Appendix A: Sample Size Calibration

Use the following graph to see how sample size changes with head height. The Sample

Size controls on the control panel are calibrated at a height of 4 feet. Increasing the head

height decreases the sample size by a predictable amount. To determine the appropriate

Sample Size setting for a desired volume; find the sample size on the horizontal axis, follow

straight up to the line corresponding to your head height, then look across to the vertical

axis and read the setting for the Size control on the control panel.
