TT-830 Front Panel

6TT-830 Bench Scale User’s Manual

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 particu-

lar needs. The screen you see will depend on what weighing application you

are performing.

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.

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

displayedchoice.

Press and hold the ON/OFF key for five seconds to turn the

unit off.

The numeric keypad is for entering numbers.

TT-830 Bench Scale User’s Manual

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 SimPoserTM

software available from Weigh-Tronix and download it to the scale.

TT-830 Bench Scale User’s Manual

Due to the unlimited variety of applications available for the TT-830, it is not

practical to describe all the possible specialized operations in this manual.

Each application program will be unique.

Specialized operations will offer you soft key choices specific to the applica-

tion and will guide you with messages on the display.

The time may come when you are asked by a service technician for informa-

tion about your software program. There is a series of key strokes which will

bring that information to the screen. Below are the instructions:

1. Press and hold the ESCAPE key until the TT-830 beeps.

2. Within five seconds, key in the number 111 and press ENTER.
