INTRODUCTION
The CDT series offers a range of an accurate, fast and versatile counting scales that
can use one additional external platform (Remote scale) for weighing or counting of
heavier items.
These counting scales have the ability to use many stored information (PLU).
The scale can be operated using either pounds only, kilograms only or can be
switched between pounds and kilograms.
All have stainless steel weighing platform on a Steel base assembly.
All the keypads are sealed, colour coded membrane switches and the displays are
large easy to read liquid crystal type displays (LCD). The LCD’s are supplied with a
backlight.
All units include automatic zero tracking, audible alarm for pre-set weights,
automatic tare, pre-set tare and an accumulation facility that allows the count to be
stored and recalled as accumulated total.
The scales have an bi-directional RS-232 interface for communicating with a PC or
printer. An optional USB interface is available.

3.0 INSTALLATION
3.1 LOCATING THE SCALES
The scales should not be placed in a location that will reduce the accuracy.
Avoid extremes of temperature. Do not place in direct sunlight or near air
conditioning vents.
Avoid unsuitable tables. The table or floor must be rigid and not vibrate.
Avoid unstable power sources. Do not use near large users of electricity such
as welding equipment or large motors.
Do not place near vibrating machinery.
Avoid high humidity that might cause condensation. Avoid direct contact with
water. Do not spray or immerse the scales in water.
Avoid air movement such as from fans or opening doors. Do not place near open
windows or air- conditioning vents.
Keep the scales clean. Do not stack material on the scales when they are not
in use.
3.2 SETTING UP THE SCALES
SETTING UP THE LOCAL SCALE
The CDT Series comes with a stainless steel platform packed separately.
Place the platform in the locating holes on the top cover.
Do not press with excessive force as this could damage the load cell inside.
Level the scale by adjusting the four feet. The scale should be adjusted such
that the bubble in the spirit level is in the centre of the level and the
scale is supported by all four feet.
Connect power adapter to the socket on the right underside.
The power button is located on front left of the scale.
The scale will show the model number in the “Weight” display window (CDT 8,
where 8 denotes the maximum capacity of the scale in Kg) and the current
software revision number in the “Unit Weight” display window.
Next a self-test is followed. At the end of the self-test, it will display
“zero weight and zero values in all three displays. If the weight display
shows a value it was not possible to set a new zero during power on.
SETTING UP THE REMOTE SCALE
The CDT Series can be connected to any size of load cell type weighing base
via the Remote scale port on the right side of the scale case. Ensure you have
the correct base for the scale as each is matched for calibration.
Place the remote scale platform in the position where it is to be used. Level
the scale by adjusting the four feet. If fitted with a spirit level then it
should be adjusted such that the bubble is in the centre.
Press [Local/Rem] to select the local scale or the remote base for
configuration and operation.
REMOTE SCALE CONNECTION
The cable for the load cell goes to a 9 pin D-subminiature plug connector with the following connections:
Pin numbers Pins 1,2 Pins 4,5 Pin 6 Pin 7
Connection + Excitation (+5 V) – Excitation (0 V)
+ Signal – Signal
(The sense wires connections of a six wire load cell are not used and should be connected to the respective Excitation pins).
3.3 REMOTE SCALE SET UP
The remote scale should set for a realistic resolution with respect to the
input provided by the load cell/s. See Section 14 for details of configuring
the remote scale.
If a single 2 mV / V load cell is fitted and more than 60% of the load cell is
used for full capacity then the high output of >6 mV span makes it possible to
set a high resolution.
If this criterion is met then the remote scale can be set to a high resolution
with a maximum of 1:30,000, i.e. 300 kg x 0.01 kg.
Where more than one load cell is fitted or the total load cell capacity is not
utilised then a reduced resolution should be selected in the remote scale
technical set up. For example, if a system uses four 2 mV / V 1000 kg load
cells for a scale of 1000 kg capacity then the span output at full scale will
be only 2.5 mV.
In this situation the resolution should be reduced to give a good number of
ADC counts per displayed division. ie. Set to 1:5000 or 1000 kg x 0.2 kg.
Setting a high resolution without providing a good input to the remote scale
ADC will not give better accuracy and may make the scale difficult to meet
performance specification.
4.0 KEY DESCRIPTIONS
[0-9, ·] These keys are used to manually enter a value for tare weights, unit
weight and sample size. A secondary function is to enter alpha-numeric
characters for PLU descriptions etc.
[CE] Pressing this key clears the unit weight or an erroneous entry. It also
clears the memory accumulation when the total is displayed.
[M+] This key is used to add the current count to the accumulator. It also
recalls the memory when pressed with no load on the scale. Up to 99 values or
full capacity of the weight display can be added. Also prints the displayed
values when Auto print is switched off.
[Smpl] This is used to enter the number of items of a sample.
[PLU] To store and recall the Product Look Up sample information.
[U. Wt./Units] This key is used to enter the weight of a sample manually. It
will also change the weighing units when other units are enabled.
[Pst] To set the upper limit for the number of items counted. When this upper
limit is exceeded the scale will sound the beeper. A secondary function is to
use it access the menus for user settings.
[Print] It is used to print the weighing data.
[Local Rem] This key is used to select the local or remote scale.
[Tare/Zero] This key has a combined Zero and Tare function. If the net weight
is below ±2% of maximum then it acts as a Zero key. This sets the zero point
for all subsequent weighing by setting the display to zero. It also tares the
scale by storing the current weight in the memory as a tare value, subtracting
the tare value from the total weight and displaying the results as a net
weight.
5.0 DISPLAYS
The scales have three display windows- Weight, Unit Weight and Count.
5.1 WEIGHT WINDOW
This consists of a 6 digit display to indicate the weight on the scale. An
arrow above the symbols will indicate the following: Low battery, Charging Net
Weight Display, “Net” Stability indicator, “Stable” Zero indicator, “Zero”
Unit in use indicator, “Lb” or “Kg”
5.2 UNIT WEIGHT WINDOW
This display will show the unit weight of a sample. This value is either
entered by the user manually or computed by the scale. The unit of measure is
either gram on all scales with kilogram selected as weighing unit or in
pounds. When the scale has determined that there is insufficient number of
samples to accurately determine the count, an arrow will be shown above
“Smpl”. When the unit weight is not large enough to determine an accurate
count, the arrow will show at “U.Wt”. When a value has been entered into the
memory, the arrow above “M+” will be on.
In both the cases the scale continues to operate and the indicators are to
alert the user of a potential problem.
5.3 COUNT WINDOW
This display will show the number of items on the scale or the value of the
accumulated count. See the OPERATION section.
An arrow above the symbols will indicate the following:
Checkweighing is active during counting, “Ck Pcs”
Checkweighing is active during weighing, “Ck Wt”
Checkweighing is active, result is above the High Limit, “High”
Checkweighing is active, result is between the Low and High Limit, “OK”
Checkweighing is active, result is below the Low Limit, “Low”
Just under the “Count” display is an LED to indicate the status of the battery
charging. When the scale is plugged into the main power the internal battery
will be charged. If the LED is green, the battery has a full charge. If it is
red, the battery requires further charging and yellow indicates the battery is
being charged.
6.0 OPERATION
The basic weighing functions are same for both the local and remote scales.
However the number of weighing divisions may be less on the remote scale
dependant on the total capacity of the load cell/s used.
Each scale (local or remote) has the ability to count parts based on the
current unit weight. This is best obtained by weighing and counting a sample
on the local scale which may have the best sensitivity. Then the scale can be
switched to the remote where large quantities can be counted.
Each scale has a separate tare value that can be entered through the keypad or
by placing a weight on the platform and pressing the [Tare/Zero] key. The tare
value for each scale is retained as the user switches between the remote and
local scales.
Either scale can be used to determine a unit weight.
When the scale is switched from local to remote, a clear display will be shown
to identify the change and the scales will count based on the tare and unit
weight currently in use for the scale selected. Display for the change is:
“S w I t C h” “L o c A L” and “S w I t C h” “r e m o t E ”
The display will be based on the 7 segment interpretations, some of the
letters are shown later. The switch from local scale to remote scale should be
possible at any time by pressing the [Local/Rem] key.
NOTE: For frequently used items, counting is made easier by using PLU numbers
(Product Look Up). Up to 100 PLU’s can be stored and recalled. Place the item
on the pan and enter the appropriate PLU number using the keypad. The scale
will display the Total Weight, Unit weight and the Count of the item in the
respective windows. See section 7.4.
6.1 ZEROING AND TARING THE DISPLAY
The Tare and Zero function are combined into one key. When the gross weight is
within ±2% of the zero, set at power on for either scale then a new zero is
set. If the gross weight is greater than ±2% then the tare function is
performed.
ZEROING
You can press the [Tare/Zero] key at any time to set the zero point from which
all other weighing and counting is measured. When the zero point is obtained
the Weight display will show the indicator at “Zero”.
The scale has an automatic re-zeroing function to account for minor drifting
or accumulation of material on the platform. However you may need to press the
[Tare/Zero] to re-zero the scale if small amounts of weight are still shown
even when the platform is empty.
TARING
Preset tare values can be used with both the local and remote scale. If a new
tare value is to be used, there are two methods for entering a tare value. The
first method uses the weight on the platform and the second uses a value to be
entered by the user.
FIRST METHOD OF ENTERING A TARE VALUE:
Zero the scale by pressing the [Tare/Zero] key, if necessary. The arrow
indicator over “Zero” will be on.
Place a container on the platform, a value for its weight will be displayed.
Press the [Tare/Zero] key to tare the scale. The weight that was displayed is
stored as the tare value and that value is subtracted from the display,
leaving zero on the display. The arrow over “Net” will be on. As product is
added only the net weight of the product will be shown. The scale could be
tared a second time if another type of product was to be added to the first
one. Again only the weight that is added after taring will be displayed.
When the container is removed a negative value will be shown. If the scale was
tared just before removing the container this value is the gross weight of the
container plus all products those were removed. The zero indicator will also
be ON because the platform is back to the same condition as it was when the
[Tare/Zero] key was last pressed.
SECOND METHOD OF ENTERING A TARE VALUE:
This method allows you to enter a value for the tare weight from the keypad.
This is useful if all containers are the same or if the container is already
full but the net weight is required and the weight of the container is known.
Remove all weights from the platform, press the [Tare/Zero] key to zero the
display.
Enter the value for the Tare weight including decimal point using the keypad,
press [Tare/Zero] to store the tare value. The weight will show a negative
value equal to the tare.
Place the container on the platform.
The display will then show the weight of the container minus the tare weight.
When the full container is placed on the platform the tare value will be
subtracted from the gross weight displaying only the net weight of the
contents.
If the value input is not consistent with the increment of the scale, the
scale will round the tare value to the nearest value possible. For example, if
a tare value of 103g is entered into the 60Kg scale with 5g readability, then
the display will show -105g.
The tare value for each scale is held in memory so that they are not lost when
the active scale changes.
6.2 MEMORY FUNCTIONS
The [M+] key will add the results of a weighing into memory, regardless of
whether the local or remote scale is being used for the weighing.
6.2.1 MANUAL ACCUMULATION
The values (weight and count) shown on the display can be added to the values
in the accumulator by pressing the [M+] key. The “Weight” display will show
the total weight, the “Count” display will show the total accumulated count
and the “Unit Weight” display shows the number of times items have been added
to the accumulation memory. The values will be displayed for 2 seconds before
returning to normal.
The scale must return to zero or a negative number before another sample can
be added to the memory.
More products can then be added and the [M+] key pressed again. This can
continue for up to 99 entries or until the capacity of the “Weight” display is
exceeded.
To observe the total value stored, press the [M+] key when the scale is at
zero. The total will be displayed for 2 seconds.
To clear the memory, first press [M+] to recall the total from the memory and
then press [CE]
to clear all values from the memory.
6.2.2 AUTOMATIC ACCUMULATED TOTAL
The scale can be set to automatically accumulate total when a weight is placed
on the scale. This eliminates the need to press the [M+] key to store values
into the memory. However the [M+] key is still active and can be pressed to
store the values immediately. In this case, the values will not be stored when
the scale returns to zero.
See Section 7 for enabling Automatic Accumulation.
6.3 PARTS COUNTING
The basic function of parts counting is same for both the scales. In order to
do parts counting it is necessary to know the average weight of the items to
be counted. This can be done either by weighing a known number of the items
and letting the scale determine the average unit weight or by manually
inputting a known unit weight using the keypad.
Either of the scales can be used to determine the sample unit weight or for
the manual entry which can be used to count using either of the scales.
It is possible to increase the accuracy of the unit weight at any time during
the counting process by entering the count displayed and then pressing the
[Smpl] key. You must ensure that the quantity displayed matches the quantity
on the scale before pressing the key. The unit weight can be adjusted based on
a larger sample quantity. This will give greater accuracy when counting larger
sample sizes.
6.3.1 WEIGHING A SAMPLE TO DETERMINE THE UNIT WEIGHT
To determine the average weight of the items to be counted place a known
quantity of the items on the scale and then enter the quantity being weighed.
The scale will then divide the total weight by the number of samples and
display the average unit weight.
Zero the scale by pressing the [Zero] key if necessary. If a container is to
be used, place the container on the scale and tare as discussed earlier.
Place a known quantity of items on the scale. After the “Weight” display is
stable enter the quantity of items using the numeric keys followed by pressing
the [Smpl] key. The number of units will be displayed on the “Count” display
and the computed average weight will be shown on the “Unit Weight” display.
As more items are added to the scale, the weight and the count will increase.
If the scale is not stable, the calculation will not be completed.
If the weight is below zero, the “Count” display will show negative count.
6.3.2 ENTERING A KNOWN UNIT WEIGHT
If the unit weight is already known then it can be entered using the keypad.
Enter the value of the unit weight using the numeric keys followed by pressing
the [U. Wt.] key within few seconds while the display is flashing. If no
action is initiated within a few seconds, the “Unit Weight” display will
revert to the previous value, otherwise it will show the new value that has
been entered.
The sample is then added to the scale and the weight will be displayed as well
as the quantity based upon the unit weight. When weighing in kilograms the
unit weight is shown in grams. When weighing in pounds the unit weight is
shown in pounds.
After the unit weight has been determined or entered, the scale can be used
for parts counting. The scale may be tared to account for the net weight as
discussed in an earlier section.
After the scale is tared, the items to be counted are added and the “Count”
display will show the number of items computed using the weight and the unit
weight.
It is possible to increase the accuracy of the unit weight at any time during
the counting process by manually entering the sample quantity and then
pressing the [Smpl] key. You must ensure that the quantity displayed matches
the quantity on the scale before pressing the key. The unit weight will be
adjusted based upon a larger sample quantity. This will give greater accuracy
when counting larger sample sizes.
6.3.3 AUTOMATIC UPDATE OF UNIT WEIGHT
The scales will automatically update the unit weight when a sample less than
the initial sample count is added. A beep will be heard when the value is
updated. It is wise to check the quantity is correct when the unit weight has
been updated automatically.
To lock the unit weight and prevent Auto-update, press [U.Wt.].
This feature is turned off as soon as the number of items added exceeds the
count used as a sample.
6.3.4 COUNT PRE-SET OR CHECK-WEIGHING
Check-weighing (or Count Pre-setting) is a procedure to cause an alarm to
sound when the net weight (or the number of items) on the scale meets or
exceeds a number stored in memory. The value to be stored is entered from the
keyboard.
SETTING OF PRESET LIMITS It is possible to set a high and low limit for either
counting or weighing (using net weight). When the [Pst] key is pressed the
user can select either counting or weighing and then set the lower and upper
limit.
For example: ACTION
Press [Pst] Press [U.Wt/Units] Press [Print] Press [Print] Press [Print]
“CHECk ” ” nEt ” ”
DISPLAYS ” if currently in the weighing mode
“CHECk ” ” CoUnt ” ” ” to toggle from weighing to counting
“Hi cnt” “0.3 2 3 4″ ” ” The current high count limit is displayed, press [CE]
to clear and change if needed. If using net weight the display will show “Hi
WEG” “lo cnt” “0.0 2 3 4″ ” ” The current low count limit is displayed, press
[CE] to clear and change if needed. If using net weight the display will show
“Lo WEG”
Return to weighing with limits set.
Clearing of either or both the limits is allowed. Both limits cleared will
disable the Preset altogether.
If Preset Weight was selected the first display would show “Hi WEG” and “Lo
WEG”.
The beeper will work as described in the Beeper Parameter.
6.4 PLU (Product Look Up)
Product Look-Up (PLU) numbers are used to store information about the commonly
used items. The Tare Weight, Description of the product and Unit Weights for a
particular item are recalled by entering the PLU number for ease of operation.
The scale is capable of storing values for the Tare weight, Description and
Unit Weight for a maximum of up to 100 PLU numbers.
Tare Weight value is required for calculating the Net Weight where a container
is used during weighing. Descriptions are used for sending data over RS-232
for viewing or printing and Unit Weight is used for parts counting.
These data should be entered against a particular PLU before the weighing
process starts so that the desired PLU’s can be recalled during the weighing
process. The data can be stored and recalled manually or by sending data over
RS-232 Interface.
6.4.1 STORING PLU’S MANUALLY
ACTIONS

12 characters in total spreading over both the displays (UNIT WEIGHT and COUNT). The display will show the PLU is saved then return to normal weighing mode.
Note:
Use the [.] key to go back to the previous digit or the [M+] key to advance to the next character.
A flashing character can be used for entering a space by pressing the [0] key for slightly longer duration.
Tare value will only be stored with PLU data if the scale is in the NET mode. If the container is less then the manual zero range which is set in “Technical parameters” (default is 2% of capacity) then the scale will be Zeroed and no tare value will be stored. To avoid this, use a larger container, reduce the zero range or use the digital tare method.
6.4.2 ENTERING DESCRIPTION MANUALLY
The description can be up to 12 characters long and can be a mix of numbers,
symbols or letters.
During the procedure to set the description the numeric keypad will work in a
similar way to a mobile telephone. Pressing a number briefly will show the
number and holding it down will scroll through all the characters.
The numbers and characters are:
1 – / 2 A B C 3 D E F 4 G H I 5 J K L 6 M N O 7 P Q R S 8 T U V 9 W X Y Z 0 [
] Where _ is a Space (Not underscore)
The limitations of the 7 segment display sometimes make it difficult to
display some letters. The characters and the displayed symbols are:
ABC DE F GH I J KLMN OPQR S TU VWX YZ – / ( )
The characters will be stored as text so the output of the RS-232 interface
will look correct.
The numbers 1 2 3 4 5 6 7 8 9 0 will be 1 2 3 4 5 6 7 8 9 0.
Note that this method is only used where alpha-numeric data is permitted. This
is used for the Description field and the User ID number, Scale ID number in
the parameters section.
6.4.3 RECALLING PLU’S MANUALLY
To recall the PLU values the user should first select either local or remote scale as the tare value stored will be specific to the scale selected.
Then press the [PLU] key, enter the PLU number (00 99) then press the [PLU] key again to recall the data.
The display will show the results of the recall for 1 second then return to weighing with the data in place.
For example:
Press [PLU]
ACTIONS
“PLU ”
DISPLAYS ” – -”
” ”
Press [2], [7] Press [PLU] After 1 second, it will return to normal weighing with the Tare and Unit Weight previously entered.
“PLU ”
” 27″
” ”
“PLU 27 ” “M 4 Nut” “Brass ”
” x x x x” ” x x x x ”
” x x”
If the [PLU] key is held down after the numeric entry, it will show the description as long as the key is pressed.
In this example the display “PLU 27 ” “M 4 Nut” “Brass if no data is stored
then it will show
“nO ” ” PLU ” “SAVE “.
” shows the description for 1 second,
If the tare value is outside the range permitted for the selected scale (For example, if the local scale is selected whereas the tare value applies to the remote scale, this would exceed the capacity of the local scale) the “Weight” display would show zero tare weight.
If the tare value stored does not match the increment of the selected scale (For example, storing – 1.446 for a scale with d=0.05) then round the tare weight depending on the scale resolution (For example, in this case, -1.45 would be used as the tare value).
If a PLU number is recalled that does not have any information stored against it, the scale will continue to work with Tare and Unit weight unchanged.
NOTE: PLU’s can be stored and recalled using RS-232 Interface (see section 11.1 and 11.2 of this user Manual).

8.0 BATTERY OPERATION
The scales can be operated from the battery. The battery life is approximately
70 hours if only the basic unit is used and the backlight is not used. If the
backlight and a second platform is used the battery life will be reduced.
When the battery needs charging the arrow above the low battery symbol under
the “Weight” display will turn on. The battery should be charged as soon as
the arrow above the symbol is on. The scale will still operate for about 10
hours after which it will automatically switch off to protect the battery.
To charge the battery simply plug into the mains power. The scale need not to
be turned on.
The battery should be charged for 12 hours for full capacity.
When the power adapter is applied the battery will be charged. The battery
symbol will increment as shown.

9.2 STORING DATA VIA RS232
To store data the commands are:
SUIDxxxxxx
Store user ID data Store scale ID data Store text data for PLUxx
When PLU text data is stored the Scale stores current unit weight and current
tare value along with the PLU number.
For the SPLU command the data is: PLU number (2 characters), (Comma)
description (max 12 characters).
If the fields are less than the maximum all characters need not be used.
9.3 PLU ENTRY USING RS-232 INTERFACE
This method enables the user to send the data from a PC program as well as
from the keypad. The most common PLUs can be stored and recalled from the
scale memory. Other PLU data can be stored on a PC, then the Description (text
data), Unit Weight and Tare Weight data can be sent from the PC for the PLUxx
(where xx can be any desired number up to 99). This can then be used or over-
written during operation.
OPERATION:
Send Tare Weight data to set any tare value to be stored with PLU. i.e. “T
1.45”
Send the Unit Weight to be stored with PLU. i.e. “U0.015”
Send PLU text data to be stored with current Tare and U/W values. i.e.
“SPLU27, M4 Nut Brass”
Any information stored for the Tare Weight, Description and the Unit weight
will be stored in the scale and can be recalled for use in the future.
