The self-check alarm register indicates possible problems with the instrument hardware or setup
configuration. The hardware problems are indicated by the appropriate bits which are set whenever the
instrument fails self-test diagnostics or in the event of loss of power. The setup configuration problems are
indicated by the dedicated bit which is set when either configuration register is corrupted. In this event, the
instrument will use the default configuration. The configuration corrupt bit may also be set as a result of the
legal changes in the setup configuration since the instrument might implicitly change or clear other setups if
they are affected by the changes made.
Hardware fault bits can be reset by writing zero to the self-check alarm register. The configuration corrupt
status bit is also reset automatically when you change setup either via the front panel or through
communications.
5.8 Extended Data Registers
The following table lists all registers containing the data measured by the instrument. Notice that these
registers are arranged into groups which are not located at adjacent addresses. You can re-map these
registers into adjacent addresses to access multiple data from different data groups by using a single
request. Refer to Section 2.9 for information on the user assignable registers.
Along with the register address, the table shows for each data item its point identifier (ID). This is a one
word containing a data group ID in the high byte and the parameter offset in a group in the low byte. Point
IDs are used to specify input or output parameters whenever a data parameter specification is needed, for
example, when selecting analog output parameters or reading Min/Max log records.
