The "TOTA"L icon displays the scale measurement mode as referenced in the table
below. CW250 Measurement Modes
Control Functions
ON / OFF
Press the On/Off key to apply power to the weighing system electronics. When
power is first applied, the weighing system rapidly performs self-tests of the pad and the
internal electronics. When the tests have been successfully completed, the scale
begins weighing. If a problem is detected during self-test, the screen will display an
error message. To turn the scale off, press the On/Off key. The CW250 retains the
setup information and calibration in a special memory device (non-volatile memory) that
is not affected by power loss or battery condition.
PRINT / ACCUMULATE
Press the Print/Accumulate button to print and/or accumulate weights. The function is
dependent on the current print mode setting. When using the accumulated total
function, press the PRINT /ACCUMULATE button to add the total to the accumulated
total. (New accumulated total = total weight (all scales in system) + old accumulated total)
LOCAL/TOTAL
Press the LOCAL/TOTAL button to toggle the scale between local weight and total
weight. The local weight is the weight on that scale only. The total weight shown is the
weight on all of the scales in the system. The display will be in local mode unless the
"TOTAL" icon is displayed.
If the serial output is set to mode 2 or 3 and a successful accumulation has occurred,
press the LOCAL/TOTAL button to toggle the display through the current local weight,
current total weight, accumulated total, and the number of accumulations that make up
the total.
NOTE:
If the system is not setup correctly, an "error" icon and the message ""
will be displayed when attempting to view the total weight.

ZERO
The ZERO key will reset the weight on a scale to read zero (either lb or kg unit of
measure). If the ZERO key is pressed when a pad holds weight, the current weight
becomes the zero condition for the pad. The ZERO feature can be useful to cancel the
weight of weighing fixtures such as tail cones or wheel chocks. When the weight is
removed, a negative weight is displayed until the system is re-zeroed. The ZERO
function is also used when the scale shows a non-zero value with no weight on the
pads. NOTE: The system includes a feature called Auto Zero Tracking (AZT). AZT
corrects for slight zero changes during normal operation. An example of a zero change
could be a buildup of dirt on the pads.
The ZERO key can also be used to clear the accumulated total. Press and hold the
ZERO key until the display screen shows ".", then release the ZERO key. The
accumulated total and the accumulation number will be reset. All scales connected in
the system through interconnect cables will also be zeroed. The entire system can be
zeroed with one press of the ZERO key.

Totalizing Setup
The CW250 scale must be setup correctly in order to communicate with other scales in
the system. If the system is not setup correctly, an "error icon" and message “ “will
be displayed when attempting to view the total weight.
1. To begin Totalizing Setup, press the LOCAL/TOTAL and ZERO buttons
simultaneously.
2. The message "" will be displayed. Press the PRINT/ACCUMULATE button.
A number will be displayed followed by 3 dashes. The number displayed is the
scale number. Use the LOCAL/TOTAL button to increment and the ZERO button
decrement the number. When the desired number is displayed, press the
PRINT/ACCUMULATE button.
3. The message "" will be displayed. Press the PRINT/ACCUMULATE button.
The display will show three dashes followed by a number. The number
represents the total number of scales in the system. Use the LOCAL/TOTAL
button to increment and the ZERO button to decrement the number. When the
desired number is displayed, press the PRINT/ACCUMULATE button. NOTE:
The maximum number of scales in a system is 32.
4. If the scale number is "1", the display will issue a prompt confirming the scale
designation is "". Press the PRINT/ACCUMULATE button. Use the
LOCAL/TOTAL or the ZERO button to toggle either "" or "". A scale with a
HOST designation controls the entire scale network. The setting should be set to
"yes" if the scale network consists of scales only. If the system uses an external
device such as a PDA or PC to view the weights, the display setting should be
set to "no" because the external host device controls the scale network. Press
the PRINT/ACCUMULATE button to save the setting.
SETUP EXAMPLE: Setup for two scales. First Scale: Enter "01" for the first scale
number. Enter "02" for the total number of scales. Enter "yes" for the "Host"
setting. Second Scale: Enter "02" to identify the second scale and "02" for the
total number of scales.

ACCUMULATE NOTE: The scale will not accumulate when the weight is
negative, zero, or if the weight is in motion. The protections are added to ensure
only valid readings are accumulated into the total. An error message "." will
be displayed when any of the three conditions are present. At the completion of
a successful accumulation, the scale must be returned to zero before the next
accumulation can be attempted. If an attempt is made to accumulate the next
weight before allowing the scale to return to zero, the error message ".” will
be displayed.

Accumulated Total
The CW250 scale platform can be used separately, in pairs, or in groups to measure a
support load or a total weight across the scales connected to the system in one
weighing procedure. The Accumulated Total feature "accumulates" the weights as each
individual load is weighed.
To use the Accumulated Total feature, each scale in the system must be numbered
correctly. The scale selected to print from or to display the accumulated total must have
the print mode set to either the "Accumulating Print Axle" or "Accumulating Print
Standard" mode.
Accumulating Print Axle
If the "Accumulating Print Axle" mode has been selected for the designated scale,
press the PRINT/ACCUMULATE button to add the current total weight to the
accumulated total weight. If the scale designated as the "Accumulating Print Axle"
mode scale is connected to a printer, a print ticket will be printed. The print ticket format
is in reference to the individual wheels and axles of the vehicle being weighed or is
formatted in a standard weight accumulation mode.
The following example shows a 4-scale system with two separate weighings having
been conducted and accumulated.
Subgroup #1: "WHL 1" is scale number 1 and "WHL 2" is the second scale. "AXL 1"
shows the total weight of scale number one and two. "AXL2" shows the weights from
scale number three and four. Both the subtotal and accum total weights reflect the
Subgroup #1 totals
Subgroup #2": WHL 1" is scale number 1 and "WHL 2" is the second scale. "AXL 1"
shows the total weight of scale number one and two. "AXL2" shows the weights from
scale number three and four. The subtotal grp 2 weight reflects the total weight for the
subgroup #2. The accum total weight reflects the Subgroup #1 total and Subgroup #2
total.

When a successful accumulation has occurred, press the LOCAL/TOTAL button to
toggle the display through the current local weight, current total weight, accumulated
total, and the number of accumulations that comprise the total weight.
ACCUMULATE NOTE: The scale will not accumulate when the weight is negative, zero,
or if the weight is in motion. The protections are added to ensure only valid readings are
accumulated into the total. An error message "." will be displayed when any of the
three conditions are present. At the completion of a successful accumulation, the scale
must be returned to zero before the next weight accumulation can be initiated. If an
attempt is made to accumulate the next weight before allowing the scale to return to
zero, the error message "." will be displayed.
The accumulated total weight can be viewed only on the designated scale. When the
PRINT/ACCUMULATE button is pushed, the display will show the message ". X" as
the system accumulates the next reading and sends it to print. ("X" denotes the number
of accumulations for the session) When a successful accumulation has occurred, press
the LOCAL/TOTAL button to cycle the display to show the number of accumulations,
current local weight, current total weight on all scales, and the accumulated total.
When the local weight, current total weight, or accumulated total is displayed, the
TOTAL icon will be lit, flashing or turned off.
Accumulating Print Standard
The "Accumulating Print Standard" mode will display the total weight of multiple items
weighed on one or more scales. The following example depicts a 1-scale system with
three separate loads (950 lb., 1000 lb. and 1500 lb.) being weighed and accumulated.

Accumulating Procedure
1. When the system is setup and operating correctly, select the scale to be used to
accumulate the weights. Any scale can be designated, but once selected, the scale
must be used to accumulate all weights until the weighing is complete. The scale
should be set to the desired accumulate mode of 2 or 3 (Refer to the "Serial Output
Setup" section for additional information). If using a printer, the scale directly
connected to the printer should be designated as the scale to be used for
accumulation.

2. When the first group of items to be weighed is stable on the scales, press the
PRINT/ACCUMULATE button. If using a printer, a print ticket with all weights will be
printed. The display will return to the setting the accumulation was obtained from.
The weight from the first group will become the accumulated total. The
accumulated total can be displayed by pressing the LOCAL/TOTAL button when
the TOTAL icon is flashing. An accumulation cannot be made in standard mode if
the scale is in the Accumulation Print mode with the TOTAL icon flashing. When
the accumulation is complete, remove the first group of items from the scale(s).
3. When the next group of items to be weighed is stable on the scale(s), press the
PRINT/ACCUMULATE button. The total weight will be added to the accumulated
total. If using a printer, a print ticket with all weights will be printed.
4. Repeat step 3 as required for additional weigh groups. If the accumulated total
becomes too large to display, the message "" and an error icon will be
displayed.
5. When finished, the accumulated total weight can be cleared by pressing and
holding the ZERO button until the display shows ".".The display will clear the
accumulated total and the number of accumulations.
ACCUMULATE NOTE: The scale will not accumulate when the weight is negative,
zero, or if the weight is in motion. The protections are added to ensure only valid
readings are accumulated into the total. An error message "." will be
displayed when any of the three conditions are present. At the completion of a
successful accumulation, the scale must be returned to zero before the next weight
accumulation can be initiated. If an attempt is made to accumulate the next weight
before allowing the scale to return to zero, the error message ".” will be

Setting Mode Menu Parameters
1. Press the PRINT/ACCUMULATE and ZERO buttons simultaneously. The display
will show the message ".". Press the PRINT/ACCUMULATE button. The
flashing display shows the current setting. Press the ZERO or the LOCAL/TOTAL
buttons to toggle between Auto, On and Off. When "Auto" is selected (default
setting), the backlight will automatically light up when low level light conditions are
detected. When the desired setting is displayed, press the PRINT/ ACCUMULATE
button to save.
2. The display will show "". Press the PRINT/ACCUMULATE button. The flashing
digit shows the current setting. When the weight displayed is equal to or greater
than the set point, the corresponding icon is displayed on the LCD screen. During
normal weighing mode, the S1 icon on the display will light up when the weight is
greater than or equal to Set Point 1. Use the LOCAL/TOTAL button to advance the
number and the ZERO button to move the flashing number to the left. When the
desired set point number is displayed, press the PRINT/ACCUMULATE button.
3. The display will show "". Press the PRINT/ACCUMULATE button. The flashing
digit shows the current setting. During normal weighing mode, the S2 icon on the
display will light up when the weight is greater than or equal to set point 2. Use the
LOCAL/TOTAL button to advance the number and the ZERO button to move the
flashing number the left. When the desired set point number is displayed, press the
PRINT/ACCUMULATE button.
4. The display will show "". Press the PRINT/ACCUMULATE button. The display
will show the current version of firmware loaded on the scale. Press the
PRINT/ACCUMULATE button.
5. The display will show the message ".". Press the PRINT/ACCUMULATE button.
The flashing digit shows the current setting. The number reflects the number of
readings that be averaged together before the reading is sent to the display. Higher
values will result in a more stable reading, but will take longer to process the final
value. The scale updates at 4Hz, so an Average Rate of "8" equates to 2 seconds of
averaging. Enter a "1" to disable averaging. Use the Lb/Kg button to the advance
the number and the ZERO button to move the flashing number to the left. When the
desired average rate setting is displayed, press the Mode button.
6. The display will show ".". Press the Mode button. The flashing digit reflects the
current Average Threshold setting. The setting enables dynamic averaging, which
can improve the settling time of a large Average Rate. If the scale detects a large
weight change, it will temporarily suspend averaging, jump to the new weight, and
resume averaging. Enter a value between 1 and 10000 to set the threshold (in
display divisions) at which the dynamic averaging activates. Enter "0" to disable
dynamic averaging. When the display shows the desired setting, press the
PRINT/ACCUMULATE button.

7. The display will show ".". Press the PRINT/ACCUMULATE button. The
flashing digit shows the current setting. The number displayed is the number of
minutes the scale can remain idle before it automatically shuts down. Setting the
number to "" will disable the function and the scale will never automatically shut
down. Use the LOCAL/TOTAL button the advance the number and the ZERO button
to move the flashing number to the left. When the display shows the desired
number, press the PRINT/ACCUMULATE button.
8. The display will show "". Press the PRINT/ACCUMULATE button. The flashing
digit shows the current setting. The Print Mode setting enables one of three scale
print modes (0 for on-demand, 1 for continuous, 2 for accumulating total axle format
and 3 for accumulating total standard format). Use the LOCAL/TOTAL button to
increment and the ZERO button to decrement the number. When the display shows
the desired number, press the PRINT/ACCUMULATE button.
9. The display will show "". Press the PRINT/ACCUMULATE button. The flashing
display shows the current printer baud rate setting. The available baud rates are:
1200, 2400, 4800, 9600, 19200, 38400, 57600 and 115200. Use the LOCAL/TOTAL
button or the ZERO button to toggle through the available rates. When the desired
printer baud rate setting is shown, press the PRINT/ACCUMULATE button.
10.The display will show "". Press the PRINT/ACCUMULATE button. The current
unit of measure (lb or kg) icon will flash in the upper left corner of the display. The
Measurement Units function will set the scale to measure in pounds (lb) or kilograms
(kg). Use the LOCAL/TOTAL button or the ZERO button to toggle between the two
settings. When the desired setting is flashing, press the PRINT/ACCUMULATE
button.
11.The display will show the message "". Press the PRINT/ACCUMULATE
button. The flashing display shows the current Protocol setting. There are four
protocol settings available to choose from; Standard (""), Low Power
(""), Current Loop (".") and "".The Standard setting is the legacy
setting for use in wireless and wired scale networks. The maximum number of
scales that may be connected in a network is 32. The Low Power setting will
significantly improve the wireless battery life for all "non-host" scales. The Current
Loop setting is not used in the CW250. When scales are not part of a totalizing
network, battery life will be improved if "" is selected. Use the LOCAL/TOTAL
button or the ZERO button to cycle through the settings. When the desired protocol
setting is flashing, press the PRINT/ ACCUMULATE button.
12.The display will show ".". Press the PRINT/ACCUMULATE button. The display
will show the current Interface Baud Rate setting in flashing mode. Two baud rate
settings available; 9600 and 115200. Use the LOCAL/TOTAL button or the ZERO
button to toggle between the settings. When the desired baud rate setting is
flashing, press the PRINT/ ACCUMULATE button.
