Table 6-5. Commands (cont.)
Overlapped long-term command, ignored if not in remote.
Calibrates the internal references for the main output functions based on comparison to
an externally-applied standard. To calibrate the Calibrator, the controller must send a
CAL_TEMP command, a sequence of CAL_REF commands (one for each external
standard), followed by a CAL_ADJ command, then a CAL_STORE command. These
commands must be in the same sequence as in the example. Note that the CAL_STORE
command requires the security passcode. To only collect performance data, use this
command without a CAL_STORE.
The value of the external standard attached to the Calibrator binding posts. The value
and units of the parameter tell the Calibrator which calibration procedure to do.

CAL_SECURE ON
Overlapped command, ignored if not in remote.
Starts a calibration of a range. This command causes the Calibrator to source the
calibration magnitude specified by the second parameter for the range specified by
the first parameter. To calibrate a range, the controller must send commands in the
same sequence as in the example.
1. The range identifier of the range to calibrate from Table 5-4, or the keyword
NULL or STORE.
2. (Only if parameter 1 is the range mnemonic) The calibration magnitude for the
Calibrator to source. Must be 45% to 95% of the range specified.
3. (Optional; only if parameter 1 is the range mnemonic) The frequency of the
Calibrator output with optional multiplier and units.
