Introduction
Thank you for purchasing a Doran Scales product. Please read this manual to ensure
obtaining all the benefits that the indicator can provide. This manual is intended for
revision 5.3 and greater scales. If required, Doran can upgrade the software in your
scale to the current revision. Please contact the Doran Scales Technical Support
Department at [email protected] for upgrade details.
Unpacking Your Scale
Before unpacking your Doran scale, please read the instructions in this section. Your
new scale is a durable industrial product, but it is also a sensitive weighing instrument.
Normal care should be taken when handling and using this product. Improper handling
or abuse can damage the scale and result in costly repairs that will not be covered by
the warranty. If you notice any shipping damage, notify the shipper immediately. Please
observe the following precautions to insure years of trouble-free service from your new
scale.
• DO NOT drop the scale.
• DO NOT immerse the scale.
• DO NOT drop objects on the platform.
• DO NOT pick up the scale by the top of the weighing platform.
• Carefully remove the scale from the shipping carton.

Fig. 1: Model 4300 Front Panel Layout
The operational controls for the Model 4300 consist of the ZERO, PRINT, UNITS, OVER
and UNDER buttons. A six digit LED display is used to display weight and operator
messages during scale operation. Three lights, above the LED display indicate
checkweighing status. Scale status is displayed on annunciators located to the left of
the display area. Weight units are displayed on four annunciators located to the right of
the display.
Scale Annunciators
Unit of measure lb, oz, kg, g or lb:oz. The units annunciator to the right of
the display will indicate the current unit of measure.
Battery option status indicator. When the annunciator illuminates, the
battery charge is low and the scale should be plugged in to recharge the
battery. While the scale is charging, the battery annunciator will flash.
When the charging is complete, the annunciator will turn off.
Center of zero. The annunciator will illuminate while the scale is displaying
a zero weight.
4
Motion indicator. This symbol represents motion or instability of the
weight. The annunciator will illuminate when motion is sensed on the
platform. Changes in weight, vibration or air currents can cause the scale
to go into motion.
Under illuminates to indicate weight is below the Under target and above
the Low target or flashes if below the Low target.
Accept illuminates to indicate weight is at or above the Under target and at
or below the Over target.
Over illuminates to indicate weight is above the Over target and below the
High target or flashes if above the High target.
Power Up
Connect the cord to a compatible power source.
For indicators with battery option, press and hold ZERO.
Basic Weighing Operation
1) Remove all items from the scale platform
2) Press the ZERO button to zero the scale
3) The weight display now reads zero
4) Place an item on the scale platform and wait for the motion annunciator to turn
off, indicating an accurate, stable weight
ZERO
ZERO is used to zero the scale. To zero the scale, wait until the scale is stable and
press the ZERO button. The scale will not zero if the scale is in motion. The zero
function will operate over the entire capacity of the scale.
The scale is equipped with a Zero on Demand parameter which zeros the scale upon
the next stable reading after ZERO is pressed.
UNITS
UNITS selects the current unit of measure. Press UNITS to change the current unit.
The units annunciator to the right of the display will indicate the current unit or measure:
lb, oz, kg, g or lb:oz.
Each unit can be enabled or disabled in the scale parameter setup. Lb:oz is disabled by
default. Lb:oz not available for tolerance values and cannot be transmitted as data.
PRINT
PRINT transmits data to a printer or other external devices. When the data is
transmitted, the leftmost display digit will momentarily display an "r" to confirm data
transmission.
5
There are many parameters that customize the control of manual and automatic
transmission of data. Data can be transmitted via standard RS232, Ethernet, WiFi,
Bluetooth or USB. Contact Doran Tech Support at [email protected] for support.
OVER
OVER allows entry of the upper checkweighing limits. It is also used to increment a
checkweighing value that is being modified.
UNDER
UNDER allows entry of the lower checkweighing limits. It is also used to decrement a
checkweighing value that is being modified.
6
Battery Operation
The 4300 can be optionally configured with a self-contained Rechargeable Sealed
Lead-Acid battery and charging circuit, both internal. The scale is designed to run
continuously for up to 60 hours with a single 350 ohm load cell. To maximize battery
life, leave the auto-off timer enabled which will automatically power down the scale after
a period of non-use.
Power Off
1) Manual - Press and hold the ZERO push button until the display turns off. The scale
will not turn off if plugged in but will instead display “rel pb”.
2) Automatic - At the end of the Unit On Timer (
tdy
) scale parameter setting. The scale
will not turn off if plugged in.
Low Battery Indication
The battery annunciator indicates that the battery is in need of
recharging. Once it turns on, there will be approximately one hour of
battery life remaining before the scale turns off. Multiple load cells,
USB, Bluetooth, Ethernet, 4-20mA and WiFi communications will
reduce battery life.
Recharging Battery
To charge the battery, plug the line cord into a wall outlet. While the scale is charging,
the battery annunciator will flash. The charging circuit will fully charge the battery in
approximately eight hours. When the charging is complete, the annunciator will turn off.
The scale can be used while recharging the battery.
Leaving the scale plugged in will ensure a fully charged battery and will not affect the life
of the battery. The battery is able to support up to 1000 recharges. This is an estimate
as many factors can affect battery life, including severe temperature changes and
charging before the scale displays low battery.

Three Band Checkweighing
Three band checkweighing classifies weighments into over, accept and under. The
default configuration is three band checkweighing. Note that lb:oz is not supported for
checkweighing limits.
Three Band Checkweighing (
9.1 C.o.
set to operation starting with
3
)
1. Remove all items from the scale platform
2. Press ZERO and the display will read zero weight
3. Place an item on the scale platform and wait for the scale to stabilize
4. Accept, Over or Under annunciators indicate checkweigh status
Enter and Display of Checkweigh Limits (
9.2 C.E.
default value
SCr
)
1. Press OVER or UNDER
2. The display will briefly read over or under followed by the current limit
3. Press either OVER to increase the weight value or press UNDER to decrease the
weight value. Pressing and holding will accelerate the weight scroll.
4. Press ZERO to save the value or press PRINT to exit without saving
5. saVed is displayed if saved or abort is shown if aborted
NOTE: To digitally adjust the platform weight for OVER and UNDER limits, the
parameter C.E. must be set to SCS.
Weight Reference and Digital Entry of Checkweigh Limits (
9.2 C.E.
set to
SCS
)
1. Press ZERO
2. Place a target item on the scale
3. Press OVER or UNDER
4. The display will briefly read over or under followed by the weight on the platform
5. Press either OVER to increase the weight value or press UNDER to decrease the
weight value. Pressing and holding will accelerate the weight scroll.
6. Press ZERO to save the value or press PRINT to exit without saving
7. saVed is displayed if saved or abort is shown if aborted
NOTE: To digitally adjust the platform weight for OVER and UNDER limits, the
parameter C.E. must be set to SCS.
Weight Reference Entry of Checkweigh Limits (
9.2 C.E.
set to
Pb
)
1. Press ZERO
2. Place a weight equal to the desired OVER or UNDER limit on the platform
3. Press OVER or UNDER
4. over or under is displayed and then saVed to indicate the new OVER limit was
saved.
NOTE: To enable Push-button entry of OVER and UNDER limits, the C.E. parameter
must be set to pb.
