In the standard version 1.2, only Left and Right buttons are “software” buttons, Then the program can implement several functions (menus, etc) depending on the context, while up, center and down are “hardware/firmware”: the DAQ will perform a fixed function even if the computer is not runing, but that prevents to add more functions depending …
In most Braked dynamometers, the brake is installed over bearings and only the load cell prevents it to turn. Then the brake torque is converted to a linear force in the load cell as a result of the TQ / Lever (meters) formula. Note that torque can run in both directions, but normally we would …
Road Simulation is an ADVANCED mode, which is more intended for WLTP cycle, than for testing. Indeed Road Simulation is a kind of modified RAMP which uses a mathematical model to simulate what the vehicle should do in the road according to the instant output the vehicle performs Users that want to use Road Simulation …
Windows can eventually detect a high data stream from the DAQ (and previously from the Weather Station) and decide that it is a MOUSE, it will install the Ballpoint Drivers and will block the access from other applications. The cursor in the screen can become crazy as it will interpret the data from the DAQ …
The Capacitive Clamp (Red) (CAP-1) is envisaged to be used mainly on spark cables (High Voltage from coil to the spark). It senses the High Voltage peaks and sends them to the DAQ. In general it is good for single cylinder engines, Drawbacks: it may get random pulses from other cylinders There is also a …

Well. this shouldn’t be our duty as those are 3rd party sensors, but as it is a common request, these are the general rules:
During the installation / setup process it is common that some settings are not correct which can lead to ‘absurd’ readings (very high or very low). It is important to do this check list: After the installation: It may exist differences specially in high power cars and specially on twin roller dynos High Power Cars …
The provided USB-RS232 adapter has a default latency which results too slow for realtime data displaying. It does not affect to the recording but makes the visualization very slow. There are two options: FTDI Port Manually setting the COM Latency to 1 ms (advanced)
Something that causes many misunderstandings to new users regarding the SP1 configuration is the confguration of number of teeth and prescaler due to the fact that the SP1 does not syncrhonize these settings with the PC (the SP1 will not send this information during the connection process and then the PC will not be able …

Sure!. The general rule for the Low-Pass-Filter (the one that is set in seconds) is that the filter size shouldn’t be bigger than the test duration / 10 (the acceleration part). As a general rule an inertial dynamometer shouldn’t produce acceleration tests of less than 5 seconds (at the suitable gear), then the minimum filter …
