Can anyone kindly help with the Calibration and mode of operation of a E201-C pH Electrode?

Please i need the Calibration and mode of operation of a E201-C pH electrode, its very urgent, I've searched everywhere on the internet but cant get anything close. I need its calibration and mode of operation, it doesn't seem to be delivering any voltage signal when inserted into a solution. Thanks in anticipation.

What sort of meter do you have attached to it?

An Analog circuit as shown below

Do you know that that circuit works? Do you have an actual meter to test your probe with? Is the solution you are testing a known value or is it just plain water? Water should be OK, but if that doesn't work, add a little table salt to it.

From what I could tell, your probe is no different than typical probes. Here's a YouTube on how to calibrate:

Thanks alot
