30216 - 30217:
Time Stamp
Dual-register representation of data packet time stamp.
Integer value (type defined as time_t) representing start date/
time in seconds since January 1, 1970.
30218 - 30219:
Sample Time
Dual-register representation of data packet sample interval
processed in units of seconds. Can be integer or float
depending on mode selected. The integer representation is
time in seconds multiplied by 100.
30220- 30221:
Data Packet Status
Values are defined in
30222 - 30223:
Flow Rate
Dual-register representation of the data packet flow rate in
milliliters per minute. Can be integer or float depending on
mode selected. The integer representation uses the scale
factor from register 30011.
30224 - 30225:
Volume
Dual-register representation of the data packet volume in
milliliters. Can be integer or float depending on mode
selected. The integer representation uses scale factor from
register 30012.
30226:
Location
Index of location value associated with data packet. Not used
for LiQuilaz II.
30227:
Number of Particle Channels
Processed as a variable since the LiQuilaz II can queue data
packets which were collected using a varying number of
selected channels. If a varying number of size channels are
processed, it is up to the host to track the sizes specified for
each data set or to delete the queued data after a size channel
adjustment.
30228:
Number of Analog Channels
Processed as a variable but fixed to a value of 1 for LiQuilaz II.
30229 - 30260:
Cumulative Particle Data
Dual-register representation of particle size counts. Currently
unused size channels will be loaded with a value of zero.
30261 - 30262:
Analog Data
Dual-register representation of the data packet analog value.
Can be integer or float depending on mode selected. The
integer value represents the scaled DC Light input multiplied
by 10000. Integer representation limited to a value between
-214748.3648 to 214748.3647.
