Operators Manual
Examples:
Returns the symbolic name of the single or first output, and return the symbolic name of
the second output (0 if there is no second output).
RANGELCK
(Range Lock command) Locks in the present range, or selects auto ranging for dc
voltage and dc current single outputs. The range automatically unlocks if the output
function changes, for example from dc volts to dc current. When RANGELCK is on, this
is equivalent to the softkey range lock showing locked. When RANGELCK is off, this is
equivalent to the softkey range lock showing auto.
Parameter:
Example:
Set the range lock off to allow autoranging for dc volts or dc current.
RANGELCK?
(Range Lock query) Returns whether or not the preset dc volts or dc current single
output range is locked.
Response:
Example:
Returns OFF when the range for dc volts or dc current is not locked (autoranging
enabled).
