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
Command parameter:
<n> = -757.5 to 757.5
Reference for ACV
-1010 to 1010 Reference for DCV
DEFault
0 (All measurement functions)
MINimum Mininum value for specified function
MAXimum Maximum value for specified function
Query:
:REFerence?
Query reference for relative function
Descripton:
These commands are used to establish a reference value for the specified function. When reference
is enabled (:REFerence:STATe), the result will be the algebraic difference between the input signal
and the reference value:
Reading = Input signal
–
Reference
From the front panel, reference is called relative (REL).
The:REFerence <n> command is coupled to the :ACQuire command. The last command sent
(:REFerence <n> or :ACQuire) eatablishes the reference. When a reference is set using
the:REFerence <n> command, the REFerence? Query command returns the programmed value.
Conversely, when a reference is set using the:ACQuiry command, the:REFerence? Query
command returns the acquired reference value.
