Purpose: To select the type of measurement you would like the SmartTach to
perform. This is the main configuration parameter for the SmartTach
and should be the first parameter set when setting up a new
configuration. Changing this parameter will change the state of
other parameters in the

Measurement
EngSp Used to measure the number of revolutions over time.
Generally engine RPM, but can be used to measure any
rotating components if a signal is available.
VehSp Used to measure speed when the speed signal is in
“pulses/distance” as in 300pulses/meter.
DynSp Used to measure speed when the signal is in
“pulses/revolution” as in 1200 pulses/revolution.
Freq Used to measure the Frequency of the input signal.
Per Used to measure the Period of the input signal.
PW Used to measure the Pulsewidth of the input signal.
Duty% Used to measure the Duty Cycle of the input signal.
Vaux Used to monitor the auxillary input voltage. In this mode
the Aux. input is treated as a speed measurement. The
analog output and range outputs are a function of the
Aux. input voltage.
