JC series dual counting scale user’s guide

SECTION1 INTRODUCTION

The JC 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 store detailed information on the products
that are used often (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 pan.

All the keypads are sealed, color 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, pre-set
tare and an accumulation facility that allows the count to be stored and recalled as
accumulated total.

The scales have an expanded bi-directional RS-232 interface for communication with
a PC or printer.

SECTION3 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

3.2.1 SETTING UP THE LOCAL SCALE

• The JC 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 center of the level and the scale is supported by all
four feet.

- 3-

JC series dual counting scale user’s guide

• Attach the power supply cable to the connector on the right side of the scale base.

Plug in the power supply module. The power switch is located at the right side of the
scale base.

• The scale will show the model number in the “Weight” display window (JC 15- where

15 denotes the maximum capacity of the scale in Kg) and the current software
revision numbers in the “Unit Weight” display window .

• Next a self-test is followed. At the end of the self-test, it will display “0” in all three

displays, if the zero condition has been achieved.

3.2.2 SETTING UP THE REMOTE SCALE

• The JC Series can be connected to any size of load cell type weighing base via the

Remote scale port on the left 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 center.

• Press Local/Rem key and test weighing performance.

3.2.3 REMOTE SCALE CONNECTION

The cable for the load cell goes to a 9 pin d-subminiature plug connector with the
following connections:

Pin numbers Connection
Pins 1,2 Excitation+(5V)
Pins 4,5 Excitation- (0v)
Pin 7 Signal­Pin 8 Signal+

(The sense wires connections of a six wire load cell are not used but can be
connected to the respective Excitation pins).

3.2.4 REMOTE SCALE SET UP

The remote scale should set for a realistic resolution with respect to the input provided
by the load cell/s.

If a single 2mV/V load cell is fitted and more than 60% of the load cell is used for full
capacity then the high output of >6mV 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, for example: 300kg x 10g.

It will also be possible to sample on the remote scale with the same accuracy as the
Local.

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 2mV/V 1000kg load cells for a scale of 1000kg

- 4 -

JC series dual counting scale user’s guide

capacity then the span output at full scale will be only 2.5mV.
In this situation the resolution should be reduced to give a good number of ADC
counts per displayed division, for example, set to 1:5000 or 1000kg x 0.2kg.

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.

For best performance ensure a minimum of 0.1uV/d.

SECTION4 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.

M1 ~ M5

Direct PLU key. To store and recall the Piece Look Up sample information quickly.

PLU

To store and recall the Piece Look Up sample information. 100 PLUs with description,
unit & tare weight.

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 for the
backlight control setting.

Local/Rem

This key is used to select the local or remote scale.

Tare

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.

Zero

sets the zero point for all subsequent weighing by setting the display to zero.

- 6 -

JC series dual counting scale user’s guide

SECTION5 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,
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 High Limit, “Low”

• Just under the “WEIGHT” 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.

JC series dual counting scale user’s guide

SECTION6 OPERATION

• The basic weighing functions are same for both the scales- local and remote.

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 performing 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 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:
“chAngE” ”LocAL“ and “chAngE” ”remotE “, The display will be based on the 7
segment interpretations, some of letters are shown later.

• The switch from local scale to remote scale should be possible at any time by

pressing the Local/Rem key or if the user enables the function it can happen anytime
the weight on the remote scale changes from negative value or zero to a positive
value greater than 50d.

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. See section 6.4 on
PLU for details. Place the item on the pan and enter using the keypad “PLUxx” (where
xx is the PLU number associated with that item). The scale will display the Total
Weight, Unit weight and the Count of the item in the respective windows.

6.1 ZEROING AND TARING THE DISPLAY

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.

6.1.1 ZEROING

• You can press the 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
Zero to re-zero the scale if small amounts of weight are still shown even when
the platform is empty.

- 8 -

JC series dual counting scale user’s guide

6.1.2 TARING

Select the local or remote scale as applicable by pressing the Local/Rem key.
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 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 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 that were removed. The zero indicator will also
be ON because the platform is back to the same condition as it was when the

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 Zero key to zero the display.

• Enter the value for the Tare weight including decimal point using the keypad,
press Tare 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.

6.1.3 TARING THE REMOTE SCALE

Select the remote scale by pressing the Local/Rem key and then follow the same
procedure for taring as mentioned in the above sections.

- 9-

JC series dual counting scale user’s guide

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 PARAMETERS Section on 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.

- 10 -

JC series dual counting scale user’s guide

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, “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
Smpl. 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
providing 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.

- 11-

JC series dual counting scale user’s guide

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 DISPLAYS
Press Pst
Press U.Wt/Units

“PST ” “ nEt “ “ “ if currently in the weighing mode
“PST ” “ cnt “ “ “ to toggle from weighing to counting

“Hi cnt” “0.3 234” “ ” The current high count limit is

Press Tare

displayed, press CE to clear and change if needed.
“lo cnt” “0.0234” “ ” The current low count limit is

Press Tare
Press Tare

displayed, press CE to clear and change if needed.
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 net” and “lo net”.

• 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 5 direct PLU and up to 100 indirect 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.

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 - / \

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:

A B C D E F G H I J K L M N O P Q R S T U V

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

X Y Z - / \ ( )

The characters will be stored as text so the output of the RS-232 interface will be
correct.

The numbers 1 2 3 4 5 6 7 8 9 0 will be 1234567890

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

• In this example the display “PLU 27 ” “M 4 Nut“ “Brass “ shows the description for
1 second, if no data is stored then it will show “PLU 27” “ “ “ “.

• 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.

SECTION8 BATTERY OPERATION

• The scales can be operated from the battery if desired. The battery life is
approximately 70 hours if only the basic unit is used. If 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.

• Just under the “Count” display is an LED to indicate the status of 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 is nearly discharged and yellow indicates the battery is nearly charged.

NOTE: It is recommended that the battery be charged before using the scale when the
unit has been unpacked.
