11 Mode 3: Falling Edge, Prescaler = 4 In this mode, the signal input is measured at every 4th falling edge. This mode is especially useful when the signal input frequency is beyond the native pulse-per-minute range of the DTM8000. Because unit will automatically compensates for the prescaler, there is no need to factor in the prescaler value when [...]

12 Parameter 25  Signal Input 1 (S1) Decimal Point (DP) Position This selects the format of the display with respect to the decimal points position. This parameter does not effect the value entry for other parameters. For example, it the user desires to display 10.00 at an input of 300RPM, then parameter 20 would be set to 1000, parameter 21 [...]
