B-6 Model 3772/3771 Condensation Particle Counter
SCM Set the operating mode. Model 3771 will not go into SMPS
mode.
Params: 0 => Concentration
1 => Totalizer
2 => SMPS
Example: SCM,0 (sets operating mode to concentration)
STS Set saturator temperature
Params: c => 0.0–50.0
Example: STS,39.0 (changes the saturator set point to
39.0 degrees C)
STC Set condenser temperature
Params: c => 0.0–50.0
Example: STC,22.0 (changes the condenser set point to
22.0 degrees C)
STO Set optics temperature
Params: c => 0.0–50.0
Example: STO,40.0 (changes the optics set point to 40.0
degrees C)
SAWR Set the auto water removal function on/off
Params: 0–Off
1–On
Example: SAWR,1 (turns on water removal)
SVO Set analog output voltage
Params: v => 0.000–10.000
Example: SVO,4.482 (sets the output voltage at 4.482
volts)
SAO Set analog output voltage proportional to concentration.
The analog output is 0 to 10V.
Params: 0 => Off
1 => 1E1
2 => 1E2
3 => 1E3
4 => 1E4
5 => 1E5 (CPC100 only)
Example: SAO,4 (A concentration reading of 1E4 will
equal 10V)
