1 Introduction
1.1 Concept
WhaleTeq DFS100 is designed for AED field tester. AED (Automated
External Defibrillator) is a life-saving medical device that delivers
defibrillation upon identifying and analyzing the ECG of a resuscitation-
needed patient. Because AEDs are installed in public areas where they
can be reached before ambulance arrival, the majority of AEDs rely on
one-time batteries and requires only minimal training compared to
hospital-use defibrillators. Ensuring the functionality of AEDs
periodically becomes widely accepted around the world, and DFS100 is
the ideal tool to conduct such a regular inspection.
1.2 Applications
WhaleTeq DFS100 is a compact field tester, functioning as an ECG signal
simulator and defibrillation energy guarantee equipment for AED
regular maintenance.
For ECG patterns simulation, DFS100 simulates NSR (Normal Sinus
Rhythm) as well as other arrhythmias that may need AED defibrillation.
Arrhythmia convert combination (ECG waveform before vs. after
defibrillation) is also available.
For energy guarantee, DFS100 allows User to customize the pass/fail
criteria of the delivered defibrillation energy. To ensure the durability
of DFS100, protection against multiple defibrillation is implemented.
(DFS100 should be used to analyze defibrillation energy at the interval
of at least 60 seconds)

4 Getting Started
4.1 PC System Requirements
DFS100 Setup Software uses a Windows PC to connect and modify
DFS100 via USB module.
PC requirements:
- Windows PC (Windows 7 or later, suggest to use the genuine
version)
- Microsoft .NET 4.0 or higher
- Administrator access (essential for installing software, driver, and
Microsoft .Net Framework)
- 1.5 GHz CPU or higher
- 1GB RAM or higher
1
- USB port
4.2 Software Installation
Please follow the steps below to download and execute DFS software.
1. Download DFS100 software from WhaleTeq’s website.
2. Open the file explorer and select the download location.
3. Double click on WhaleTeqDFS100.exe to execute DFS100 PC
software.
Note:
If DFS software cannot be executed properly, or this is the first time
using WhaleTeq’s product, please refer to the two sections below (4.3
and 4.4) to confirm that the USB driver and Microsoft .Net Framework
4.0 are both installed.

Relative to normal PC processing, there is no special use of PC speed. However, there has been
noted a slow increase in system RAM usage over long periods of time up to 30-40MB (related to MS
Windows “garbage collection”). PCs with only 512MB or less installed and are running several other
programs (in particular, Internet Explorer), may exceed the available RAM, requiring access to the
hard drive and dramatically impacting speed. In this case, streaming interruptions and other
problems may occur.

4.3 USB Driver Installation
If Windows Device Manager can’t recognize WhaleTeq’s product,
please follow the instructions below to install Microchip® USB Driver.
For Microsoft Windows 10
⚫As Windows 10 has built-in Microchip® USB Driver, there is no
need to install any drivers. It just takes a while for Windows
Device Manager to recognize and install the driver.
For Microsoft Windows 8 and Windows 8.1
⚫If Windows 8 and Windows 8.1 can’t recognize DFS100 unit,
please download “mchpcdc.inf” from WhaleTeq’s website. This
driver is provided by Microchip®, and is intended to be used with
PIC microprocessors which have built-in USB functions.
⚫As mchpcdc.inf provided by Microchip® does not contain a digital
signature, please disable the driver signature enforcement in
Windows 8 and Windows 8.1. Please click here to watch the
tutorial video.
⚫When the USB module is connected for the first time, select
Manual Installation, and point to the folder containing the above
file. Then, continue to follow the instructions to finish the
installation. There may be a warning that the driver is not
recognized by Windows®, and this can be ignored. Please click
here to watch the tutorial video.
For Microsoft Windows 7
⚫If Windows 7 can’t recognize DFS100 unit, please download
“mchpcdc.inf” from WhaleTeq’s website. This driver is provided
by Microchip®, and is intended to be used with PIC
microprocessors which have built-in USB functions.

16
⚫When the USB module is connected for the first time, select
Manual Installation, and point to the folder containing the above
file. Then, continue to follow the instructions to finish the
installation. There may be a warning that the driver is not
recognized by Windows®, and this can be ignored. Please click
here to watch the tutorial video.
4.4 Microsoft .Net Framework Installation
WhaleTeq’s software is developed based on Microsoft .Net
Framework 4.0. If DFS software fails to execute properly, please check
whether Microsoft .Net Framework 4.0 or a higher version was
installed in the operating system.
If the PC hasn’t installed Microsoft .Net Framework 4.0 or a higher
version, please download it from Microsoft’s website. Please click
here to watch the tutorial video (from 2:03).
4.5 PC Software and Firmware Auto-Update
User can download the latest software from WhaleTeq’s website. If
User cannot update the DFS software, please contact WhaleTeq’s
service team ([email protected]).

5 PC Software Operation
5.1 Software Function Introduction
Figure 5: PC Operation Interface
The DFS100 PC Software is solely for customized settings. It does not
include testing functions.
A. Default Pattern When On: User can choose from VT (Ventricular
Tachycardia), VF (Ventricular Fibrillation), or NSR (Normal Sinus
Rhythm) as the default playing pattern when turning on DFS100.
B. Return To Initial ECG Pattern: When using ONE-TIME TEST mode
, User has the option to enable the “Auto Return to Initial ECG
Pattern” function, which does so upon 30 seconds after receiving
defibrillation.
Note:
If User doesn’t enable the “Auto Return to Initial ECG Pattern”
function, User will need to manually switch the pattern from NSR
to VT or VF if needed for the next inspection.
C. Joule Threshold: Depending on different models of DUT (AED),
the delivered defibrillation is different. DFS100 allows User to self-
define the passing criteria of the defibrillation. If the joule of the
defibrillation equals to or is higher than this value, the AED
Discharge LED lights green; otherwise, lights red.
Note:
User can set the parameter from 40 to 360 Joules.
D. Auto Off: DFS100 will automatically be turned off after being idle
for a certain time. The default value is 3 minutes.

Note:
User can set the time from 3 to 10 minutes.
E. Check for Updates: Click to see if the latest version of firmware
and/or software has been released. Please note that the USB
cable used for firmware upgrade must be file-transferrable.
F. About: Check the software version and the device function
introductions.

6 Standalone Operation
6.1 One-Time Test (Convert)
In this mode, the test starts immediately upon DFS100 being turned
on, and it simulates the ECG pattern of a resuscitated-needed
patient.
Ensure the AED and DFS100 are connected properly via the interface
cable. Turn on both DFS100 and the AED, and follow the AED
instructions. The default setting of DFS100 is sending VT to the AED.
After the AED delivers defibrillation shock, DFS100 shows the pass/
fail of the defibrillation energy by lighting different LED colors for 30
seconds.
Note:
If the test passes, the LED lights green. If the test fails, the LED lights
red.
At the same time, DFS100 simulates the patient having been
resuscitated by changing the ECG pattern to NSR.
6.2 Continuous Arrhythmia Test
In this mode, DFS100 continuously sends user-selected arrhythmia
to the AED.
Ensure the AED and DFS100 are connected properly via the interface
cable. Turn on both DFS100 and the AED, and follow the AED
instructions. The default setting of DFS100 is sending VT to the AED.
After the AED delivers defibrillation shock, DFS100 shows the pass/
fail of the defibrillation energy by lighting different LED colors for 30
seconds.
Note:
If the test passes, the LED lights green. If the test fails, the LED lights
red.
Then, User may connect DFS100 to the other AED for the next test.
The test starts without User pressing any button on DFS100.
