Title and Subtitle: Calibration of an electronic counter and pulse height analyzer for plotting erythrocyte volume spectra

Report Date: March 1963

Authors: McKenzie JM, Fowler PR, Lyne PJ

Abstract: A simple technique is presented for calibrating an electronic system used in the plotting of erythrocyte volume spectra. The calibration factors, once obtained, apparently remain applicable for some time. Precise estimates of calibration factors appear to be limited by errors in measuring hematocrit and/or mean channel. For consistent determination of the latter, the selection of a sufficiently low aperture current appears to be of importance.
