Meter for measuring cable capacitance


Hello! I looking for a recommendation for a suitable capacitance meter. I own a Fluke 117 and although it has settings to measure capacitance, it doesn’t read cable(guitar cable) capacitance. Just reads “1” regardless of cable length. Not sure if this is because it doesn’t have a pico farad setting. Not sure. 
 

Thanks in advance!

Many capacitance meters HATE to be shorted. Capacitance of 1m wire should only be figured using an oscilloscope.

to gain necessary impedance safe for capacitance meter, you should have around few hundreds of meters of same wire tested as positive and negative terminal. 1m is waaay too short!!

 

It is “distributed capacitance” - you cannot measure it directly.  What you measure is a combination of capacitance, inductance and resistance of the cable.  I wouldn’t trust the meter, even when it displays sensible numbers.  There might be more complicated ways of multiple measurements at different frequencies and calculations, but I’ve never done it.  The best would be to get nominal capacitance per foot of the cable from manufacturer and adjust it (multiply) for the length.

Measure by putting a known capacitor (value) across the end of the cable and subtracting its value from the total.
