Hi, I am using the CN0359 Rev. C Conductivity Measurement System. I am using it with this conductivity sensor from IST: LFS1305
The sensor requires the following:
- Excitation voltage: <0.7Vpp
- Excitation frequency: 100Hz to 10kHz
- Cell constant = 0.86/cm
Based on the medium I am using, my readings should be in the range of μS/cm, but instead I am in the mS/cm range. I do occasionally get the right reading, but it is intermittent.
My questions are:
- When setting the excitation voltage, is this the Vp or the Vpp? For example, if i set it to 0.7V, does that mean the Vpp is 0.7V or 0.35V?
- What could be the possible cause of my intermittent values?
- For context, when I do get good readings the excitation voltage is set to 0.6V, frequency is 820Hz, and setup time is around 8% and hold time around 5%.
Thanks!
