Chapter 1 Introduction
This chapter provides an introduction to the FSU products, describing the product range and main features.
Overview
The FSU product family comprises of Digital Sensor Cards that connect strain bridge sensors to your PC via USB. The FSU product is a compact, high-precision Strain Gauge Converter; converting a strain gauge sensor input to a digital output and is connected to a PC via a USB port. They allow high precision measurements to be made and communicated directly to a PC and is aimed at applications which require high-speed measurement.
Simply by plugging the device into a PC, data can be extracted from most strain gauge bridge input sensors and acquired by software which allows data manipulation removing the need for amplifiers, filters & multimeters.
Free-standing module fitted with 9-way ‘D’ type socket for load cell. Micro USB socket accepts a USB lead with type ’A’ connector at the PC end.
LED Status Indication
The module indicates status via a red Healthy LED.
When the FSU is placed in configuration mode the LED will be on solidly.
When the FSU is in recording mode and transmitting data the LED should flash ON for 100ms every 500ms (LED will be OFF but flash on for a tenth of a second every half a second). If the integrity of the load cell is in doubt the LED will flash OFF for 100ms every 500ms (LED will be ON but flash off for a tenth of a second every half a second).

Chapter 2 Getting Started
Install software (But do not run it) Plug FSU module into USB port Run software
This chapter explains how to connect to a FSU for the first time and how to get it working.
Communications Interface Information
FSU modules can connect to a PC by plugging into a USB port and do not require an external power supply as they appear as a ‘single unit load’ i.e. they draw <100mA. Appropriate USB drivers must be installed which are automatically installed with the FSU Toolkit software.
FSU Toolkit
The FSU Toolkit is a configuration and analytical tool designed specifically for configuring FSU modules. This toolkit allows configuration, calibration, data recording and review and for parameter management of the modules.
What Can The Toolkit Do?
Communications with a single module at a time to do the following:
Viewing of input with indication of integrity errors. Two point auto calibration by application of known weight. Two point table calibration from load cell calibration certificate. Setting System Zero. Engineering unit selection. Save module settings including user calibration and ability to restore to same or different USB FSU modules. Capture up to 30 minutes of data at 4800 Hz. Save data to CSV file. Navigate up to 30 minutes of data
captured from the FSU or loaded from a previously saved CSV file.
Trend chart view of live input. Exportable image and data. FFT view to identify frequency components of input signal. Simple oscilloscope view for wave based signals between 1 Hz and 500 Hz. Easily switch to alternative engineering units (If module has been previously calibrated)
It should be noted that traditional logging (Where the user start and stops a log) is not required with the FSU Toolkit. The FSU module operates in two modes. The first mode is where the measured value is being constantly transmitted at 4800 Hz and the other mode is configuration mode where the Toolkit can talk to the module but the measured value is not being constantly streamed. As will be seen later, the Toolkit allows capturing up to the last 30 minutes of data as long as the user stays out of the configuration pages. This 30 minute block of data is easily and quickly navigated to isolate data of interest.
Installing FSU Toolkit
Install the FSU Toolkit software by inserting the CD or USB storage device. This should start the ‘AutoRun’ process, unless this is disabled on your computer. (If the install program does not start of its own accord, run FSU Toolkit Setup.exe from the installation media. Alternatively launch the installer executable file which may have been downloaded from a web site.
The installation software pre-installs the required USB drivers so that they can be automatically found when the hardware is plugged in later on.

After the software has been installed please connect the module to the PC and see the next
section before running the FSU Toolkit
5
Connecting the Module to the Computer
Connect to a USB port on the Windows PC using the cable provided with the module.
Using the Found New Hardware Wizard
Connecting the module will cause the following dialog windows to appear. NOTE: Different operating systems may present different dialog windows but the dialogs shown below should allow you make the correct choices regardless of operating system.
Note that the FSU shares the drivers with the DSC range of modules so the driver is described as
the USB DSC Bus.
The ‘Found New Hardware Wizard’ should now appear. Select ‘No, not at this time’ if you are asked whether
the drivers should be searched for online. Click ‘Next’.
Now the wizard will start searching for the drivers.
The wizard should then proceed with installing the software drivers.
6
Using the Software
You can now launch the FSU Toolkit software.
Only one FSU module at a time can be connected to a PC!
The FSU Toolkit automatically detects the connected FSU module.
If the FSU module is detected when you launch the FSU Toolkit it will be automatically selected and the Information page will be displayed. If the module is not detected you will see the Home page at which you can wait until the FSU module is connected. Pressing the Detect button will start the detection process.
The Review page is also available at this point. See later in the manual for using the Review page. This will allow you to review previously saved data.
Recording occurs continuously in the background while on any of the following pages:
Capture, Review, Scope, FFT
and will continue even while navigating between these pages.
However, switching to any of the other pages
Home, Information, Save & Restore, Lock, Calibration
will cause the recording to stop.
7
Home Page
Click the icon to access the Information page.
After clicking the ‘Detect’ button and a module is detected you will then see the Information page.
8
Information Page
Click the icon to access the Information page.
No data is recorded while on this page.
This simply shows a large display and indicates if any error conditions are present by displaying an information box. The module serial number, firmware version and last calibration date are also shown.
If the module has been allocated engineering units these will be displayed in the lower right of the LCD display.
Units
If the calibrated units have been defined for this module then you can select from a list of alternative engineering units to use.
