PROGRAM CARDS AND CARTRIDGES
The Mastertech uses plug-in program cards and cartridges which contain the software programs for testing
specific vehicles and systems. The program cards and cartridges are upgraded periodically to include new
vehicles, model years, and systems. Specific operating instructions are provided for diagnostic test functions
contained in the program cards or cartridges.
Program cards, TECH 1 cartridges, and Input/Output (I/O) cartridges can be used with the Mastertech
Multi-Function Tester.
PROGRAM CARDS
Multiple program cards may be required to provide the complete diagnostic testing capabilities of the
toolset. Program cards are installed in the slot on the upper right side of the tester (below the display). The
program card slot is keyed so the card can only be installed in the proper orientation.
TECH 1 CARTRIDGES
Most cartridges designed for use with a TECH 1 or TECH 1A tester are fully compatible with the
Mastertech. TECH 1 cartridges plug into the cartridge slot and allow you to test most US vehicles as well as
many European and Asian manufactured vehicles.
I/O CARTRIDGES
Input/Output (I/O) cartridges are used to expand the I/O capability of the tester. I/O cartridges plug into the
cartridge slot at the top rear of the tester.
