40020 ASCII string Model Name char[10], char [11]
40021 ASCII string Model Name char[12], char [13]
40022 ASCII string Model Name char[14], char [15]
40023 unsigned integer Flow Rate. Divide by 100 to get rate in CFM. For example,
100 = 1CFM.
40024 signed integer Record Count. Total number of records stored in the counter.
40025 signed integer Record Index. Zero based index to data in 30xxx register
series. Must be lower than the record count (register 40024).
Set this index to expose a counter’s record in the 30xxx
registers. Set to -1 to retrieve last record stored in the counter.
40026 unsigned integer Location number.
Particle Counters
: Specifies location of Particle Counter. Must
be 1 to 200 (maps to location names associated with registers
40200 - 40999).
Manifold Controller
: Specifies Manifold position. Values 1-32
for the Universal Manifold and values 1-6 for the MiniManifold
Controller moves the arm to that position on the manifold.
Value 0 moves arm to Home position.
40027 signed integer Real Time Clock (RTC) [high]. Updates instrument’s real-time
clock. Works in conjunction with 40028. Displays date and
time, in number of seconds since midnight, 1/1/1970. Can be
generated by ANSI C/C++ time() function.
40028 signed integer Real Time Clock [low]
40029 unsigned integer Initial Delay [high]. Works in conjunction with 40030.
Number of seconds to wait before starting the first sample. Max
value is 359,999, which equals 99h 59m 59s.
40030 unsigned integer Initial Delay [low]
40031 unsigned integer Hold Time [high]. Works in conjunction with 40032. Number
of seconds to wait between sample periods. Max value is
359,999, which equals 99h 59m 59s.
40032 unsigned integer Hold Time [low]
40033 unsigned integer Sample Time [high]. Works in conjunction with 40034.
Number of seconds to sample. Max value is 86,399, which
equals 23h 59m 59s.
