bit 7: alarm 2
1 if alarm 2 is ON
bit 6: alarm 1
1 if alarm 1 is ON
bit 5: low flow
1 if there is a low flow error
bit 4: plasma status
1 if there is a plasma off error
bit 3: system status
1 if there is a low flow, plasma off, underscale
or overscale error
bit 2, and 0: range in use
001 = range 1 (ex: 0-1 or 0-10 ppm)
010 = range 2 (ex: 0-10 or 0-50 ppm)
100 = range 3 (ex: 0-100 ppm)
Each value is separated by a TAB character. The end of one transmission
(packet or frame) is indicated with a carriage return.
The checksum is the arithmetic sum of every transmitted byte (excluding TAB
bytes). The checksum may be used to verify the data integrity.
Example
: the ppm value is 40.1, the flow is 75.0 ml min
-1
(75 cc/min), the flow
counts are 8388600, the cell counts are 190011, the range used is the first one
(0-1 ppm), there are no alarm, but there is a low flow error. The data sent in
ASCII is:
