DM-2A Mark II 2008-02-22
Section 1
Getting Started
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.
Installing the Batteries
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
will void your calibration and warranty.
