Hi, we are using a newly purchased 3205. The Channel B over range warning came on but just prior to that the voltage being measured was 4 volt. There may have been a transient higher voltage but we did not see such. We cannot clear this over range warning. Channel B no longer shows a trace from the signal generator. We have tried all apparent options or configurations. Channel A is OK.
We tried two PCs. We downloaded the latest Pico 6 R6.2.2
BTW, we were measuring something that has been previously measured. So no wild voltage spikes were expected nor were they seen in the few pulses monitored before Channel B stopped working.
Is the Picoscope hardware broken?
