• The ABK/AFK scales provides an accurate, fast and versatile
general purpose weighing scales with parts counting, percent
weighing and check-weighing functions.
• The ABK/AFK has LEDs to indicate when a weight is below the
low limit, between the limits or above the high limit next to the
display. These can work in conjunction with an audible alarm for
check weighing as well as LCD showing LO, OK and HI.
• The ABK/AFK is supplied with a RS-232 bi-directional interface
and real time clock (RTC).
• The ABK/AFK has a sealed keypad with colour coded membrane
switches and a large easy to read liquid crystal type display (LCD)
supplied with a backlight.
• Includes automatic zero tracking, semi-automatic tare and
accumulation facility that allows the weight to be stored and
recalled as an accumulated total.
The ABK/AFK scales have already been adjusted to work with a platform and
have been configured for this application. The platform and indicator have
been calibrated as a pair and must be used together .
3.2 LOCATING
•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 airconditioning vents.
•
Keep the scales clean. Do not stack material on the
scales when they are not in use.
•The pillar is attached to the base using a bracket that must be
attached to the base frame first using the 4 bolts supplied. The
pillar is secured to the bracket using 2 sets of screws. The cable
from the base to the indicator module is run through the tube and
taken out through the support at the top. Excess cable can be
stored within the tube.
•The ABK/AFK Series comes with a stainless steel platform
packed separately. Place the platform in the base.
•Level the scale by adjusting the four feet. If the scale rocks re-
adjust the feet.
•Attach the indicator module to the pillar by securing it with the 2
thumb screws provided. Attach the cable from the base to the
connector on the rear of the indicator.
•Attach the power to the indicator. Press the [On/Off] key. The
software revision number will be displayed followed by a self-test
showing all digits before the zero is displayed along with the unit
of weight that was selected last.
Selects the Functions of the scale. If the scale is
weighing, it will select parts counting. If it is not in
weighing mode, it will return the user to weighing.
A secondary function (C) is to act as a clear key when
setting values for Parameters.
Sends the results to a PC or a Printer using the RS232 interface. It also adds the value to the
accumulation memory if the accumulation function is
not automatic.
A secondary function (ESC) is to return to normal
operation when the scale is in a Parameter setting
mode.
To switch on and switch off the indicator.
The ABK/AFK will store the weighing unit in use and
the check weighing values currently in memory when
power is off.
The LCD display will show a value and a unit to the right of the digits.
In addition the LED’s above the display will show when a weight is below or
above check-weighing limits.
Other symbols will show when a weight has been tared (NET) the scale is at
zero and stable, if a value has been stored in memory or when the animal
weighing function has been enabled. A battery symbols will show the state of
charge of the internal battery.
• You can press the [Z/T] key at any time to set the zero point. This
will usually be necessary when the platform is empty. When the
zero point is obtained the display will show an indicator for 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 [Z/T] key to rezero the scale
if small amounts of weight are shown when the platform is empty.
6.2 TARING
• Zero the scale by pressing the [Z/T] key if necessary. The
“ZERO” indicator will be ON.
• Place a container on the platform, a value for its weight will be
• Press the [Z/T] 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 “NET” indicator
will be ON. As a 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 was
removed. The “ZERO” indicator will be on to indicate that the
platform is back to the same condition as it was when zero was
last set.
• To delete a Tare value, press [Z/T] when the pan is empty.
6.3 WEIGHING A SAMPLE
To determine the weight of a sample, first tare the empty container if it is to
be used and then place the sample in the container. The display will show
the net weight of the sample and the units of weight currently in use.
If parts counting is enabled, See section 7.4, it is possible to count parts using
a sample of the parts to determine average piece weight.
• Before starting, tare the weight of any container that may be used,
leaving the empty container on the scale. Place a known number
of samples in the container, if used. The number should match
the options for parts counting, i.e., 10, 20, 50, 100 or 200 pieces.
• When the scale is showing weight, pressing the [Pcs/] key will
start the parts counting function.
• The scale will show “P 10” asking for a sample size of 10 parts.
Change the sample size to the desired quantity by pressing the
[Pcs/] key. It will cycle through the options: 10, 20, 50, 100,
200 and back to 10.
• Press the [Z/T] key again when the number matches the number
of parts used as the sample. As more weight is added the
display will show the number of parts (Pcs).
Pressing the [Unit/] key will display the unit weight (g/pcs), pressing it
second time will display the net weight (pcs and kg) and the third time, it will
be the count again (pcs).
