1.0 INTRODUCTION
•The CFW series of scales provide an accurate, fast, versatile series of
general purpose weighing scales with counting and check-weighing
functions.
•There are 2 series of scales- CFW scales are kilogram only scales and
the CFWa scales offer changeable unit from pounds to kilograms. The
scales share the same functions but special instructions will be given
for the CFWa series to be able to change the weighing units.
•There are 4 models in each series with the maximum capacities up to
600 kg /1320 lb.
•They all have stainless steel weighing
platforms on a Steel base assembly and
a display module mounted on a pillar
attached to the base.
•All the keypads are sealed and have
colour coded membrane switches.
•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 and an accumulation facility that allows the
individual weights to be stored and recalled as an accumulated total.
•The scales have an optional bi-directional RS-232 interface for
communicating with a PC or printer.

display shows zero.
A secondary function is of "Enter" key used when
setting up the value for the Parameters.
[Tare] or
Tares the container. Stores the current weight of the
container in memory as tare value, subtracts the tare
value from the total weight of the container and the
sample and shows the results. This is the net weight.
The user can also enter a value using the keypad to be
stored as the tare value.
A secondary function is of incrementing the active
digit when setting a value for Parameters.
[Pcs] Selects parts counting. Used to set the sample
quantities while parts counting.
A secondary function is to move the active/flashing
digit to the left when setting values for the
Parameters.

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.
[Print/M+] or
Sends the results to a PC or a Printer using the RS-
232 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.

6.0 OPERATION
6.1 ZEROING THE DISPLAY
•You can press the [Zero/Enter] 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 [Zero/Enter] 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 [Zero/Enter] key if necessary. The
“ZERO”indicator will be ON.
•Place a container on the platform, a value for its weight will be
displayed.
•Press the [Tare/Ï]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 "GROSS" indicator
will be OFF and "TARE" indicator will be ON. As a product is added
only the net weight of the product will be shown. The scale could be
@Adam Equipment Company 2005
10

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 the [Zero/Enter] key was last
pressed.
•To delete a negative Tare value, press [Tare/Ï] 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.
6.4 PARTS COUNTING
•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
[Tare/Ï]key. It will cycle through the options: 10, 20, 50, 100, 200
and back to 10.
@Adam Equipment Company 2005

•Press the [Zero/Enter] 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 [Pcs] 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).
•Press the [Func/C] key to return to normal weighing or to start
counting a different sample.

6.5 CHECK-WEIGHING
Check-weighing is a procedure to cause an alarm to sound when the weight on
the scale meets or exceeds values stored in memory. The memory holds
values for a high and a low limit. Either or both can be used.
See PARAMETERS Section for the procedure. To set the limits, "F0 H-L" is used.
After limits have been set the Check-weighing function is enabled.
When a weight is placed on the scale the arrows will show if the weight is above
or below the limits and the beeper will sound as described below.
BOTH LIMITS SET The display will show OK and the beeper will sound when the
weight is between the limits.
LOW LIMIT SET HIGH LIMIT is set to zero
The display will show OK and the beeper will sound when the
weight is less than the Low Limit. Above the Low Limit the
display will show HIGH and the beeper will be off.
HIGH LIMIT SET LOW LIMIT is set to zero
The display will show LOW and the beeper will be off when the
weight is less than the High Limit. Above the High Limit the
display will show OK and the beeper will be on.
BOTH LIMITS SET.
LOW IS SET GREATER
THAN HIGH
The beeper will never sound and the display will show LOW if
the weight is less that the LOW limit, and HIGH if the weight is
greater than the Low Limit.
NOTE: Weight must be more than 20 scale divisions for checkweighing to
operate.

Checkweighing during Parts Counting
To disable the Check-Weighing function enter zero into both limits by pressing
the [Func/C] key when the current limits are shown then pressing [Zero/Enter]
to store the zero values.
6.5 ACCUMULATED TOTAL
•The scale can be set to accumulate manually by pressing the
[Print/M+] key. See the PARAMETER Section for details of setting
the Parameter "F5 PRT". The accumulation function is only available
when weighing. It is disabled during parts counting.
•The weight displayed will be stored in memory when the [Print/M+]
key is pressed and the weight is stable.
•The display will show "ACC 1" and then the total in memory for 2
seconds before returning to weighing. If the optional RS-232
interface is installed the weight can be output to a printer or PC.
