USB Oscillocope and higher voltages

I was wondering if it were possible to mesaure 24 volts DC with the oscilloscope?· I thought someone had asked·a similar·question before but I was unable to find the thread.

Thank you
Steve

    I don't know about the parallax one - but usually they read to about 20v with standard probes - but you can usually buy higher voltage probes for mains stuff for example. I would guess the Parallax website would give the spec of theirs....

    The current USB oscilloscpe does not directly support measuring voltages of 0-24V, you can use a precision divider to drop the voltage to an acceptable range (at the expense of the input resistance of course).
