I recently got a wheestat from public lab, version wheestat 5. I am getting strange readings. I have posted a cv diagram. I get the same diagram whatever solution or electrodes i use (at this volts). Also, at the voltage limits the
negative-->positive and the positive-->negative, as shown. I have tried every other aspect of the mode bar and everything is strange. I tried different versions of the software and again the same diagrams. I have checked the continuity of the electrodes and it is ok. What may be the problem?
