The Computer System
The computer system consists of a standard
computer with up to three monitors installed,
a color printer, and WinDyn dynamometer
software. Other than the network connection and
minimum performance specifications, no special
requirements must be met.
SuperFlow’s WinDyn dynamometer software
was designed for Microsoft
®
Windows
®
-based
computers.
The computer communicates with the sensor
system through an Ethernet Local Area Network
(LAN) cable. Commands to the test system can
only be issued from this computer.
All printers supported by Windows can be used.
A color printer is recommended for highest impact
and clarity of test graphs. The printer is connected
to the computer.
Electrical Requirements
The WinDyn instrumentation system requires a dedicated, stable electrical power source for proper
operation. SuperFlow recommends using an Uninterruptible Power Supply (UPS) that has a minimum
rating of 750 VA or a high-quality surge suppressor for the sensor box and computer. This may protect the
electronics from damage in the event of a power surge and keep the engine running if the power goes out.
It is best to connect all instrumentation devices to the same circuit to minimize ground loop noise. Adding
devices such as battery chargers and fan motors to the same circuit can cause noise problems.
The total power requirement for a basic instrumentation system is 120V/15A or 240V/8A.
TIP:
Your electrician can wire the electrical circuits in your test cell with outlets for the sensor box and
computer wired to a special protected circuit.

SuperFlow recommends dedicating the computer
connected to the dynamometer for dynamometer
use only and not utilizing it for other purposes.
Multiple programs and Internet access could
possibly slow down the computer and affect the
dynamometer operation.
