6 Preparing for an Actiwave Cardio ECG Recording Electrode selection There is huge variety of electrode pads available to suit various applications. Signal quality is more dependent on skin preparation than pad type. Wear ability and adhesion are the main variables between pad types. recommend using your existing suppliers or searching the web to obtain the type of pads you require. -
Page 22: Electrode Positioning
Electrode Positioning The best ECG signals can usually be picked up by placing the round end of the Actiwave Cardio unit in a position midway between and below V1 and V2. The other electrode can be placed at V4 or V5. A position on the upper chest shown in the diagram below can also be used. -

Page 32: Faq & Troubleshooting
Why do the first few seconds sometimes show a DC offset To conserve power the Actiwave unit powers down during the start delay. When it powers up to start storing data the amplifiers need a few seconds to settle. - Page 33 ‘A device which may be an Actiwave has been detected’: The battery in the Actiwave is below the level required to communicate. This message is a safety warning to prevent users of other CamNtech products attempting to use the wrong interface.

Page 38: Appendix 2 - Installing Usb Drivers Manually
Appendix 2 – Installing USB Drivers Manually Sometimes the automatic installation of drivers will not work, often because your computer has previously had similar, but different, drivers installed on it before and sometimes because of flaws in the Windows installation process. - Page 39 Select ‘Install from a list or specific location (Advanced)’ and click ‘Next’. Select ‘Don’t search. I will choose the driver to install.’ and click ‘Next’. The window on the next page should appear. Sometimes, windows will decide to display some other windows first, possibly appearing to lock up for a minute or two at one point.
- Page 40 Ignore the items in the list, and click ‘Have Disk…’ instead. Click on ‘Browse…’ and then use the standard file window to find the ‘USB drivers’ folder on the CD. Select ‘ftdibus.inf’ from this folder and click on ‘Open’. The window above will re-appear with a filename at the bottom.
- Page 41 If this window appears, click ‘Continue Anyway’. The underlying drivers are in fact tested and approved by Microsoft, but the certification is invalidated when they are configured to match our reader devices. When this window appears your drivers are installed. Actiwave User Guide - Issue 2.0.18 Page 41...
