Page 5: Section 1-Overview
CD-20 Sample Probe Controller Section 1—Overview The CD-20 Sample Probe Controller is engineered for use with the True-Cut C-Series sample probe. It provides both pulse input (flow proportional) and repeat (time proportional) control of the sample probe. When a “start” pulse is received, the probe is rotated to capture and discharge a 1.5-ml isokinetic sample. When installed in a horizontal line, the probe is stopped in the closed position, while on a vertical line the probe is stopped in the open position. -

CD-20 Sample Probe Controller Repeat Mode (Time-Proportional) Check-Out The repeat time potentiometer (Figure 2.3), which determines the rate of sampling when the controller is connected to a probe, is typically set at the factory at 15 seconds. However, it can be adjusted over a range of 3 seconds to 3 minutes. -
