CONFigure?
Returns a quoted string indicating the present function, range, and resolution. The short form of the func-
tion name (CURR:AC, FREQ) is always returned.

Return the present function, range, and resolution:
CONF?
CONFigure:CAPacitance [{< range >|AUTO|MIN|MAX|DEF} [, {< resolution >|MIN|MAX|DEF}]]
Sets all measurement and trigger parameters to their
specifies the range.
<range>: {1 nF|10 nF|100 nF|1 µF|10 µF|100 µF}. Default:
AUTO.
<resolution>: optional and ignored; fixed at 4½ digits.
Configure capacitance measurements using the 1 µF range. Make and read two measurements:

Typical Response:+3.01574316E-10,+3.01659030E-10
You can let autoranging select the measurement range, or you can manually select a fixed range.
l
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).
Autoranging (AUTO or DEFault), will generate an error if you specify a < resolution > because the instru-
l
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.
Autoranging goes down a range at less than 10% of range and up a range at greater than 120% of
l
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.
If the input signal is greater than can be measured on the specified manual range, the instrument dis-
l
plays the word Overload on front panel and returns "9.9E37" from the remote interface.
