Hantek 2000 series - 2C42/2C72/2D42/2D72

Thank you, Microcheap. I can confirm. It is possible to turn 2d42 to 2d82 using DFU firmware update. And I can confirm that all "automotive" features are just presets. Even CAN bus analyzer... just scope with timing/voltage preset.... be careful if you are going to buy 2d82 because of CAN bus analysis. There is no data parser, no id monitoring.
Firmware from AxGxP is better.

In ealier versions of the 2D82 firmware there was very nice probe menu with current clamps etc. Now you can only choose these in diagnosis mode.

Hi,

I think I have put voltage on the terminals when the meter stand in Ohm After opening I have seen 2 o resistors on the underside of the CS7721CN chip above the banana bushes. which are burned. Is it possible to send me a detailed picture of that part of the print, so I can put on new parts?  It is R14 and R 15 as far as I can see

Tanks a lot

Microcheap:
If only the resistors are burned you are lucky, it's likely that you have damaged the dmm chip. Anyway, if you want to try to repair it, I opened up mine to check the resistors values: R14 is 10K 1% and R15 is 1K 1%.

I've tried to take a picture as well, it is not great but it may help.



Just curiosity, what was the voltage you were measuring?

Rien:
Hi Thanks for your fast response.
Yes I think You are right, but I wil give it a Try. All other funktions are working and ok, even the Resistance obove 50K. When I try to mesure 10 K for a very short time the value is displayed.
I was to fast trying the Meter before I have give a good look at the menue. The voltage was 220 V alternating :-\

Have done , but the result is not good  47r r is read 51r 330r = 360r  460r = 5,10K  510r = 5.6K  2k2 = 21 k 3k3 = 3.6k 4k7 = 4.6k 5k = 5k  50k =50k 200k =280k
So i can forget the measuring of Resistance  with this meter. but my own fault.

I was not happy with the result, so I have measured on the resistors and I came to the conclusion that they were connected to each other on the processor side, a small connection of tin I remove that, and guess, everything is working now.   But what a delicate job for an old men
