According to the table in Appendix A, the Block Type ID has the value "16".
This parameter indicates that the overrange or underrange of the Hot Cathode Ion
Gauge instance is exceeded.

Reading
Invalid
If the instance is operated in its overrange or underrange, the corresponding bit
and additionally the bit "Reading Invalid" is set.
If an error occurs, the bit "Reading Invalid" as well as the corresponding error bits
in Device Block (ID 26, 27, 28 Device Block) are set.
This parameter indicates the detectable errors occurring in connection with the BA
measuring part. The present implementation allows detection of one error.

1)
Electronics Failure includes a sensor error.
The Sensor Alarm bits defined here are copied into the Device Block ID 27 in the
"Device Exception Detail Alarm" range of the BA measuring part.
