‘d’ - Followed by 4 numbers.
Reverse Rough Close Delay (D7) in Tenths of seconds.
(e.g. 0001 = 0.1 seconds)
(e.g. 0142 = 14.2 seconds)
This field did not exist In the serial stream in software revisions
prior to
Rev. 4.1. However, is was present on the MS-40 user panel and

‘g’ - Followed by 6 numbers. (first 5 are the leak rate and the last is reject
status). Previous Test Final Leak Rate Value & Reject Status measured
in atm-cc/sec or mbar-l/sec. See ‘H’ for reject status values. This is the
leak rate value and reject status of the previous leak test cycle just prior
to the termination of the test. It is used for data logging.
(e.g. 057082 = 5.7 x 10-8 atm-cc/sec & Accept or Pass)
(e.g. 100103 = 10.0 x 10-10 atm-cc/sec & Reject or Fail)
This field did not exist In the serial stream in software revisions prior to
Rev. 4.2.

Packets ‘C’ through ‘I’ are sent all the time. Packets ‘A’ and ‘B’ are
only sent when necessary. Packets ‘L’ and ‘N’ are send every third
time after packet ‘I’. Packets ‘J’, ‘K’, and ‘O’ through ‘g’ are sent
every 33 times after packets ‘L’ and ‘N’.
