Square Wave Votammetry optimization

Hi,

  Could you monitor voltage across CE and SE which is the potential applied to load for this current capture period? 

I am using code (ad5940) available on github. Here I am getting only index v/s current using realterm.

Can you monitor voltage across CE and SE on oscilloscope?

Till now, I didn't check. I will check and let you know. Thank you

Sorry for the late reply. I have monitored voltage across CE and SE on the oscilloscope. Its showing near the range of +1.2 to -1.3V. I want to run the device for the potential range of -1.2 to 0.4 V. How can I arrange the potential range? Because of the wrong potential alignment, I am not able to get the oxidation peak of the analyte. On CHI, I am getting good current response. Please help.

Hi,

you may set

pRampCfg->RampStartVolt = -1200.0f; /* Measurement starts at 0V*/
pRampCfg->RampPeakVolt = 400.0f; /* Measurement finishes at -0.4V */
pRampCfg->VzeroStart = 1500.0f; /* Vzero is voltage on SE0 pin: 1.3V */
pRampCfg->VzeroPeak = 1500.0f; /* Vzero is voltage on SE0 pin: 1.3V */
