1.0 INTRODUCTION
 The ACBplus series of scales are simple and easy to use.
 The scales can be operated with an A.C. adapter or using an
internal rechargeable battery.
 The weighing process is fast and accurate, making it suitable for the
general purpose weighing applications, parts counting, percentage
weighing functions, etc.
 There are 7 models in this series with capacities ranging from 150
grams to 3 kilograms.
 All models include automatic zero tracking, automatic tare,
accumulation facility that allows the weight to be stored and recalled
as an accumulated total and bi-directional RS-232 interface for
communicating with a PC or printer.
 All have stainless steel weighing platforms on an ABS plastic base
assembly.
 Keypads are sealed with colour coded membrane switches.
 The scales have an optional weigh below facility.
 The displays are large, easy to read liquid crystal type displays
(LCD). It is provided with a backlight and also a bar-graph at the
bottom to display the weight of the item on the pan with respect to
the capacity of the scale.
 The LCD normally shows the weight and the units of the weight
selected previously (Grams, Carats, Pounds, etc). See section 5.1
for details on Units.

3.0 INSTALLATION
3.1 LOCATING THE SCALE
 Avoid extreme temperatures. Do not place the scale in direct
sunlight or near air conditioning vents. Avoid air movement
such as from fans or opening of doors and windows.
 Avoid unsuitable tables. The table or floor must be rigid and
not vibrate. Do not place near vibrating machinery.
 Avoid unstable power sources. Do not use the scale near
any large user of electricity such as welding equipment or
large motors.
 Avoid high humidity that might cause condensation. Avoid
direct contact with water. Do not spray or immerse the scales
in water.
 Keep the weighing area clean.
 Do not stack material on the scale when not in use.
 Protect the scale from extreme temperatures, vibration and
dust.
3.2 SETTING UP THE SCALE
 Remove the Shipping Protection screw from the bottom of
the base.

 The scale comes with a stainless steel platform, packed
separately.
 Place the platform in the receptacles on the top cover.
 Do not press with excessive force- it 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.
 Turn the power on by pressing the [On/Off] switch.
 The unit will display the model number and the software
revision number for a while and then will count down
performing a self-test.
 When ready the display will show zero along with the
weighing unit selected during the last operation.
3.3 BATTERY CHARGING
 The scales can be operated from the internal rechargeable
battery or using an A.C. Adapter. The battery life is
approximately 24 hours depending on the usage of the
backlight.
 The display will show an indication when the battery needs to
be charged. To charge the battery, plug in the AC adapter at
the back of the scale and attach it to the main power supply.
The charging indicator at the left top corner of the LCD will
be on.

3.5 KEY DESCRIPTIONS
KEYS PRIMARY FUNCTION SECONDARY FUNCTION
[On/Off]
To turn the scale On or Off.
----
[Zero]
Sets the zero point for all
subsequent weighing. The display
shows zero.
A secondary function is of "Enter"
key for setting parameters or other
functions.
[Tare]
Tares the scale. Stores the current
weight in memory as a tare value,
subtracts the tare value from the
weight and shows the results. This
is the net weight.
Pressing [Tare] again will cancel
the tare value.
[%]
Enters the percent weighing
function.
When in percentage mode, press
[%] key to return to normal weighing
mode.
[Smpl]
Use this key to enter counting
mode from the normal weighing
mode,
A secondary function allows the
user to return to normal weighing
mode while in counting mode. It
also clears the accumulated value
from the memory when pressed
during recalling the total.
[Mode]
Pressing this key will cycle through
the weighing units which are
enabled. It also scrolls through the
options during setting up a
parameter.
Displays the unit weight, total
weight and the count when in the
parts counting mode.
[Print]
To print the results to a PC or
printer using RS-232 (A USB
interface will be available shortly).
It also adds the value to the
accumulated memory if the
accumulation function is not
automatic.
Secondary function is to return to
normal operation when the scale is
in a parameter setting mode.

4.0 OPERATION
4.1 ZEROING THE DISPLAY
 Press the [Zero] key when the platform is empty.
 [Zero] key may be pressed at any time to set the zero point
from which all other weighing and counting is measured.
 When the zero point is obtained the “O” indicator will be on in
the left bottom corner of the LCD.
 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] key to re-zero
the scale if small amounts of weight are shown when the
platform is empty.
4.2 TARING
 Zero the scale by pressing the [Zero] key, if necessary.
 The “O” indicator 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. It is subtracted from the
displayed value, leaving zero on the display. The NET
symbol will be on at the right top corner to indicate that the
weight displayed is the net weight.
 As the product is added, only the net weight 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 “O” indicator will also be on because the platform is back
to the same condition as it was when the [Zero] key was last
pressed.
 To cancel the tare value, press [Tare] again.

4.3 WEIGHING
 After zeroing the display and taring the container, place the
sample in the container to determine the weight of the
sample. The weight will also be displayed through a bar-
graph at the bottom of the LCD.
 The display will show the weight and the units of weight
currently in use. The stable indicator will be on. To
change the weighing units, press [Mode] to cycle through the
options of units those are enabled. See the Parameter
section to enable or disable the weighing units.
 The accumulated value in the memory will be cleared when a
new weighing unit or during recalling the memory, %
weighing or parts counting is selected.
4.4 PERCENT WEIGHING
 The scale will allow a sample weight to be shown as 100%.
Then any other weight placed on the scale will be displayed
as a percentage of the original sample.
 For example is 350g is placed on the scale and the [%] key
is pressed the display will show 100.00%. Removing the
350g weight and place a 300g weight on the scale. The
display will show 85.71% as 300g is 85.71% of 350g.
 Note: The scale may jump by large numbers unexpectedly if
small weights are used to set the 100% level. For example, if
only 23.5g is on a scale with 0.5g increments and the scale is
set to 100%, the display will show 100.00%. However, a
small change of weight will cause the display to jump to
102.13%, as one scale division (0.5g) increase to 24.0g will
be equivalent to a 2.13% increase.
 Pressing the [%] key again will return the scale to normal
weighing.
