Description

The pressure difference upstream and downstream of the optics assembly. Should be 100% - a 10% drop in nozzle pressure indicates a nozzle clog.

Temperature of the Separator in degrees Celsius. A normal Separator temperature is 7°C.

Temperature inside the Model 651 cabinet. The operating current of the laser in mA. Indicates photodetector voltage in mV. Displays the voltage of the analog input.

Represented in particles/cm3. Compensates for any variations in orifice diameter.
