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:
<value>
Example:
MULT 2.5
Multiply the existing reference by 2.5, creating a new reference. For example, an existing
reference of 1 V is multiplied to 2.5 V.

IEEE-488
NEWREF
(New Reference command) Sets the new reference to the present Calibrator output value
and exit the error mode (if selected). For example, you might edit the Calibrator output
using 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 N key.
Parameter:
(None)
Example:
NEWREF
Set the reference value to the current Calibrator output value.
x
IEEE-488
OLDREF
(Old Reference command) Sets the Calibrator output to the reference value and exit the
error mode (if selected). If editing the output using the EDIT and INCR commands and
you want to return to the reference value, use the OLDREF command. If editing the
output and you want to make the edited value the new reference, use the NEWREF
command.
Parameter:
(None)
Example:
OLDREF
Set the output to the existing reference value, clearing editing changes.

IEEE-488
ONTIME?
(Calibrator On Time query) Returns the time in minutes since the Calibrator was most
recently powered up.
Response:
<minutes>
Example:
ONTIME? returns 47
Returns the time since the Calibrator was last powered up: 47 minutes.

IEEE-488
*OPC
(Operations Complete command) Sets bit 0 (OPC) of the Event Status Register to 1
when all pending device operations are complete. Also see the *ESR? command.
Parameter:
(None)
Example:
*OPC
Set bit 0 of the Event Status Register to 1 when all pending device operations are done.
