Set the instrument into the front panel lockout condition. The front panel’s controls
cannot be used.
LOWS
Overlapped Coupled IEEE-488 RS-232 Sequential
x x x x x
(Low Potential Output Terminals command) Selects if 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.
When set, the Calibrator keeps the LO setting until power off or reset.
Parameter:
OPEN
(disconnect NORMAL LO and AUX LO terminals)
TIED
(connect NORMAL LO and AUX LO terminals)
Example:
LOWS TIED
Tie the front panel NORMAL LO and AUX LO terminals together.

when the Calibrator front panel NORMAL LO and AUX LO terminals are
not tied together.
MULT
Overlapped Coupled IEEE-488 RS-232 Sequential
x x x x x
(Multiply command) Multiplies the reference magnitude (as selected with the
EDIT
command or default to the primary output). The reference magnitude is the current
reference in direct mode or in error mode.
Parameter: <value> (multiplier expressed as a floating point number)
Example:
MULT 2.5
Multiply the reference that exists by 2.5, creating a new reference. For example, a
reference that exists of 1 V is multiplied to 2.5 V.
NEWREF
Sequential Overlapped Coupled IEEE-488 RS-232
x x x x x
(New Reference command) Sets the new reference to the current Calibrator output value
and exit the error mode (if selected). For example, you might edit the Calibrator output
with the
EDIT
and
INCR
commands, and then use the
NEWREF
command to establish a
new reference point and exit the error mode. This is the same as pressing the Calibrator
front panel

key.
Parameter: (None)
Example:
NEWREF
Set the reference value to the current Calibrator output value.
OLDREF
Overlapped Coupled IEEE-488 RS-232 Sequential
x x x x x
(Old Reference command) Sets the Calibrator output to the reference value and exit the
error mode (if selected). If editing the output with the
