2.6 Scale Base Setup
In this section, you will enter the menu for the first time. Do not worry if you are unfamiliar with the function of the
buttons on the panel, the display provides the necessary coaching as you go along. Before the Indicator can be used,
the parameters for the scale base being used with the Indicator must be set first in order to calibrate and perform any
functions.
The indicator itself has three basic menus; each is selected by front panel buttons marked Mode, Units and Setup.
Mode Button
The Mode button, when pressed, permits the selection of 5 weighing modes which are: weigh, percent, count, animal
weighing and checkweigh. These modes are controlled by an ON or OFF selection made in the Setup menu under the
submenu Mode as displayed.
Units Button
The Units button, when pressed, allows the Indicator to display values in a selected measuring unit of either grams,
kilograms, pounds, custom, parts counting or percent.
Setup Button
The Setup button, when pressed, allows entry into 14 submenus which allows you to set the Indicator for specific
operating parameters. Each of the 14 submenus contain settings which are user selectable . The table which follows
the scale base setup illustrates the various submenus and the functions which are selectable. The items shown on
the menu, which are bolded, are the factory default settings. In other words, if you did not enter the Setup menu, the
Indicator would function in the basic manner shown by the various settings which are bolded. The setup submenus
shown are arranged in the order as displayed in the Indicator .
Scale Menu
The Scale menu is the first menu presented when the Setup button is pressed. This menu allows you to set the proper
parameters of the scale base such as zero setting, calibration unit, graduations, full scale capacity and to lock all
settings. The definitions are as follows:
• Zero - The percentage of capacity which the user is allowed to zero the scale base and can be set
to 2%,18% or 100%. If the weight on the scale base is greater than the selected percentage, the >0< button will not respond.
• Cal Unit - kg, lb are used to set the scale base capacity and calibrate the unit. If the display units are
the same as the Cal unit, then weight displayed on the Indicator will be a multiple of the
Grad setting.
• Grad - The display increment of the scale base can be set to .0005, .001, .005, .01, .02, .05, .1,
.2, .5, 1, 2, 5, 10, 20, 50, 100. The weight displayed on the scale will always be a m ultiple
of the Grad (graduation).
• Full Sc - This represents full scale base capacity and the user may enter 7 digits. Number may be
entered using the arrow or numeric buttons. This number must be betw een 1 and 199999.

The stability range specifies the weighing results and must be within a preset tolerance limit for a certain time to turn
the stability indicator ON. When a displa yed weight changes be yond the allo wab le range, the stability indicator turns
OFF, indicating an unstable condition. F actory default setting is sho wn in bold type.
.5 d Smallest range: stability indicator is ON only
when displayed weight is stable within .5 divisions.
1 d Normal range.
2 d Medium range.
5 d Largest range, stability indicator is ON even though displayed weight
changes slightly.
When the RS232 communication parameters are configured to print stable data only, the stability range also governs
data output. Displayed data will only be output if it is within the selected stability range.
Auto-0 (Auto-Zero)
Auto-0 minimizes the eff ects of temperature changes and shift on the zero reading. The Indicator maintains the zero
display until the threshold is exceeded. Factory default setting is shown in bold type.
OFFTurns Auto-Zero OFF.
.5 d Sets threshold to .5 divisions.
1 d Sets threshold to 1 division.
3 d Sets threshold to 3 divisions.
Filter
Filter compensates for vibration or excessive air currents. Default settings is shown in bold type.
-0- reduced stability, fastest stabilization time
-1- normal stability , normal stabilization time
-2- more stability, slow stabilization time.
-3- maximum stability, slowest stabilization time.
Sleep On/Off
When set ON, power will be removed from only the displa y in 5 min utes after last weighing. When set OFF, power
remains on all of the time to the Indicator circuitry and display. To turn power ON, press Enter.

4. OPERATING YOUR INDICATOR
4.1 Calibration
Model CD-31 and CD-33 Indicators offer a choice of four calibration methods: Span, User, Linearity, and CalT estTM.
•
Span
- Span calibration ensures that the Indicator reads correctly within specifications using a
weight value of 100% of capacity.
• User
• Linearity
• Cal Test
•
- User calibration is a method where the Indicator can be calibrated using a mass between 10%
and 100% of capacity and by entering that numeric value into the Indicator .
- Linearity calibration minimizes deviation between actual and displayed weights within the
Indicator's weighing range. Three weight values are used: zero , a weight value at or near
midpoint and full scale.
- User may enter calibration test point by entering that numeric v alue into the Indicator .. The
difference in weight is indicated.
Lock
- Can be set on or off. When set on, Span, User and Linearity are lock ed out and cannot be
used.
Calibration Menu Protection
NOTES:
• Calibration may be locked out to prevent unauthorized personnel from changing calibration. If calibration has been
locked out, you can only access Cal Test.
• To lock out calibration menu, after calibration, refer to the section titled paragraph 3.12, Menu Lock-Out Protection.
Calibration Masses
Before beginning calibration, make sure masses are available. If you begin calibration and realize calibration masses
are not availab le, e xit the menu. The Indicator will retain previously stored calibration data. Calibration should be

4.2 Weighing
The Indicator is shipped with kilograms only enabled. When the Indicator is to be used with other Type Approved/Legal
for Trade units of measure, the desired unit must be enabled. Ref er to paragraph 3.9 to enable other measuring units.
The Indicator is equipped with a G/N/T button which allows the viewing of gross weight, net weight and tare weight. A
T are button allo ws taring the weight of container , and a separate >0< zero button, z ero's the Indicator display reading.
Weighing Procedure
• Press >0< to rezero the display.
• Press Units button to select measuring unit. If an
error code appears, refer to paragraph 5.2.
• Press or button for desired measuring unit.
• Press Enter button, Indicator is now ready for weigh-
ing.
• Press >0< to rezero the display.
• Place the object(s) or material to be weighed on the
pan. Example illustrates a 2kg weight.
• Wait for the Stable indicator to appear bef ore readin g the weight.
4.2.1 Manual Taring
When weighing material or objects that must be held in a container , manual taring stores the container weight in the
Indicator’s memory, separate from the weight of the material in the container.
When a container has been placed on the pan and tared, its weight is stored in memory . Adding material to the
container is shown as NET weight. The gross weight is a combination of the tared weight and the material. The G/N/T
button allows switching between GR OSS, NET and TARE weights.
Procedure
• Press >0< button with no load on the pan to set the
Indicator reading to zero.
• Place an empty container on the pan. Its B/G weight
is displayed.
• Press the Tare button, display blinks until stable
weight readings are received, then indicates NET
WEIGH 0.00. The container’ s w eight is stored in
memory.
• Add material to the container. As material is added,
its net weight is displayed.
• Removing the container and material from the pan will
cause the Indicator to display the container’s weight
as a negative number . The tared w eight will remain in
memory until the Tare b utton is pressed again or the
Indicator is turned off.
• Pressing Tare clears tare from memory .

CD Indicators
4.2.2 Preset Taring
Preset taring is used to enter a tared weight via the numerical keypad. If a container's weight is known, the Indicator
may be preset using the numerical keypad to enter the w eight. When using this feature, a time constraint of 4 seconds
is imposed to start entering data, otherwise the Indicator defaults back to a weighing mode.
Procedure
• Press >0< button with no load on the pan to set the
Indicator reading to zero.
• Press the number 0 on the numeric keypad, the
display indicates P>TARE 00000.00 kg with the
second digit blinking. Using the keypad, enter the
desired tare weight. Remember the weight is either in
pounds or kilograms whatever w as set pre viously. If
the number is not entered, the display indicates an
ERROR CODE 2.1; this is normal. The Indicator
returns to a weighing mode automatically . If entered
correctly , the tare w eight is stored in the Indicator.
• Press Enter button, Indicator is now ready for weigh-
ing. The displa y indicates NET WEIGH and the
amount of tare weight as a negative number . The
illustration indicates a 2kg weight. The next two steps
are for an empty container and a full container .
T are weight
Net weigh - container tared
Container with material
• Place the empty container on the pan. If the weight
entered was correct, the display indicates 0.00 kg.
Material may be added to the container, the displa y
indicates the net weight.
• Place a container with material on the pan. The
display indicates NET WEIGH of the material only. The
weight of the container which was entered is automatically subtracted. Illustration indicates a 10kg of
material in a 2kg container.
• Each press of the G/N/T button will advance the
display to NET WEIGH (net w eight), B/G WEIGH
(gross weight) which includes the container's weight,
and PT WEIGH (preset tare weight of the container).
Th e tare weight remains in memory until the Tare b utton is pressed or the Indicator is unpluged from the
power source.
• Pressing Tare clears tare from memory .
