13. 5 8 1 Event Pacing 5 12 Suction head is the vertical distance between the surface of the liquid source and the sampler s pump At each sample event the sampler determines the suction head automatically In extended programming you can manually enter the suction head if you want Select ENTER HEAD only when the head remains stable and you can measure it accurately Rinses and retries are extended programming features You can program the sampler to rinse the suction line automatically During a line rinse cycle the sampler draws liquid through the line to the liquid detector As soon as it detects liquid the sampler reverses the pump to purge the line The sampling retries feature lets you set the number of times from 0 to 3 that the sampler tries to detect liquid in the line before skipping the sample Sample pacing is the rate at which the sampler takes samples Depending on the type of pacing you select the rate is controlled by the sampler s internal clock or by inputs received from con nected instruments Standard programming provides time pacing and flow pacing which are described in Section 4 Extended programming pro vides additional pacing types so its pacing screen see example in margin has four items listed instead of two Uniform time pacing is identical to time pacing in standard programming Flow paced is the same for both types of pro gramming Event paced and nonuniform time
