Calibration Constant Information
The constants in these tables are arranged by group. Each group is stored as a
block in nonvolatile memory. The value given for each constant in this list is the
default assigned before the instrument is first calibrated. Defaults are reinstated if
you perform a format of the EEPROM ALL or CAL areas.
