OPERATION
Page 5-2 SmartTach Operating Manual
General Information
Operation of the SmartTach is straightforward for most applications. When
power is first applied to the unit, the default operating mode is Measure
Mode. This operating mode instructs the SmartTach to function in its
normal mode of measuring speed. The current configuration parameter
settings (most recently set and retained in memory) are used for all
functions.
Measure Mode
The SmartTach Measure Mode has several functions and capabilities other
than simply displaying Speed.
Display Maximum/Minimum Attained Values
This feature will display the maximum or minimum attained speed values
since the last reset. This is independent of the Range Outputs. When this
feature is active, the measurement units will be replaced with max and
min.
This feature is useful to observe the maximum/minimum values attained
during transients (which would be difficult to see real-time visually on the
display). This feature can also be used to see the value(s) which triggered
any Range Outputs that may have been set.
After viewing the maximum/minimum values, the unit can be returned to
normal Measure Mode with or without resetting the maximum/minimum
values. If the values are reset, the new minimum/maximum values begin
at the current measured speed.
After power is first applied, or connection/disconnection of the input
cables, the maximum/minimum values may be corrupted due to
intermittent noise while making connections. Therefore, if this function is to
be used, the maximum/minimum values should be reset prior to initial use.
