TT-830 Bench Scale Service Manual
Introduction
Front Panel Keys and Functions
This manual covers the information you need to configure and service your
TT-830 bench scale.
Major sections of this manual are headed by titles in a black bar like Intro-
duction above. Subheadings appear in the left column. Instructions and text
appear on the right side of the page. Occasionally notes, tips, and special
instructions appear in the left column.
The front panel is shown in Figure 1.
About This Manual
Plug the TT-830 into an easily
accessible grounded outlet
only. Never use the unit without
an appropriate earthground
connection. 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 function differently at different times so their labels 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 to clear values from the display.
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. Press any key to power up the scale.
The numeric keypad is for entering numbers.
Soft keys are so-called because their function is not fixed. Function can
change as the mode of operation changes 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.
Soft Keys

TT-830 Bench Scale Service Manual
There are three levels of TT-830 setup you can access through the front
panel:
User level
The first level is the User level. These are the most commonly
changed values and parameters that you will use in the course of
operating the TT-830.
Configuration level
The second level is the Configuration level. These items deal with
some of the basic functions of the TT-830 and do not need to be
accessed very often.
Calibration level
The third level is the Calibration level. This section will need to be
accessed only when the scale is being calibrated, or if you change
scale capacity or division size.
A different password is needed to access each level. Once you access the
level you want, the display presents a series of soft key choices. By pressing
the appropriate soft key and following text prompts on the display, you can
set up your TT-830 to suit your needs.
Following are the instructions you need to access the setup of the TT-830.

SCALE
Any value for display update
rate greater than 2 will be
considered as the maximum
update rate or 99.
If you press the SCALE soft key, follow these instructions (see note at left):
1. The display will show the current
display rate (.1, .25, .5, 1, 2, 99).
Accept this by pressing the
ENTER key or key in a new
value and press the ENTER
key. . . The display shows the zero range
value. If a non-valid number is keyed
in the value will default to 99.
2. Repeat step one for zero range
(0-100% allowed). . . This is the percentage of capacity
that you are allowed to zero using
the ZERO key.
3. Repeat step one for print return to
zero (0-100% of cap. allowed). . . If you press the PRINT key, the
weight must fall below this percent-
age of scale capacity before another
print operation will be allowed.
4. Repeat step one for accumulate
return to zero (0-100% allowed). . . If you perform an accumulation, the
weight must fall below this percent-
age of scale capacity before another
accumulation operation will be
allowed.
If you press the UNITS key, follow these instructions:
1. The display asks if you want to
enable the LB unit of measure
and shows you the current state
(ON or OFF). If the condition is
as you want it, simply press the
ENTER key. If you want to
change the condition, press the
YES or NO soft key, then the
ENTER key to move to the next
unit of measure. . . The kilogram unit of measure is the
next one shown.
2. Repeat step 1 for kilograms,
grams, ounces, pounds &
ounces, and custom units 1 and
2. The display asks for the
conversion factor for each
custom unit. Key in a value and
press ENTER. . . The display returns to the
CONFIGURE-MENU1display.
If you press the SETPT soft key the display asks you SHOW SETPOINTS?
What this means is, if you say yes, the display will show when setpoints turn
on and off by lighting small dots in the upper right corner. Press the YES soft
key if you want to see these dots, and press NO if you do not.
Custom unit names must be
defined by SimPoser software
program.
The custom conversion factor
is the number to be multipied
by the weight (in calibration
units) to get the desired
custom unit. Example: 1 lb = 5
inches of a certain steel rod.
Custom unit is inches. Calibra-
tion unit is lb. Conversion factor
is 5. With six lbs of weight on
the scale, 30 inches would be
displayed.
(Six lbs x 5 = 30 inches of
steel)
Setpoint operations must be
defined by the TT-830
SimPoser software program.
UNITS
By default, when the PRINT
key is pressed, a print opera-
tion and an accumulation take
place. If you do not want the
accumulation to occur, a WT-
BASIC program assigning only
the DO PRINT command to the
PRINT key needs to be down-
loaded to the TT-830. A WT-
BASIC program can also
define an ACCUM. soft key
and assign accumulation to
that key only.
SETPT
The display will first ask for a
scale number if Multiscale is
enabled.

TT-830 Bench Scale Service Manual
BASIC Control -Control of the serial port is through the BASIC program
executing in the TT-830.
Keyboard - Control of the serial port is through an attached keyboard.
Disabled - The serial port is not in use for this configuration.
Split - Port 2 is split between two devices; keyboard and BASIC
control.
Dual - Port 2 allows detecting for data on two input lines for BASIC
control.
7. Press ENTER to accept the
EOM character or key in a new
number from 0-256 and press
ENTER. . . The display returns to the
CONFIGURE-MENU1display.
This completes the instructions for all the parameters of Menu 1.
Press the MENU2 soft key to access the following soft key group (See note
at left):
• MOTION Use this key to set the motion detection window size in
divisions and the time window in seconds.
For example: If you set divisions to 3 and seconds to 1, if
the weight value does not change more than 3 divisions
in one second, the scale or weight is considered stable.
• AZT Use this key to enable AZT. If you enable AZT you can
set the division size and seconds. The division size you
pick defines a range above and below zero. When scale
weight is inside this range for the number of seconds you
picked, ½ of the weight will be zeroed. The indicator will
repeat removing ½ the weight every X seconds. X being
the number of seconds you have picked.
• FILTER Use this key to set up the Harmonizer filtering. A full
explanation is given below. See Appendix 2 for tips on
using Harmonizer.
For a remote analog base the A-D weight conversion
happens 60 times per second in the TT-830. AVG is the
number of conversions you want to average. For ex-
ample, if you pick 30, the unit will average the weight
values from the last 30 conversions or ½ second and
uses that value for displayed data.
The next choice you have is for turning the Harmonizer
filtering on or off. If you turn the Harmonizer filtering on
you need to set the Harmonizer Constant. Typical values
are between 0-10. Set the number low for small vibration
problems and higher for more dampening effect.
The purpose of the Harmonizer Threshold is so the
indicator will respond quickly to large weight changes.
Harmonizer Threshold is the amount of weight change, in
calibration units, beyond which the Harmonizer will be
temporarily disabled. For example, if you set this to 10
EOM ASCII code #13 is
carriage return.
In the SimPoser software the
Harmonizer constant choices
are 0 through 10. This setting
is to be made in the "real
world" on a working system so
there are more levels available
from the front panel.
CONFIGURE-MENU 2 Level
For all the parameters in the
this menu level the display will
ask for a scale number if
Multiscale is enabled.

18 TT-830 Bench Scale Service Manual
lbs, a weight change over 10 pounds occuring during the
sample time (½ sec. in our example) will disable the
Harmonizer until the weight change during the sample
time drops below 10 lbs.
• TMOUT Use this key to set Zero Timeout, Tare Timeout, Print
Timeout and Accumulate Timeout. This is the amount of
time the TT-830 will wait for motion to cease and perform
the function after the key is pressed.
For example, if Zero Timeout is set to 3 seconds, when
the ZERO key is pressed the unit will zero the scale if
there is no motion. If there is motion and motion ceases
within 3 seconds the unit will zero the scale. If motion
doesn't cease the key press is ignored.
• EXIT Press this key to go back to the previous soft key set.
Following are detailed instructions for setting these parameters.
If you press the MOT'N soft key, follow these instructions:
1. The current value for the motion
window size, in divisions, is
shown. Press ENTER to accept
this value or key in a new value
and press ENTER. . . The current time window in seconds
is displayed.
2. Press ENTER to accept this time
period or key in a new value and
press ENTER. . . The display returns to the
