INTRODUCTION

The 3255 Checkweigher series scales are versatile and easy to use. The large display is allows
you to easily view the weight.

The 3255 allows you to store 10 preset checkweighing target settings, provides a simple counting
feature and is battery operated using 6 “C” cell alkaline batteries (not included).

The 3255 Checkweigher series is NTEP approved at specific capacities and resolutions.

The stainless steel weighing platform and base allows you to wipe down the unit in moist
applications. Please note this unit is not intended to be used in wash down applications. Please
contact your local dealer to to see if your application meets the requirements of this scale.

The 3255 is equipped with a foldable display bracket, which allows you to lower to display
assembly when you are using the unit in portable applications.

GETTING STARTED

1. Remove the scale from it’s packaging. Included is the 120 Volt AC adapter, user manual, scale
base and display assembly.

2. To install the scale raise the display assembly up from the base, adjust the display locking
button into place and make sure the display head is locked into position.

3. To ensure proper weighing make sure the scale is level, using the level bubble on the rear of the
unit. Once level, tighten locking nuts using a 13 mm wrench.

4. Always fit the Adaptor to the scale BEFORE connecting to an electrical outlet. Disconnect from
the electrical outlet BEFORE disconnecting the adaptor from the scale.

5. If installing “C” batteries make sure you do not use the AC adapter.

BATTERY INSTALLATION

*** WARNING ***

1. Remove Battery Cover Screws. 2. Insert 6 “C” cell Alkaline batteries into
compartment, and replace cover.

When using the C3255 as a battery operated scale, do not use the AC adapter!

LOW BATTERY POWER

The 3255 battery life is estimated at 250 hours of continuous use. To conserve battery life, make
sure you have configured the scale for Auto Shutdown, see configuration section.

1. (Low battery indication) will display on LCD display when battery’s power is insufficient to
power the scale.

2. When is displayed, remove old batteries and plug in the AC adapter or replace with new
batteries.

COUNTING PROCEDURE

The C3255 check weigher includes a simple counting function. The minimum sample size weight
required is 1/5d of scales capacity and resolution.

*Important note, for accurate counting it is suggested to use the largest sample weight as possible.

1. Make sure all weight is removed from platform.

2. If tare is required, press the Tare key prior to sampling to tare out the weight of a empty

container.

3. Press MODE key to enter into counting mode, the display will show:

4. There are four pre-defined samples sizes available in the C3255. They are 10 pieces, 25 pieces,

50 pieces and 100 pieces. Press SET key to scroll to the desired sampling quantity.

5. Once the desired sampling size is chosen, add the appropriate # of pieces onto the platform or

into the empty (tared) container.

* NOTE: If no weight is placed on the scale, and you exit the counting function by pressing the
MODE key, the scale will display an invalid # of pieces.

6. With the sample weight on the scale, the display will flash for 3-5 seconds.

7. Once the sample weight is stable, the stable enunciator will light and the scale will show the

value of the sample weight.

•

• NOTE: If the displayed value of pieces does not equal the sample chosen, repeat steps 1-7

••

and chose a higher sample size value.

8. Press the MODE key to exit counting and return to normal weighing mode. Your sample value

will be saved and stored until you store a new sample size is stored.

NOTE: The counting feature on the Model C3255 is NON TYPE approved.

STORING CHECK WEIGHING TARGET SETTINGS

The C3255 allows you to store up to 10 target settings, using numbers 1-10. The keyboard is used
to enter in you upper and lower check weight limits. Prior to setting up your target settings, use the
mode key to scroll to the correct units of measure.

1. In normal weighing mode, press numerical key, and then press SET key to enter into a check
weighing setup mode. The display will show as below:

2. Using the numeric keypad, enter in the desired lower check weight, and press SET key. The
display will show as below:

3. Using the numeric keypad, enter in desired upper check weight, and press SET key. The
check weighing setup process is finished.

The display will briefly flash the lower and upper limits for you to make sure the setting were stored
correctly. The scale will now exit from the set-up mode and return to normal check weighing mode.

“03” Indicates you have stored a check weighing limits for key 3.

4. To set up additional check weight target setting, repeat steps 1-3.

5. To exit check weighing mode, press the MODE key to exit and return to normal weighing mode.

* Note: If you do not enter a check weight limit within 10 seconds the scale will exit target settings
and return to normal weighing mode.

If the upper limit is lower than the lower limit, the buzzer will beep-beep-beep to remind the
operator the setup is incorrect. The device will auto clear the upper check weight and return to the
last step – upper check weight setup.

USING STORED CHECK WEIGHING TARGET SETTINGS

The Check weighing function can be used both in normal weighing mode and counting mode.
Under normal mode, it stands for weight. While in counting mode, it stands for quantity.

To use a stored check weighing target setting:

1. In normal weighing mode, press the desired numeric key and then press CALL key to enter into

check weighing mode. The scale will briefly show upper and lower check weights, for you to
validate the correct key has been chosen and activate the check weighing function. The following
is displayed if you press the 3 key, then CALL.

2. Load weight on platform.

3. If loaded weight is in the setting weighing range, LCD will show and the buzzer will
continually beep until the item is removed from the platform

.

4. If loaded weight under lower limit, LCD will show to remind the operator the loaded
weight is not within the setting range. The low bar graph segment will change to indicate how
close you are to achieving the acceptable weight.

5. If loaded weight over upper limit, LCD will show to remind the operator the loaded
weight is not within the setting range. The high bar graph segment will change to indicate how
close you are to achieving the acceptable weight.

To exit the check weighing mode, please press 0 key and then press CALL key or press the

MODE key.
Note:

Under check weighing mode, press CALL key to call out the existed upper and lower check limit.

CALIBRATION PROCEDURE – NON- SEALED

There are two methods of calibrating the scale. Non –sealed, when the TrAd configuration is set
to off and Sealed, when the TrAd configuration setting is to on. These instructions help you
calibrate the scale, when it is in the non-sealed mode.

Periodically your scale may require calibration to ensure proper weighing. You will need a pre­calibrated or accurate weight to calibrate the scale. If calibration is performed with a weight other
than a pre-calibrated or accurate weight, it will cause your scale to weigh inaccurately. Scale
calibration is accomplished, when needed, by the following instructions

FUNCTION SCALE RESPONSE

1. Remove all weight from the platform, and
make sure the scale is in a level and stable
environment.

2. Press and hold the SET key for three
seconds to enter into the configuration mode.

Scale displays “Mode”

3. Press the CALL key 4 times to “CAL_U”,
press the Set key. The “CAL_U” function
allows you to set the capacity of the calibration
weight .

Scale displays “FULL”.

4. Press the CALL key to scroll through to
choose 1 / 2 and 1 / 4. See Table 3 for valid calibration

weights required

5. Once you have selected the calibration
weight, press the SET key once.

Scale displays “CAL_U”.

6. Press the CALL key once

Scale displays “CAL_u”.

The “CAL_u” configuration setting allows you to configure the scale to calibrate in pounds or
kilograms.

7. Press the SET key once

Scale displays “lb”

8. Press the CALL key to scroll through to
choose lb and kg. Once you have selected
the calibration weight, press the SET key once.

Scale displays “CAL_u”.

9. Press the CALL key once to scroll to
“Count”. Press the SET key once.

Scale displays “ XXXXXX” (Raw counts
