Section 1

Before you can begin using your new DM-2A mark II gauge, there are a few quick tasks you’ll 

need to perform. You’ll find that setting up your gauge for first use and exploring its basic 
operations is a relatively simple operation that takes just a few moments. In this section, you’ll 
learn to install the batteries, determine battery health, and/or attach the power adapter. 

The DM-2A mark II requires four (4) rechargeable 1.5 volt NiMH (nickel metal hydride) AA type 

batteries to operate. To install the rechargeable batteries, follow these steps:

1.  Remove the panel labeled Battery Compartment on the under side of the gauge by 

loosening the screw using a Phillips screw driver (as shown next) and removing the 
battery compartment panel. 

  Do not open the panel labeled ‘No User Serviceable Parts Inside. Do Not Open.’ Doing so
