MEASure[:VOLTage]:{AC|DC}? [{<range>|AUTO|MIN|MAX|DEF}, [{<resolution>|MIN|MAX|DEF},]]

(@<ch_list>)

AC voltage measurements only supported on DAQM901A multiplexer module.

DC voltage measurements only supported on DAQM900A, DAQM901A, DAQM902A, and DAQM908A mul-

tiplexer modules.

Resets all measurement parameters on the specified channels to their default values. Then, configures the channels

for ACand DCvoltage measurements and immediately sweeps through the specified channels one time (inde-

pendent of the present scan list). The results are sent directly to reading memory and the instrument's output buf-

fer. This command redefines the scan list.

Parameter Typical return

<range>: {100 mV|1 V|10 V|100 V|300 V}.

Default:AUTO

(none)

AC voltage: Optional and ignored; fixed at 6½ digits

DC voltage: 1 PLC

Configure DC voltage measurements using the 10 V range with 1 mV resolution on channel 101. Then make and read one measurement:

MEAS:VOLT:DC? 10,0.001 (@101)

Typical Response:+8.54530000E+01

– When you specify a range of channels with this command, any channels that are invalid will be ignored (no error

will be generated) but the selected function must be valid for at least one channel in the range, or an error will be

generated.

–

You can allow the instrument to automatically select the measurement range using autoranging or you can

select a fixed range using manual ranging. Autoranging is convenient because the instrument decides which

range to use for each measurement based on the input signal. For fastest scanning operation, use manual ran-

ging on each measurement (some additional time is required for autoranging since the instrument has to make a

range selection).

–

If you select autoranging (by specifying "AUTO" or "DEF") and specify a discrete value for the <resolution> para-

meter, the integration time selected based on the default range for the function (1 A for AC or DC current meas-

urements).

– Autorange thresholds:

Down range at: <10% of range

Up range at:>120% of range

– Because this command resets all measurement parameters on the specified channels to their default values, be

sure to send the CONFigure command before setting any other measurement parameters.
