
FanTestic installed
Start the software program, create a new test, and ensure the test standard is being used is ATTMA (see
section 1.6).
The Settings should be reviewed because this will dictate how the automatic test is to be performed, see
section 1.9. The default settings can be changed before any test.
6.2 Connect your Gauge to the Computer
DM-2 (use USB connection)
Connect your DM-2 to the computer with the supplied USB to mini USB cable.
Note: The mini USB on the DM-2 is the control connection for automatic testing and is connected to the
USB on the laptop or hub. The yellow Ethernet style connector is the Fan Speed Control Cable and is
NOT used to connect the gauge with a computer or network, it simply goes between the DM-2 and the
fan so the gauge can control the fan speed.
Note: If you have more gauges than the number of USB ports on your computer, you can purchase an
actively powered USB HUB from an electronics store, which allows multiple USB inputs.
Also, any DM-2 gauge that is older than Firmware Version 3.0 requires an Active Powered USB2.0 High
Speed HUB. In other words, DM-2 gauges with Firmware versions 3.0 and later may not require actively
powered USB HUBs – The firmware version is displayed when you turn on the DM-2 gauge, and on the
DM32 with WiFi connection
Turn your DM32 gauge on.
Check that the selected device matches the fan you are going to use for the test, and the correct range is
chosen on the gauge to match what is installed on your fan.
From the home screen, tap “Settings”, then tap the “…” key. Check that the setting key labeled
“Network” reads “WiFi Create” in white text. If not, tap it and then tap “Status” until it reads “WiFi
Create” then go back to the home screen. The DM32 gauge will create a WiFi hotspot that your
computer can connect to.
Connect your computer to the WiFi hotspot created by the DM32 gauge (when it is set with “Network” =
“WiFi Create”) using your normal Wireless connection panel - same procedure you would use to connect
to the wireless hotspot at the coffee shop.
Depending on your version of Windows, it will look something like:
