We had bought the oxygen electrode recently and got it connected to a PC using ADC- 16. After installing the software, i had followed the instructions given in the manual. One USB cable connects the ADC- 16 and the comp. The other cable connects the ADC- 16 and the oxygen electrode. Now in the Picoscope... it is mentione to go to File/Setup/Converter and select USB-PP1. But before selecting USB- PP1 we have to select ADC- 16 which was not found in the options given there. Please suggest me what I have to do? Waiting for the earlier response...
