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.
