Troubleshooting an Inoperative Analyzer
If Using Defaults <N> is displayed
A dead BT101 battery will cause the loss of all correction-factor and
correction-constant data. When the data stored in memory is lost, the
analyzer substitutes the default-correction data stored in ROM and
performs the instrument-preset routine. The message
Using Defaults <N> will appear on the analyzer display (where N is
an integer that represents a code that was used during the development
of the analyzer firmware).
If the battery is dead, replace the battery as described in Chapter 7
then reload the correction constants as described in Chapter 3 of this
service guide.
