Overlay Graph of 5 Shock Tests (+ and - velocity), with Cursor to Pin Point Values



The Shock Dyno Retrofit Kit provides a load cell and length sensor, plus electronics to record both channels.  Once data is recorded, you can create reports or graphs of the results.  You can also overlay graphs from several different shocks for comparison.

Graph with just + Velocity


The program has several options, including:

You can graph results either absolute velocity (typical of most shock dyno programs) or versus velocity with direction.  This 2nd choice lets you pin point differences on the graph more easily with the cursor.

Modern USB electronics for easy installation on newer computers.

Overlay plots for comparison.

Temperature sensor (optional).

Start testing immediately or when a user selectable temperature is reached.

Summary of results as shown below, for max Compression  and Rebound force, Stroke, RPM, Test Cycles, Average/Max/Min temperature, etc.

Programmed or user selected test time.

Over-Force shutdown safety.  If the system detects a force greater than user selectable limit, the motor is turned off.  This can happen if you install the shock incorrectly.

The program is compatible with Windows XP, Vista, Windows 7 or Windows 8, which means it is easy to use and you will be able to print the results on most any printer, usually in color if your printer supports it.
