ABSTRACT:
A method and apparatus for converting a single function, i.e., hydrocarbon detection, well logging tool to a dual function tool, i.e., the detection of naturally occurring gamma rays, by making the amplitude reference pulses necessary for single function operation related in rate to the second function. A minimum constant rate of amplitude reference pulses are provided to ensure the operability of the single function tool in the absence of the second function and an adjustment is thereafter made to remove the effects of this minimum rate of reference pulses.
