The ORTEC Model 449 Log/Lin Rate Meter provides two modes of operation: linear and logarithmic. The linear mode has 11 full-scale ranges from 10 to 106 counts/sec in 1-3-10 steps. The 5-decade log mode covers the range from 10 to 106 counts/sec in a single span. These selections permit logical operation of the instrument when measuring low, medium, or high steady pulse rates or when monitoring rates that vary through a wide range.
