4.2.2. Input / Digital Input Setup (Tachometer Mode)

Input Setup allows the user to configure a set of global constants that affect how

the tachometer reacts to incoming signals. In tachometer mode, the instrument

measures and reacts to external events in terms of frequency or rate. All math and

normalization operations as well as alarm setpoints, hysteresis and scaling are

performed as frequency, speed or rate. When in Tachometer mode, both Period

and Direction detection are active. In counter mode, only direction detection

applies. Direction will be discussed in more detail in subsequent sections.

In order to access special menus for Counter, Tachometer, Direction,

etc, the mode must first be selected and active. Select the mode (as

illustrated below), exit to the Main screen and save the change. Re-entry

into the menus will now provide the mode-specific constants. See

in section 4.2.3 for greater detail.
