Thanks for the answer, yes i soldered all suggested components (also a dac902) on the pcb, double checked everything. I see activity on the databus of the DAC, I see no clock signal on pin28 of the DAC....
Microcheap:
Have you soldered the R65 resistor (5.11k) too?


aRGee:
yes, I soldered them all, here is my heavely fluxed proof:)

Hi everybody, it works finally. I ordered a new DAC from the wellknown seller. Now he's 50 cents more expensive:)   I received one with a much better print then the old one. I changed the DAC on the PCB, changed R65 to 560 ohm and burned the firmware from the circuitspecialist (found in this threat). Everything works fine now, the meter behaves like a 2d72. Everybody thanx for the replies. Regards, Robert
