Parameter:
Example:
Set the instrument into the front panel lockout state. The front panels controls cannot be
used.
LOWS
(Low Potential Output Terminals command) Selects whether or not the Calibrator front
panel NORMAL LO terminal and AUX LO terminal are internally tied together (default)
or are open. This feature is used for ac power, dc power, dual dc volts and dual ac volts
outputs. Once set, the Calibrator retains the LO setting until power off or reset.
Parameter:
Example:
Tie the front panel NORMAL LO and AUX LO terminals together.
LOWS?
(Low Potential Output Terminals query) Returns whether or not the Calibrator front
panel NORMAL LO terminal and AUX LO terminal are internally tied together (default)
or are open.
Response:
Example:
Returns OPEN when the Calibrator front panel NORMAL LO and AUX LO terminals
are not tied together.
MULT
(Multiply command) Multiplies the reference magnitude (as selected with the EDIT
command or default to the primary output). The reference magnitude is the present
reference in either direct mode or in error mode.
Parameter:
