10-4 Signal Oriented Measurement Commands
:READ[1]?
channel (#1)
:READ[1]:ARRay?
battery channel (#1)
:READ2?
channel (#2)
:READ2:ARRay?
charger channel (#2)
The :READ? command is used to trigger and return a single averaged reading, and the
:READ:ARRay? command is used to trigger and return an array of readings for the currently
selected function on the applicable channel (the battery channel being the default and the charger
channel requiring a 2 to be appropriately added to the command string). The averaged reading
or reading array is sent to the computer when the power supply is addressed to talk. The averaged
reading is displayed on the front panel. The front panel does not show an array of readings, only
the average of an array. All :READ commands apply to the presently selected function.
The number of readings to average or put in an array is set using the :SENSe:AVERage (for
voltage, current and DVM readings) or :SENSe:PCURrent:AVERage (for pulse-current
readings) command. See Sections 2 and 3 for details.

1. READ? and READ:ARRay? readings are always sent in exponent form.
2. There are no AVERage commands for long integration measurements. The array
size for long integration readings is fixed at one. Therefore, both READ? and
READ:ARRay? will return a single long integration reading.
