This object indicates whether the actual values read from EEPROM internally within an implementation are already calibrated to the appropriate units (Volts, mA, dB, etc), or whether these values are first converted to appropriate units. The value external(2) indicates that the values as read from EEPROM must be converted. Note that this is only an indication of what happens internally within an implementation, and does not have any effect on the values of other columns in this table.
