The timestamp field indicates when the data record was recorded.
Timestamps are stored as the number of seconds since 1/1/1970, the
Unix time epoch. This value can be written directly into a C/C++
time_t data type to be used by ANSI C time functions.
Device Status Word
The registers used for the Sample Status Word are 30007-30008 to
sample status. The bit order of the Device Status Word is 7 to 0 (right
to left), where bit 7 is the most significant bit and bit 0 is the least
significant bit. The bits within the Device Status Word are flagged to
indicate particular conditions of the currently indexed data record. If
multiple states occur, the bits are added together. For example, a
Flow Alert and a Particle Overflow would return a value of 6 in
register 30008 (bits 1 and 2 are set TRUE).
LASER Alert Status
0 = LASER is good 1 = LASER Alert
0 = Flow Rate is good 1 = Flow Rate Alert
Instrument Service Status
0 = Working correctly 1 = Instrument malfunction detected.
Particle Threshold Exceeded Status
0 = Threshold not exceeded 1 = Threshold exceeded
Table A-15 Device Status Word

regardless of the
