3-10 Model 3022A Condensation Particle Counter
Liquid Drain
Liquid Drain is a quick-disconnect, shut-off connection. Use it with
the liquid drain bottle placed below the base of the CPC to allow
gravity to drain the instrument.
Operating Specifications and Precautions
This section contains operating specifications and precautions. Also
refer to the Safety section at the front of this manual and
Appendix B, “Specifications.”
Ambient Temperature
Do not operate the CPC in ambient temperatures outside the
control range of 10°C to 34°C. If you run the CPC outside of this
range, its data may be invalid.
Inlet Pressure
The built-in pump and flow sensor cannot control the flow when
the pressure at the aerosol inlet, the makeup air inlet, or the pump
exhaust is too high or too low. The remedy depends on the
sampling mode: high flow or low flow.
First, view the flow display by activating the secondary function
“Status;” then follow the directions given for either the high-flow or
low-flow mode. As a further aid, monitor the pump-control voltage
of the microprocessor using the Analog Output jack on the back
panel (see Chapter 4).
High Flow Mode
In the high-flow mode, connect the Pump Exhaust outlet to the
same pressure conditions that apply to the inlet so that the
pressure drop across the CPC is close to normal conditions.
If you are sampling from a closed system, add a pressure-equalizing
line from the pump exhaust to the system downstream of the
