CLOCK Sets the real-time clock.
CLOCK? Queries the real-time clock.
DBMZ_D Sets the power-up and reset default impedance used for dBm outputs (ac volts).
DBMZ_D? Returns the power-up and reset default impedance used for dBm outputs (ac
volts).
FORMAT Use with extreme care. Restores the contents of the nonvolatile memory device to
factory defaults.
LIMIT Sets the maximum permissible output magnitudes, negative and positive.
LIMIT? Returns the programmed output magnitude limits for voltage and current.
PR_RPT Prints the Stored, Active or CAL-Constant CAL_Report through either the HOST or
UUT Serial Port.
PRES_UNIT_D Sets the power-up and reset default pressure display units.
PRES_UNIT_D? Returns the power-up and reset default pressure display units.
REFCLOCK_D Sets the power-up and reset default for the reference clock source (internal or
through the 10 MHz IN BNC connector).
REFCLOCK_D? Returns the power-up and reset default for the reference clock source (internal or
through the 10 MHz IN BNC connector).
REFPHASE_D If two Calibrators are synchronized using 10 MHz IN/OUT, sets the power-up and
reset default phase difference between the NORMAL terminals on the slave
Calibrator and the NORMAL terminals of the master Calibrator.
REFPHASE_D? If two Calibrators are synchronized using 10 MHz IN/OUT, returns the power-up
and reset default phase difference between the NORMAL terminals on the slave
Calibrator and the NORMAL terminals of the master Calibrator.
RTD_TYPE_D Set the default Resistance Temperature Detector (RTD) sensor type.
RTD_TYPE_D? Returns the default Resistance Temperature Detector (RTD) sensor type.
SP_SET Sets the HOST serial port communication parameters and saves them in
nonvolatile memory.
SP_SET? Returns the HOST serial port communication parameters contained in nonvolatile
memory.
TC_TYPE_D Sets the power-up and reset default thermocouple type.
TC_TYPE_D? Returns the power-up and reset default thermocouple type.
TEMP_STD Sets the temperature degree standard, ipts-68 or its-90.
TEMP_STD? Returns the temperature degree standard, ipts-68 or its-90.
TLIMIT_D Sets the power-up and reset default for the time limit for -SC600 OVERLD mode to
stay in operate.
TLIMIT_D? Returns the power-up and reset default for the time limit for -SC600 OVERLD
mode to stay in operate.
UNCERT? Retums specified uncertainties for the present output. If there are no specifications
for an output, returns zero.
