Trigger "External Calibration"
CAL?
Triggers an external calibration event, including the "SET" feature used for local
calibration.
Nrf
A numeric value representing the "SET" calibration value. This is used as the target for
the actual measured value. The difference between these two values is used to determine
the calibration factors. The Nrf value is rounded to 8.5 digits resolution.
If the Nrf data element is included then phs is required. The number must conform to the
limits required for the function being calibrated.
If the program header separator (phs) and Nrf are omitted, the instrument assumes that
the nominal calibration point value is the target for the actual measured value.
Response
(Nr1) The value returned identifies the success (0) or failure (1) of the calibration
exercise:
Execution Errors
If calibration is not enabled, or if the number used is incompatible with the setting being
calibrated.
Select Spot Frequency
Selects the spot frequency store to be used by the calibration trigger (ACV only).
SELSPOT
Allows the user to select a spot frequency on the active ACV range by entering the spot
number. The user then enters the target value that calibrates the selected spot.
1st Nrf
A decimal numeric data element representing the selected spot frequency store, from
1 to 6.
2nd Nrf
A decimal numeric element that represents the SET value to be applied. This value is
preceded by the "SET" element. This is used as the target for the actual measured value.
The frequency that will be assigned to the spot number, is allocated by the Multimeter's
frequency detector. To complete the calibration a calibration trigger is required (CAL?).
Numbers that exceed the required resolution will be rounded.
Execution Errors
If calibration is not enabled, or if the 1st Nrf is out of range.
