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.
