1) Go to docs.rcbenchmark.com/en/dynamometer/
software/dynamometer-software-download.html
to install the app.
2) Launch the application from your computer.
3) Connect the device to a computer using the USB cable.
4) Press the "Connect" button in the app as seen below.
Follow the instructions provided in the app to calibrate your
device. Recalibrate the device if it has been disassembled, if
the wires have been moved, or every 2 months.
1) Go to the "Utilities" tab.
2) Calibrate the thrust.
3) Calibrate the torque
and the weight.

The servo power rail of the Series 1580 in not connected. It is USB
powered (max 100 mA) by a jumper on the Series 1585.

Dangling wires may cause errors in the thrust and torque
measurements. Secure all wires and the ESC using tie-wraps or
double-sided tape. Wires from the motor to the ESC may be
secured along the load cells. If the motor has stiff wires, it is
recommended to perform a torque calibration for high precision
measurements.
Secure the device to a table using c-clamps or bolts.

Speed measurement
In the "Setup"tab of the app,
indicate the number of poles for
the motor you are using. Press
the icon for help on pole
counting.

Support and warranty

For feedback of questions regarding the installation of the device,
please contact us at [email protected].
RCbenchmark products are fully tested and inspected before
shipping. This product is covered by a one year warranty on
manufacturing defects.
The warranty does not cover misuse, product modifications, and
reverse polarity connections. When testing at high voltage, do not
use an ESC with a break setting activated. The breaking over-
voltage could damage the power measurement circuit.

The mechanical load on the motor is controlled by changing the
throttle and by installing a propeller of different size or pitch. You
may also perform your tests at multiple voltages.
You can manually control the motor for your tests and record
your data manually or continuously. These options are available
in the "Manual Control" tab.
You can also use the supplied scripts in the "Automatic Control"
tab to test and record motor data automatically.
If you have special testing requirements, you can use our very
powerful scripting functionnality. You have access to the full
power of Javascript, can control the dynamometer, export data,
and much more through our API. Example applications include
motor certification for production or repeatable tests for
characterization and research.
