(Format command)
Use with extreme care.
Restores the contents of the nonvolatile
memory device to factory defaults. The memory holds calibration constants and setup
parameters. You lose all calibration data permanently. The CALIBRATION switch on
the rear panel of the Calibrator must be set in the ENABLE position or an execution error
occurs, except for
FORMAT SETUP
.
Parameter:
ALL
(replaces the whole contents with factory defaults)
CAL
(replaces all cal constants with factory defaults)
SETUP
(replaces setup parameters with factory defaults)
Example:
FORMAT SETUP
Replace the setup parameters with the default setup values (below). (The
FORMAT ALL
command is the same as
FORMAT CAL
and then
FORMAT SETUP
.) The
FORMAT
SETUP
command also clears the
*PUD
string (see the
*PUD
command) and
SRQSTR
is
set to “SRQ: %02x %02x %04x %04x” (see the
SRQSTR
command) and
SPLSTR
is set
to “SPL: %02x %02x %04x %04x” (see the
SPLSTR
command).
