MEASure[<chan>]:ARRay[:VOLTage][:DC]?

Parameters

Parameter	Parameter	Range of	Default
Name	Type	Values	Units

chan	numeric	1 2	none

size	numeric	1 7 to 524288	none

expected	numeric	-102.30 to 102.35	volts
value		DEFault
		MINimum MAXimum

resolution	numeric	.00005 to .05	volts
		DEFault
		MINimum MAXimum

input port	numeric	13 with MEASure1	none
		24 with MEASure2
		1 and 2 are single ended
		3 and 4 are differential

The maximum size parameter will be 524284 if the battery is enabled instead of 524288.

For expected value, MINimum selects the 0.100 V range and MAXimum selects either the 1.0 volt range (single ended ports) or the 100 V range (differential ports). DEFault selects 1V.

For resolution, MINimum, MAXimum, and DEFault select the same value.

Settings Maximum expected value settings per range are shown in the following table, along with the resolution associated with each range. The highlighted area shows the setting used when the expected value is not specified or DEFault is used.
