Query:
:RANGe[:UPPer]?
Query measurement range of the current function.
Description:
This command is used to manually select the measurement range for the specified measurement
function. The range is selected by specifying the expected reading as an absolute value. The
instrument will then go to the most sensitive range that will accommodate that expected reading. For
example, if you expect a reading of approximately 20mV, simply let the parameter (<n>) =0.02 (or
20e-3) in order to select the 200mV range.
:AUTO <b>
Command syntax:
:VOLTage:AC:RANGe:AUTO <b>
Set auto range for ACV
:VOLTage:DC:RANGe:AUTO <b>
Set auto range for DCV
Command parameter:
<b> = 1 or ON
Enable auto range
0 or OFF
Disable auto range
Query:
:AUTO?
Query auto range (ON or OFF)
Description:
These command are used to control auto ranging. With auto ranging enabled, the instrument
automatically goes to the most sensitive range to perform the measurement.
The auto range command (:RANGe:AUTO) is coupled to the command that manually selects the
measurement range (:RANGe <n>). When auto range is enabled, the parameter value for :RANGe
<n> changes to the automatically selected range value. Thus, when auto range is disabled, the
instrument remains at the automatically selected range. When a valid :RANGe <n> command is
sent, auto ranging disables.
:REFerence <n> Commands
:REFerence <n>
Command syntax:
:VOLTage:AC:REFerence <n>
Specify reference for ACV
:VOLTage:DC:REFerence <n>
Specify reference for DCV
