communication. Addresses 1–127 select the RS-232 port and addresses 128–255
select the RS-422 port.
F4 – ComPara zn The setup parameters for the Baud Rate, Stop Bits, and Parity of the serial communication
port, where ‘z’ = 1..3 and where ‘n’ = 0..3.
n = 0..3 Baud Rate Stop Bits Parity
z = 1 z = 2 z = 3
0 9600 Invalid None
1 4800 1 Odd
2 2400 1.5 None
3 1200 2 Even

To reset the analyzer, take all necessary safety precautions and then press
‘•’ and ‘Ent’ simultaneously.
F4 0 TStPtz ** The control Set Point for the four temperature zones, where ‘z’ = 1..4. If the Set Point is
‘0’, that zone is not used. The zones are:
1 = Sample Line
2 = Vent (sample return) Line
3 = ASR900 Probe (or SKO)
4 = Oven
F4 1 Kpz ** The Proportional term of the PID temperature control algorithm for each temperature
zone, where ‘z’ = 1..4.
1 = Sample Line (default = 10.00 %)
2 = Vent (sample return) Line (default = 10.00 %)
3 = ASR900 Probe, or SKO (default = 10.00 %; 0.00 % if not used)
4 = Oven (default = 10.00 %)
F4 2 Tiz ** The Integral term of the PID temperature control algorithm for each temperature zone,
where ‘z’ = 1..4.
1 = Sample Line (default = 1000.00 seconds)
2 = Vent (sample return) Line (optional, default = 1000.00 seconds)
3 = ASR900 Probe, or SKO (default = 1500.00 seconds; 0.00 seconds if not used)
4 = Oven (default = 5000.00 seconds)
F4 3 Tdz ** The di󰀨erential (Derivative) term of the PID temperature control algorithm for each tem-
perature zone, where ‘z’ = 1..4.
1 = Sample Line (default = 0 seconds)
2 = Vent (sample return) Line (optional, default = 0 seconds)
3 = ASR900 Probe, or SKO (default = 0 seconds)
4 = Oven (default = 0 seconds)
