Transducer Test
The Transducer Test menu houses functions which allow the transducers digital output
to be monitored, or its internal status viewed
Data Capture
The Data Capture function is a simple interval data capture, which records torque data
to a CSV file.
To capture data, use the “Capture Rate” slider bar to select a capture rate, i.e. how
many data points per second. Next, press the browse button and use the “Save As”
dialog box to select an output file. Press the “Start” button to initiate a capture. The
records captured count
will be shown in the “Record Count” box. To stop, press the
“Stop” button shown on screen. A stopped capture cannot be restarted, you must either
select a new file or overwrite the current one.
The following descriptions describe the different fields.
Mode
The
“Mode” text box describes the capture method used by the program and
transducer. The method depends on the connection method and firmware version. The
“USB Optimised” mode buffers data in the transducer, and transfers the data in bulk
packets, making use of the USB bandwidth available.
“Poll Mode”, polls the transducer
at the requested frequency.
Capture Rate Max (Hz)
The “Capture Rate Max (Hz)” text box, is the maximum capture rate available for the
combination of connection method and transducer firmware. This value is the actual
internal capture rate for
“USB Optimised”, or a theoretical value based on bandwidth
for “Poll Mode”.
