Introduction
An adjustable hand strap and a collapsible stand, that attach to the back of the Diagnostic Tool
housing, are available as optional equipment.
The padded hand strap threads through mounting slots on the Diagnostic Tool housing. Velcro
fasteners hold the strap in place and allow for quick adjustments. The strap keeps the Diagnostic
Tool snug to the palm of your hand while working.
The stand extends from the back of the unit to allow hands-free viewing. The stand clips into the
unit for storage and pivots out so that the display is at an angle when in use.
Contact your sales representative for availability of these and other options for personalizing your
Diagnostic Tool.

Your Diagnostic Tool can receive power from any of the following sources:
•

Batteries

•

AC/DC Power Supply

•

Vehicle Power

2.4.1 Batteries
The Diagnostic Tool can be powered from the internal batteries. New standard batteries or fully
charged rechargable batteries provide sufficient power for about 2 hours of continuous operation.
IMPORTANT:
The internal batteries are not intended to power the Diagnostic Tool during vehicle testing. Make
sure vehicle power is available to the Diagnostic Tool when performing vehicle tests.
2.4.2 AC/DC Power Supply
The Diagnostic Tool can be powered from a standard AC outlet using the AC/DC power supply.
The connector on the end of the output cable of the AC/DC power supply attaches to the data
cable connector on top of the Diagnostic Tool. Use only the AC/DC power supply provided.
2.4.3 Vehicle Power
All OBD-II/EOBD vehicles have vehicle battery power (B+) available on the DLC. The Diagnostic
Tool is powered through the Data Cable when connected to the vehicle DLC. A green LED
indicator on the DLC end of the data cable, illuminates when power is being supplied to the cable.
If the LED fails to illuminate, check that the data cable is properly connected and then check the
DLC power circuit. See
An optional power cable may be required when testing non-OBD-II/EOBD models that do not have
vehicle battery power (B+) available on the DLC. Contact your sales representative for availability.
