I have an old ADC-16 on which I have used the +5 V output and a serial regulator to provide a an accurate 2.5 V source for my sensors.

I have just purchased a new ADC-16, that also has a 2.5 V output.
What is the accuracy of this 2.5 V output and how many milliamps can it supply?

Hello Ivan,

Thank you for your post.

Both of these outputs are not intended as driving outputs. The 2.5v O/P is a reference voltage so any load on it could skew your readings.

The 5v O/P was initially rated at 2mA.

If you are looking to drive sensors, you should use an external supply.

Best regards,
Michael

Dear Sir,

Good Day,

I have bought the ADC16 Data Logger with its terminal board.
I am working in Potentiometric and Amperometric Sensors to measure the potential at Zero Current for the potentiometry and the current for Amperometry. I want to know the full details of circuits design “for example the suitable resistors Ra and Rb and other designs” for measuring these previous parameters and the required devices for its connection because I tried this from the manual of the instrument and it does not work.

Your co-operation in this matter will be highly appreciated.

I look forward to hearing from you.

Kind regards, Dr. A. Kamel

Hi

Thank you for your post.

I am not too sure what you mean, but if you are talking about a potential divider then you can find many diagrams of this on the internet.

Best Regards
