MEASure:CAPacitance? [{<
range
>|AUTO|MIN|MAX|DEF} [, {<
resolution
>|MIN|MAX|DEF}]]
Sets all measurement parameters and trigger parameters to their
for capacitance meas-
urements and immediately triggers a measurement. The results are sent directly to the instrument's out-
put buffer.

l
You can let autoranging select the measurement range, or you can manually select a fixed range.
Autoranging conveniently selects the range for each measurement based on the input signal. For fast-
est measurements, use manual ranging (autoranging may require additional time for range selection).
l
Autoranging (AUTO or DEFault), will generate an error if you specify a <
resolution
> because the instru-
ment cannot accurately resolve the integration time (especially if the input continuously changes). If
your application requires autoranging, specify DEFault for the <
resolution
> or omit the <
resolution
>
altogether.
l
Autoranging goes down a range at less than 10% of range and up a range at greater than 120% of
range. For capacitance measurements only, when autorange is off, the instrument does not report an
overload for readings greater than 120% of range. Overload only occurs when the algorithm times out
because the applied capacitance is too large for the algorithm to measure. If you apply a DC voltage or
a short to the input terminals in capacitance measurement mode, the instrument reports an overload.
l
If the input signal is greater than can be measured on the specified manual range, the instrument dis-
plays the word
Overload
on front panel and returns "9.9E37" from the remote interface.
