This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the device is used in its
installation. This equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the product manual, may cause harmful
interference to radio communications. If this equipment causes harmful interference, the
user is required to correct the interference.
Because of the phenomena being observed and the material properties being measured,
this equipment emits radioelectric energy when in active test mode. It must be ensured
that this radio energy does not cause any damage to people or equipment located
nearby.
Never exceed the maximum operational capabilities of the Baker DX tester, power
supplies, or Baker ZTX accessory. If the equipment is used in a manner not specified by
Megger, the protection provided by the equipment may be impaired.
Be sure to follow all safety procedures prescribed by your company, industry, and
applicable standards. Failure to observe these safety precautions may result in death or
serious electric shock.
Reference for additional information
The Baker DX quick reference guide is designed to provide users with an overview of the analyzer
and its basic testing and operating procedures. For complete safety information and detailed device
information, user license agreement, CE compliance, and more information on additional features,
refer to the Baker DX User Manual.

User interface main elements
NOTE
This section provides an introduction to the Baker DX software user interface
elements. For further details about the various modes. Mode submenus,
popup menus and other elements that can appear during testing, refer to
the Baker DX User Manual.
Figure 3. User interface main elements.
Main Display Area—displays all measurements, test results, and more as you execute your tests.
Status Bar—displays information about the Active Folder and Active Record. The elements show
you where the information will be saved for the motor currently under test. The right third of the
Status Bar is dynamic, displaying additional information such as the date and time, a running clock,
notice of active ZS Override mode, PTT Locked indicator, or a test counter when needed.
Mode Submenu—items here change depending on the mode selected along with other items
selected via the Mode Submenu itself or popup menus that appear in the Display Area.
Mode Menu—used to select the main mode of operation. Test and function modes are described
below. The Mode Menu does not change, and is always available.

Test and function modes
The large icons in the Mode Menu at the bottom of the touch screen represent the primary test
modes. When a Mode Menu icon is touched, the icon will be surrounded by a blue background
that indicates which mode the unit is in. The blue background also connects the selected mode
with its submenu above.
The graphic below identifies the test and function modes that become active when you touch the
corresponding icons.
Figure 4. Mode menu icon descriptions.
Mode submenus
The control icons for each mode appear in the submenu just above the Mode Menu. The Mode
Submenu icons correspond to the Mode Menu item selected. In the following example, we see
the descriptions of the Mode Submenu icons that appear when the RLC Tests icon is touched.
Figure 5. Mode submenu icons example.

Popup menus
Popup menus appear when specific functions are selected during the testing process. In the ex-
ample below, a popup appears in the Main Display Area when the RLC test selection icon is
touched.
The details of this popup menu are provided in the example below.
Figure 7. Popup menu icon descriptions for test type selection.

Preparing For Testing
Figure 8. Top bar showing voltage and megohms active.
www.megger.com 5
During HiPot testing, the top bar is active and can display two of the three measurement types
shown—either voltage and current, or voltage and megohms as shown in this example. The
grayed-out type is inactive.
To select which measurement type to activate, simply touch either the megohms or current displays.
Depending on what is selected (megohms or current), the scale on the right side changes. The plot
line in the Main Display Area also changes (black for megohms and red for current).
NOTE
While touching the values for current or megohm will change the
measurements and scales presented, touching the screen in other parts
of the Main Display Area will cause the unit to stop testing, which will be
recorded as a user abort.
The voltage scale is always displayed and its plot color is blue.
In surge mode, the elements change based on the type of coil selected for testing. In each mode,
a pulse counter shows you the number of pulses applied at a specific voltage during the test. If the
voltage changes (such as during ramp up) the counter starts over.
The pulse count also appears in the test report.
