Part Number: SPIO-4
I am currently using the LMP91200 v188.8.131.52 software on Windows 10, and have the LMP91200EVAL board connected to the SPIO-4 board which is connected to my computer via USB. I am using a ph sensor from Accumet (Cat. #13-620-631), which is connected to the LMP91200EVAL board with the BNC connector to measure ph. There is also a stereo plug from the ph meter for temperature output which is not currently connected to the LMP91200EVAL board, so I am not expecting to be able to read the temperature with the current setup, just the ph.
When I run the software to measure ph I get the following error:
"Wait too long for the data, capture will stop. Possible Reason: Transfer size too large."
I get this error message when I have the following settings in the Measurement tab: Ph Measurement, Specified Temperature of 25.0 C, Display PH Value, and Run for 1 second.
If I run the software using the above settings except changing it to use the Measured Temperature I get the following error:
"Wait too long for the data, capture will stop. Possible Reason: Transfer size too small"
I am not sure if the error is being caused by my ph meter or the LMP91200EVAL board and SPIO-4 board. If the issue is not receiving a temperature reading from the ph meter, how would I go about connecting the temperature output to the LMP91200EVAL board? Or is there a better ph meter that is made to interface with these boards and the software? I looked on TI's website but could not find a ph meter to use with this.
