Re: Current Measurement

Thanks, I wasn't really thinking about spikes. Where did you find that they are good for 500% over their measrement range?

We are interested in current measurement mostly for use in traction control so I am guessing large spike due to stalled drive motors may not be a huge problem this year. I am assuming that a jammed or locked mechanism driven by a CIM would stall the motor long enough for the breaker to kick out but I could see that brief large spikes would occur when say a CIM shifts from full forward to full reverse. Any thoughts as to if these Phidgets would smoke on a brief spike like this or just max their reading?
