Teledyne API Ultrafine Particle Monitor - Model 651 Instrument Operation
07506C DCN6727 47
Status Description
Nozzle Pressure The pressure difference upstream and downstream
of the optics assembly. Should be 100% - a 10%
drop in nozzle pressure indicates a nozzle clog.
Separator Temp Temperature of the Separator in degrees Celsius. A
normal Separator temperature is 7°C.
Cabinet Temp Temperature inside the Model 651 cabinet.
Laser Current The operating current of the laser in mA.
Photodetector Indicates photodetector voltage in mV.
Analog Input Displays the voltage of the analog input.
Flow Constant Represented in particles/cm3. Compensates for any
variations in orifice diameter.
