MEASure:{RESistance|FRESistance}? [{<range>|AUTO|MIN|MAX|DEF} [, {<resolution>|MIN|MAX|DEF}]]
Sets all measurement and trigger parameters to their
or 2-wire (RESistance) measurements, and immediately triggers a measurement. The results are sent dir-
ectly to the instrument's output buffer.
<range>: 100 Ω, 1 kΩ, 10 kΩ, 100 kΩ, 1 MΩ, 10 MΩ, 100 MΩ, 1
GΩ, AUTO,or DEFault. Default: AUTO.
Resolution Table
<resolution>: See
NPLC.
The default is equivalent to 10 PLC.
Specify <resolution> in the measurement's units (V, A, Hz, Ω,
and so on).
Configure 4-wire resistance measurements using the 100 Ω range with default resolution. Then make and
read one measurement:
MEAS:FRES? 100
Typical Response:+8.54530000E+01
The 1 GΩ range applies only to the 34465A and 34470A.
l
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.
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.
