital load cell
for force measurement. These can be used for the load distribution
measurement, compression measurement and etc. Also, connecting
the load cell to a computer using the USB cable allows for easy
measurement.
3. SOFTWARE FOR MEASUREMENT
By using the “WinCT-DLC” software for measurement, the measurement data can
easily be confirmed on a computer.
“WinCT-DLC” can be downloaded from A&D’s website (https://www.aandd.jp).

5. INSTALLATION
5.1. ATTACHING THE LOAD CELL
Attach the load cell to a rigid and flat base (the fixed surface). If there
is slope or distortion on a part of the base, it affects the measurement
accuracy.
The mounting surface is gray area on the bottom of the load cell in the
figure.
Do not apply load to the concavity of the center of the bottom ( mesh
area).
Don't defile with adhesive on mesh area.
Clean the mounting surface before attaching the load cell.
Fix the position of the load cell using adhesive or the mounting holder.
Adhesive used
Use the cyanoacrylate adhesive.
Push gently the load cell so as to keep the position. Paste the
adhesive to the place contacting the fixed surface and outer
circumference of the load cell. Hold the load cell until maintaining
the position. Do not apply excessive load and don't defile with
adhesive on mesh area.
Peel and shave adhesive using cutter and etc. when removing the
load cell. Don't hit and shock to the load cell when removing it. Note
injury and damage of the load cell in removing it.
Example of the load cell installation
Adhesive used
Mounting holder used
Put the load cell into the mounting holder. Fix them.
Note M3 bolts are not included in accessories.
Example of the load cell installation
Mounting holder used
When using the load cell by securing the plastic case, secure it as
shown in the figure below using the two installation holes.
Note M3 bolts are not included in accessories.
Use the load cell with the load cell and computer at the same potential.
Charging with the load cell may cause malfunctions.
Specifically, take measures such as grounding the load cell.
Grounding example
5.2. LOADING TO THE LOAD CELL
Load a vertical load to the load cell indicated in the figure below. Avoid
eccentric load, horizontal force and moment.
Directionofforce
Apply load to the load cell through a rigid surface.
5.3. CAUTIONS
Avoid a shock and excessive force to the load cell.
Keep a constant temperature using insulation, when the load cell is
installed in a place exposed to direct sunlight or radiant heat.
Handle the load cell cable gently. Do not pull it when using the load cell.
Prevent the plastic case from getting wet.
Only the provided USB cable should be used with this load cell. Using a
USB cable other than the provided USB cable may prevent the load cell
from making proper measurement due to the effect of noise.
6. COMPUTER CONNECTION PROCEDURE
1) Connect the device to the computer using the provided USB cable.
2) Select the device manager on the computer.
3) Click the "Ports (COM & LPT)".
4) Confirm the COM Port number displayed. The numerical value indicated
by x in "USB Serial Port (COM x)" indicates the COM Port number.
If multiple load cells are simultaneously connected to the computer
without confirming the COM Port number, COM Port identification
becomes difficult. Confirm the COM Port number one by one beforehand
when connecting.
* 4
5) Select the "Port Settings" tab in the "USB Serial Port (COM x) Properties",
then select "Advanced".
6) In the "BM options", set the "Latency Timer (msec)" under 10 (reccomended
value is 3). If it is not to set, a communication delay may result.
* 4 If the COM Port number cannot be displayed due to failure in installing
the driver, refer to the website of Future Technology Devices
International. Ltd. to install the driver.
