I'm not sure I would recommend trying to replicate all the ACV/DCV/Ohms/Amps/mAmps ranges 
of a $1 Centek DVM from Harbor Freight.
But instead of spending the extra $11 bucks on a DVM with a capacitance range, it might be worth
building this capacitance meter into your Raduino:

Select it with a menu option.

It is relatively easy to build up an Arduino with LCD display to display voltages that are
presented to one, or more, of the ADC inputs.  This gives you a basic 5V range that can
be increased with dividers.
