Digital display plug‐in module for the Victoreen model 555 integral and rate exposuremeter
Jeffrey L. Silberberg · Medical Physics · 1976
A digital display plug-in for use with the Victoreen 555 exposuremeter is described. The device is a readout subsystem for displaying numerical and dimensional information in a clear, legible form, with both probe and range scale factors accounted for in the display itself. In addition to facilitating data gathering with the 555, the device circumvents nonlinearity in the analog meter movement. Minor modifications required of the 555 mainframe are described.
