The ADM5201 advanced handheld automotive multimeter combines all the features of a full-function multimeter and integrates the functions of an O2 Sensor tester, PFI & TBI Fuel Injection testers.

This digital multimeter provides a quick and accurate diagnosis of the complete O2 circuit. It is also capable of sending a Rich/Lean signal to the ECM, and displaying crossing per-second (CC) and O2 voltage simultaneously when the secondary display shows test results. The bright LED backlight allows visibility in even the darkest conditions, and the sturdy over-molded case protects the unit better than the standard rubber boots that other units come with. A battery access door allows users to replace the battery and fuse without breaking calibration seals! Conveniently closed case calibration allows adjustments to be made directly through the Optically-Isolated RS232 serial port. This professional-grade multimeter provides efficient troubleshooting solutions to the most difficult problems encountered in today’s sophisticated automotive electronic systems.
