A Transistorized Logarithmic Counter Ratemeter HASL Type TR-1

Abstract: A four decade log count ratemeter based on a three diode pump section is described. The design equations for this system are included. The unit is contained in a chassis 3 1/2" high by 9 1/2" wide by 6" deep. All circuits are constructed on etched circuit boards to facilitate testing, construction, and servicing.
