Section 2

If you’re preparing your DM-2A mark II gauge for first-time use, or need to make adjustments 

to the gauge’s current setup configuration, this section will help guide you through the process 
and briefly explain the available options. Follow the steps in this section to access the setup and 
mode options. You’ll learn how to select device and mode setup options to enable or disable 
testing devices, set the power-down feature, set unit measurement preferences for area and 
volume measurements, choose European or North American decimal conventions, significant 
figures, and reverse mode. 

In addition to Retrotec’s complete line of fan equipment, your DM-2A mark II supports fan 

equipment from virtually every other fan manufacturer on the market. Chances are you have 
only one or two different types of fan equipment. Rather than forcing you to tediously scroll 
through all of the supported fan devices, the Device Setup sub-menu of the Setup menu enables 
you to custom-configure your gauge to show only the specific fan devices that you use. The 
final configuration is permanently saved in your gauge and can be changed at any time. Once 
configured, the d

 keypad button will cycle through only the devices that are currently 

enabled.

To access the device setup options and enable or disable a device profile, follow these steps:

1.  Press the O

 button to turn on your gauge. Press O

 a second time to exit 

the introduction screen and view the main operational screen. 

2.  Press the S

 button to access the Setup menu. 

3.  Use the   (Up) and   (Down) keypad buttons to navigate to Device Setup in the list 

(as shown next).
