Main Display
The main display is a 240 x 64 dot matrix LCD display with cold cathode
fluorescent backlight. It can display graphics, words and numbers. This
flexibility allows graphics and alphanumeric characters to be displayed at the
same time. There are 33 displays available on the TT-830. See the Service
Manual for all the examples. Your system will be configured for your particular needs. The screen you see will depend on what weighing application you
are performing.
Front Panel Keys
Hard Keys
The keys on the front panel of the TT-830 are of two types, hard keys and
soft keys. Hard keys are labeled directly and soft key labels appear on the
display. Soft keys (F1-F5) function differently at different times and their
labels appear on the main display and they change as needed.
Below are brief descriptions for each of the hard key functions:
Repeatedly press the SELECT key to scroll through the
available weight reading displays. (Examples - gross, net,
tare, minimum, maximum, etc.)
Press the UNITS key to scroll through the available units of
measure.
Press the PRINT key to send data to a connected printer.
Press the TARE key to enter a tare weight, then press
SELECT to see the net display mode.
Press the ZERO key to establish a zero reference. A
center-of-zero icon will be displayed. During motion an M
will appear below the center-of-zero icon.
To increase the contrast of the
display, press and hold the
CLEAR and 9 keys until the
desired contrast is reached. To
decrease contrast, press and
hold the CLEAR and 3 keys.

Press the ESCAPE key to back out of menus or cancel a
numeric entry without accepting the value.
Press the CLEAR key to clear values from the display.
See note at left.
Press the ENTER key to enter a keyed in value or accept a
displayed choice.
Press and hold the ON/OFF key for five seconds to turn the
unit off.
The numeric keypad is for entering numbers.

Soft Keys
Installing the TT-830
Soft keys are so-called because their function is not fixed. Function can
change as mode of operations change or as the program for your particular
setup changes.
Their are five soft keys located directly below the display. If the keys are
needed during any operation, a label for each active key appears in the
display directly above. There are only five key labels available at one time
but this does not limit the potential usefulness of these keys. Programs can
be created to enable one key to access another level of operation with five
more key names and functions.
After unpacking the scale, place it on a level, stable surface. Plug it into an
appropriate power source. The outlet must be properly grounded and readily
accessible.
A new unit will power up ready to use. This scale is fully programmable. If
you have a custom program resident in your unit, it will power up with that
program active and ready to use.
Since custom programming is possible with this scale, the following pages
only cover basic weighing procedures available when you receive a factory
fresh scale.
To customize your unit you must write a program using the 830 SimPoser
software available from Weigh-Tronix and download it to the scale.
