Programmable Function Keys User Menu (
user
)
The
User
menu allows the user to assign the front panel function keys F1, F2, and F3, the digital input F4 (located on
the input signal connector), and four digital inputs (located on the digital I/O connector) to access most of the menus
or to activate certain functions immediately (e.g. reset max & min, hold relay states, etc.). This allows the scanner to
be greatly customized for use in specialized applications.
The four digital outputs can be assigned to a number of actions and functions executed by the scanner (i.e. alarms,
relay acknowledgement, reset max, min, or max & min, tare, and reset tare). The digital outputs can be used to
trigger external alarms or lights to indicate these specific events.
