7.  Device ranges and/or configurations can also be custom-configured if needed. For 

example, if you don’t require the low flow ranges for a Retrotec 2000 fan, you can 
configure the gauge to disable the L4, L2, and L1 ranges. This will prevent those 
ranges from being displayed when you press the R

 keypad button. To 

configure specific ranges, press e

 while the device is selected in the list to view 

the available range options. Use the e

,   (Left), and/or   (Right) keypad buttons 

to cycle between Yes (enabled) or No (disabled) beside the device range in the list. 

8.  Once you have ensured that the device you want to use the gauge with is enabled 

(and others are disabled, if desired), pressing the e

 keypad button to return to the 

main Setup menu and again to return to the main operational screen.

Your DM-2 mark II supports the calculation and display of a variety of house-testing and 

building-science parameters. Some of these parameters will be useful for your specific testing 
needs; others may be of little or no use to you. Rather than forcing you to tediously scroll though 
all of the supported parameters, you can use Mode Setup to custom-configure your gauge to 
enable access to only the specific parameters that are important to you. Configurations are 
permanently saved in your gauge and can be changed at any time. Once configured, the Mode 
keypad button will cycle through only those modes that are enabled in the Mode Setup menu.

To access mode setup options and change settings, 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.  Using the   (Up) and/or   (Down) keypad buttons to navigate to Mode Setup in the 

available list (as shown next).
