[Linked Image]DSP technology is very good.I'm not against using DSP.but look here(https://www.ebme.co.uk/forums/ubbth...000d-7000-are-terrible-testers#Post76806)
Fluke IMPULSE 6000D DEFIB analyzer Used TMS320F2812GHHA,It is a DSP chip.Frequent failures in actual use and difficult to repair
There is also 6000D, which cannot work when the battery is fully charged. You must disconnect the battery and reset it. The battery is installed at the bottom of the motherboard, and it is a Ni-MH battery.
At first, I guessed that my 6000D may have been used for a long time (about 5-7 years),So I bought a 7000, also made by flukebiomedical, but still the same,The new 7000 defibrillation analyzer has only been used for 3 days, and it cannot be turned on when it is fully charged. It is necessary to disassemble the main board, separate the battery from the main board, and it is normal again.
So I think this is an inherent failure of the impulse-6000d-7000 and cannot be repaired。

So sometimes the latest tester from the best known manufacturer isn't the best

But the classic Bio-Tek QED-6, it has been working very stable, only using a 9V battery to work
