Calibration frequencies and calibration factors are associated in pairs—i.e., Calibration Frequency [1] and
Calibration Factor [1]— and must be sorted in ascending order, based on calibration frequency values, prior
to writing the values to the instrument. Therefore, Calibration Frequency [1] should be the smallest of all
calibration frequencies.

Important Two sets of 16-bit holding registers are provided (starting at 17001 and 8000). The
“8000” set displayed in parentheses in the table on page C-9 should be used with master
devices that require the holding registers to be in the range of 40000 to 49999.
