The input pulses from the transducer are counted and then multiplied by "M" (input count multiplier). In order to have a steady
display, the display is updated every .0167 seconds x "S" (divide by count time) for the DM4004. The multiplier "M" is a phase lock
loop, while the divide by, "S", is a simple timer set via binary switches. Thus, we have field programmable scaling. The unit provides
+5 VDC for the transducer.
