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
(a digital input located on the signal input connector), and up to eight additional digital inputs to access
most of the menus or to activate certain functions immediately (e.g. reset max & min, hold relay states,
etc.). This allows the meter to be greatly customized for use in specialized applications.
Up to eight digital outputs can be assigned to a number of actions and functions executed by the meter
(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.
