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.
Parameter
(none)
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 over-
load.
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.
