    hi Chris, sorry about the delay. voltage shown in the scope display seem to cliped at ~10VDC. my meter will show 15V and the scope will only display 9.5.

    ·· That is no error, the Scope can read +10V through -10V, but will not do over +/-10V (20Vpp). ·You would need to use a resistor divider to scale the voltage down to see it on the scope.· Take care.
