18 reproducible fault patterns in three circuits. The trainer doesn’t tell you what’s broken—it shows you the symptom. And Generation 4.0 completes the learning path: search, measure, repair, prove. Only when function is restored is the diagnosis confirmed.
What the trainer does in class — shown in a minute, with sound. Subtitles can be switched on in the player.
Each of the three program selector switches introduces a defined fault into its section of the circuit—and then removes it again. No need to rewire, replace components, or make preparations between two groups. The teacher sets a number, and the class measures. Two minutes later, the next error pattern appears.
Art. No. 12020240 It's not the stated fault. The 18 levels are designed so that the cause isn't determined until the end of the test series—and the trainee then corrects it on their own.
A diagnosis is only confirmed once functionality is restored. The self-resetting fuse allows the fault to be safely bypassed using a jumper wire—the student goes through the entire workshop workflow: search, measure, repair, prove. That’s the difference from the previous model.
The levels are divided into three stages: first, the lamp circuit with voltage drop and contact resistance; then, the relay with its control and working circuits; and finally, the MOSFET stage with gate drive and negative voltages. Each stage builds on the previous one.
The tasks require a reasoned guess before the first measurement. This reveals whether someone is searching systematically or guessing—top-down versus component-by-component—and why that makes a difference.
A switch instead of a tool. The trainer is ready for use again between two groups with no setup time, and the same fault can be reproduced exactly for the test—identically for every trainee.

The Multimeter Diagnosis 4.0 comes in once the circuits are solid and the focus shifts to finding faults. It builds on the fundamentals of the vehicle electrical system and progresses to signal diagnosis using an oscilloscope.
The tasks are not sorted but are arranged in stages: V1 performs voltage drop testing in the lamp circuit; V2 isolates the control and load circuits at the relay; V3 deals with the semiconductor drive. Includes a digital curriculum and accompanying E-Learning.
The TP-Lab Multimeter Diagnosis 4.0 comes with a complete course on TPGO. It runs in the browser — tablet, phone, computer. The tasks walk through the same measurements the apprentice takes on the trainer: first the assumption, then the series of readings, then the comparison.

For existing customers
Buy one trainer from Generation 4.0 and the e-learning courses for every predecessor model you already own are unlocked with it. At no extra cost. For the TP-Lab Multimeter Diagnosis (Art. No. 12 020 210) that means 18 tasks in 27 chapters, around 8 hours of hands-on work — on the same domain, with the same progress.
The course covers the same material as its predecessor—with one exception: troubleshooting. Trainees not only find the fault, but also fix it. That is the pedagogical leap.
Tell us your inventory and have it unlocked arrow_forwardA demonstration lasts about two hours. We'll set up a fault and let you troubleshoot it—using your own multimeter. Afterward, you'll know if the trainer is a good fit for your class.
