Hey EEVbloggers!
I have a new Rigol DS1054z that isn't correctly displaying / reading voltage. Am I doing something wrong?
I hooked up the output of a TEMS device (one of those zap zap medical things) to my DS1054z input. For some reason it says the channel is receiving more than 30 volts. However, my Fluke 87V says: Mean voltage = 2.5 VAC, Min voltage = 1.560 VAC, Max voltage = 3.457 VAC. The current is very low (on the order of 10^-2 A). The oscilloscope leads were on the 1X setting.
I trust the readings from my Fluke. I literally trust my life to that meter.
Is there a setting in the Rigol that is scaling the potential? I've scaled the *.csv data set to work with it in R - but I'd much rather just get good information without any scaling! In fact the *.csv output has a high value of "284," which is really confusing.
Thank you very much for your input!
Yay EEVBlog!!
