The 348-5430 Multi-Tool Gp provides several diagnostic tools in one handheld unit.
The Multi-Tool Group consists of a CAT® Multi-Tool, a diagnostic interface module (DIM), various power adapters and cords, a carrying case, and this manual.
| Illustration 4 | g02174304 |
348-5430 Multi-Tool Gp | |
The Multi-Tool (1) is a handheld tool that contains a software operating system and diagnostic programs (applications). The diagnostic applications are accessed by using the menu-driven display of the Multi-Tool and the keys on the front of the tool.
The DIM (2) connects to the back of the Multi-Tool and is used to connect test tools (cables and sensors). The DIM is the interface between the test tools and the internal software applications of the Multi-Tool.
The power adapters and cords supply power to the tool by using either of the following.
4 AC power cords are included for international use.
When the Multi-Tool is turned on, the main screen is the Application Manager screen. The Application Manager Screen is a menu screen that lists the programs (applications) available in the Multi-Tool. This screen is used to select and start each application.
| Illustration 5 | g02174305 |
Application Manager Screen. | |
The applications include the following:
To access an application, the application must be activated using a software license card. Activated applications appear at the top of the menu and are black-colored. Unactivated applications appear at the bottom of the menu and are gray-colored. After an application is activated, the application is permanently accessible. For details, see Activate Applications in the SETUP section of this manual.

Note: The Multi-Tool group includes four international AC power cords. If the correct power cord is not available, use an AC to DCwall power converter approved for your region and the DC power cable assembly. Use only the 285-0904 Power Cable As to supply DC power to the Multi-Tool. This cable protects the tool from (harmful) voltages and voltage spikes
Note: Do not use any other type of power adapter with the 348-5430 Multi-Tool Gp . Using any other power adapter can damage the tool.
Connect the 285-0907 Diagnostic Interface Module Gp (DIM) to the back of the Multi-Tool.
Note: Turn OFF the tool before installing or removing the DIM. The Multi-Tool and / or the DIM can be damaged if power is ON during installation or removal.
IMPORTANT: The Multi-Tool and DIM are calibrated together and have corresponding serial numbers. Do not interchange Multi-Tool and DIM units unless the Multi-Tool and DIM units are sent to the factory for recalibration.

Before an application can be used, the application must be activated (unlocked) using a specific software license card. After an application is unlocked, the software license card is programmed to work with only the Multi-Tool for which the card was first used. For this reason, the serial number must be recorded on the software license card for future reference. After use, the software license card must be stored in a safe and secure place.
