PARAMETER MENU
The three user inputs are individually programmable to perform specific
meter control functions. While in the Display Mode or Program Mode, the
function is executed the instant the user input transitions to the active state.
The front panel function keys are also individually programmable to perform
specific meter control functions. While in the Display Mode, the primary
function is executed the instant the key is pressed. Holding the function key for
three seconds executes a secondary function. It is possible to program a
secondary function without a primary function.
In most cases, if more than one user input and/or function key is programmed
for the same function, the maintained (level trigger) actions will be performed
while at least one of those user inputs or function keys are activated. The
momentary (edge trigger) actions will be performed every time any of those
user inputs or function keys transition to the active state.
Note:
In the following explanations, not all selections are available for both
user inputs and front panel function keys. Alternating displays are shown
with each selection. Those selections showing both displays are available for
both. If a display is not shown, it is not available for that selection.
will represent all three user inputs.
will represent all five function keys.
NO FUNCTION
No function is performed if activated. This is the factory setting for all user
inputs and function keys. No function can be selected without affecting basic
start-up.
PROGRAMMING MODE LOCK-OUT
Programming Mode is locked-out, as long as activated
(maintained action). A security code can be configured to
allow programming access during lock-out.
ZERO (TARE) DISPLAY
The Zero (Tare) Display provides a way to zero the Input Display value at
various input levels, causing future Display readings to be offset. This function
is useful in weighing applications where the container or material on the scale
should not be included in the next measurement value. When activated
(momentary action),
flashes and the Display is set to zero. At the same
time, the Display value (that was on the display before the Zero Display) is
subtracted from the Display Offset Value and is automatically stored as the new
Display Offset Value (
). If another Zero (tare) Display is performed, the
display will again change to zero and the Display reading will shift accordingly.
RELATIVE/ABSOLUTE DISPLAY
This function will switch the Input Display between Relative and Absolute.
The Relative is a net value that includes the Display Offset Value. The Input
Display will normally show the Relative unless switched by this function.
Regardless of the display selected, all meter functions continue to operate based
on relative values. The Absolute is a gross value (based on Module 1
DSP and
INP entries) without the Display Offset Value. The Absolute display is selected
as long as the user input is activated (maintained action) or at the transition of
the function key (momentary action). When the user input is released, or the
function key is pressed again, the input display switches back to Relative
display.
(absolute) or
(relative) is momentarily displayed at transition
to indicate which display is active.
HOLD DISPLAY
The shown display is held but all other meter functions
continue as long as activated (maintained action).
HOLD ALL FUNCTIONS
The meter disables processing the input, holds all display
contents, and locks the state of all outputs as long as activated
(maintained action). The serial port continues data transfer.
SYNCHRONIZE METER READING
The meter suspends all functions as long as activated
(maintained action). When the user input is released, the
meter synchronizes the restart of the A/D with other
processes or timing events.
STORE BATCH READING IN TOTALIZER
The Input Display value is one time added (batched) to the Totalizer at
transition to activate (momentary action). The Totalizer retains a running sum of
each batch operation until the Totalizer is reset. When this function is selected,
the normal operation of the Totalizer is overridden.
SELECT TOTALIZER DISPLAY
The Totalizer display is selected as long as activated
(maintained action). When the user input is released, the
Input Display is returned. The
DSP key overrides the active
user input. The Totalizer continues to function including
associated outputs independent of being displayed.
