1 INTRODUCTION
The QHD 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 most (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-directionalRS-232 interface for communication with a
PC or printer.

SECTION 3 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 QHD 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-
• 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 (QHD 15-
where 15 denotes the maximum capacity of the scale in Kg) and the current software
revision numbers in the “Unit Weight” display window .
•Nextfollowsa self-test. At the end of the self-test, itwill display “0” in allthree displays,
if the zero condition has been achieved.
3.2.2 SETTING UP THE REMOTE SCALE
• The QHD 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 connects to a DB 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 beconnected
to the respective Excitation pins).
3.2.4 REMOTE SCALE SET UP
See Section 12 Technical Parameters to set capacity, etc.
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 utilized then
- 4 -
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 scaleof 1000kg 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.

SECTION 4 KEY DESCRIPTIONS
0-9, •
Thesekeys are used to manually enter a value for tare weights, unit weight andsample
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 Piece 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 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
setsthe zero point for all subsequent weighing by setting the display to zero.
- 6 -
SECTION 5 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 “Count” display is an LED to indicate the status ofthe 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.
- 7-
SECTION 6 OPERATION
• The basic weighing functions are same for both the scales- local and remote.
However the number of weighing divisions maybe 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 thechange 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 thatitem). Thescale 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 -
6.1.2 TARING
Select the local or remote scale as applicable by pressing the Local/Rem key.
Preset tare values can be used withboththelocal 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 thekeypad. 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 inmemory 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.
6.2 MEMORY FUNCTIONS
- 9-
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 secondsbefore 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 thememory 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 canbe 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 thecounting
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
- 10 -
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 bedisplayed 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 thekeypad.
• 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. Ensurethat the quantity displayedmatches the quantity on the scalebefore
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 sampleless 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
- 11-
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 “PST ” “ nEt “ “ “ if currently in the weighing mode
Press U.Wt/Units
“PST ” “ cnt “ “ “ to toggle from weighing to counting
Press Tare
“Hi cnt” “0.3 234” “ ” The current high count limit is
displayed, press CE to clear and change if needed.
“lo cnt” “0.0234” “ ”The current low count limit is
Press Tare
displayed, press CE to clear and change if needed.
Press Tare 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 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.

“ x x x x“ “ x x x x ” “ x x“
weighing with the Tare and Unit Weight
previously entered.
• 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 “ 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.
PLU’s can be stored and recalled using RS-232 Interface (see section 9.1 and 9.2
of this user Manual).

SECTION 8 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 batterysymbol 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 mainspower. 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 powerthe 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.

SSIDxxxxxx <CR> Store scale ID data
SPLUxx,xxxxxxxxxxxx <CR> Store text data for PLUxx
When PLU text data is stored the Scaleused, current unit weight and current tare value
is also stored to that PLU number.
For the SPLU command the data is: PLU number (2 characters), (Comma) description
(max 12characters).
If the fields are less than the maximum all characters need not be used.
9.3 PLU ENTRY USING RS-232 INTERFACE
- 20 -
This will allow the scale data to be sent 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 text data, unit weight and tare data can be
sent from the PC to PLU00. This can then be used and over written each operation.
OPERATION:
• Send tare data to set any tare value to be stored with PLU. i.e. “T0.150” <CR>. If
no tare is needed then you may send T0 to delete any present tare data.
• Send the unit weight to be stored with PLU. ie. “U12.3456” <CR>
• Send PLU text data to be stored with current TARE and U/W values. ie.
“SPLU01,Parts” <CR>
