Bonjour, HighVoltage:
Many thanks for this note: "I had very bad experience with PMK 1000x Probes and killed a few of them without obvious reasons."
Can you detail your "very bad experience" that killed them?
As designer, and manufacturer of SMPS, HVPS, since 1970s, we used the classic Tektronix P6015, P6015A for decades, never any issues.
We discovered the PMK X1000 probes recently thought to try a pair, as the PMK probe bodies and comp boxes are much smaller than the TEK.
We find that the PMK X1000 probe tips, bodies and comp box trimmers are much more delicate than the TEK.
We hope that PMK Germany service can support the bad probe and fix it.
Amicalment,
Jon
