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-MENU1 display.
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.
