Page 29: Liquid Level
Liquid Level Full is indicated if adequate butanol is present in the liquid reservoir as detected by the internal reservoir liquid level sensor. If the liquid level is low, Not Full is indicated. Laser Current Laser power is monitored by an internal detector in the laser diode package, and displayed. - Page 30 CPC for use whenever the CPC is shipped, including when it is returned to TSI for service. Always seal off the sampling inlet with a cap or tape to prevent debris from entering the instrument and drain and dry the CPC before shipping. Model 3750 Condensation Particle Counter...
- Page 31 C a u t i o n While the flow is on, do NOT tip the CPC more than 5° to any direction. It is recommended to turn off the CPC and disconnect the butanol fill bottle before the CPC is being moved or tilted for longer than a few seconds to prevent flooding of the sensor.

Page 34: Flow System
The CPC relies on an external (user supplied) high-vacuum pump to maintain constant flows through a critical orifice inside the CPC. The flow rate through the sensor is always 1.0 L/min. More information on instrument flow is provided below. Model 3750 Condensation Particle Counter... - Page 35 Critical Flow To achieve the flow through the sensor, an orifice is used, operated at the critical pressure ratio to provide a critical flow. Critical flow is very stable and is a constant volumetric flow, assuring accurate concentration measurements despite varied inlet pressure. The critical pressure ratio is found by dividing the absolute pressure downstream of the orifice P , by the absolute pressure upstream of the...
