Command Parameter Unit Remarks
CALibration
:DATA[?] <calibration data set as definite length block>
:LENGth? Bytes Query only
:ZERO
:AUTO[?] OFF | ON | ONCE
CALibration:DATA[?] <calibration data set as definite length block>
CALibration:DATA is used for writing a calibration data set in the flash memory of the sensor.
The query yields the calibration data set currently stored in the flash memory as a definite length block.
CALibration:DATA:LENGth?
CALibration:DATA:LENGth? yields the length in bytes of the calibration data set currently stored in the
flash memory. Programs that read out the calibration data set can use this information to determine the
capacity of the buffer memory required.
CALibration:ZERO:AUTO[?] OFF | ON | ONCE
The commands CALibration:ZERO:AUTO ON and CALibration:ZERO:AUTO ONCE zeroes the three
measurement paths of the sensor. For this purpose, the test signal must be deactivated or the sensor
disconnected from the signal source. The sensor automatically detects the presence of any significant
power to be measured. This causes zeroing to be aborted and error message NRPERROR_CALZERO
to be output. The CALibration:ZERO:AUTO OFF is ignored. Zeroing takes four seconds at a minimum,
but at least as long as the selected averaging filter needs for settling (only fixed-filter mode).
