Registering Your MDX-Series Tester
Before using your tester, we recommend that you register it online to activate
your warranty. Registration will also make it faster and easier for you to obtain
technical support and service.
To register, log on at www.midtronics.com/warranty.html and have your serial
number ready. The number is at the bottom of the label on the back of the
tester.
Display and Keypad
When you first connect the tester to a battery, it functions as a voltmeter until
you press the
ENTER
button.
IMPORTANT:
If you connect the tester to a voltage source greater than 30 Vdc,
you may damage the tester’s circuitry.
The menu-driven display will then guide you step by step through the test
process. Use the keypad buttons to scroll to and select options in the menu.
To turn off the tester when not connected to the battery, briefly press and hold
the
MENU
button.
