Introduction
Thank you for purchasing a Doran Scales product. Please read this manual to ensure
obtaining all the benefits that this indicator can provide. If any questions arise, please
contact the Doran Scales Technical Support Department at 630-879-1288.
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 indicator
•DO NOT immerse the indicator
•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

Scale Function
~
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.
Center of zero indicator. The annunciator will illuminate while the scale is
displaying a zero weight.
NET
Indicates a net weight is displayed. Net weight is displayed when a tare
value is present.
lb / kg
Indicates current unit of measure
TOTAL
Lit when accumulator function is active. F1.10 parameter controls the
current function. Checkweighing is the default function.

4
Under, Accept and Over in checkweigh mode. F1.10 parameter controls
the current function. Checkweighing is the default function.

Indicates the accumulation function is active
Battery indicator
Power Up
Connect the cord to a compatible power source. Briefly press PRINT (On/Off) until the
scale beeps.
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 display. 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. ZERO will not function in the
net mode.
UNITS
UNITS selects the current unit of measure. Press UNITS to change the current unit. Lb
and kg are available.
PRINT
PRINT transmits weight data to a printer or other external devices.
GROSS
When in net weighing mode, press to return to gross mode and clear the tare value.
TARE
Press to tare the current displayed weight. The indicator enters net mode. Note that
tare only functions with positive weights. When in net mode, the ZERO function is not
functional.

5
TOTAL (Accumulator)
The TOTAL annunciator is lit when the accumulation function is active. The accumulator
will track the number of weights and total amount of weight on the scale. Do not change
units during an accumulation process.
Accumulate
1. Place item on the scale
2. Press TOTAL to accumulate current weight
3. Add--- is displayed while saving to memory
4. Remove item from scale
5. Weight must return to zero before the next weight can be added to the
accumulated total.
Display Accumulator
1. Press and hold TOTAL until total is displayed
2. Cn is displayed showing the current count
3. Press GROSS to display the total accumulated weight
4. Press PRINT to exit to weighing
Clear Accumulator
1. Press and hold TOTAL until total is displayed
2. Cn is displayed showing the current count
3. Press GROSS to display the total accumulated weight
4. Press ZERO to clear the accumulator
5. Press PRINT to exit to weighing
COUNT (Piece Counting Function)
Press COUNT to switch between weight and count display. When displaying piece
count, a nis displayed in the leftmost digit. Parameter F2.4 controls the method of
piece count entry. F2.4 = 0 will use platform weight to calculate piece weight. F2.4 = 1
will use manual piece weight entry.
Set piece weight with platform weight (F2.4 = 0)
1. Place the container on the scale
2. Press ZERO
3. Place the piece sample into the container
4. Press and hold COUNT until SANPLE is displayed
5. Press PRINT
6. Enter the number of pieces on the scale
7. Press PRINT
8. Piece count is displayed

6
Set piece weight with manual weight entry (F2.4 = 1)
1. Place the container on the scale
2. Press ZERO
3. Place the piece sample into the container
4. Press and hold COUNT until SANPLE is displayed
5. Press PRINT
6. Enter the number of pieces on the scale (UNITS and GROSS select digit, TARE
and ZERO increment and decrement digit value)
7. Press PRINT
8. Input the total weight of the sample
9. Press PRINT
Checkwieghing Function
For checkweighing set the F2.1 to the lowest weight where the checkweigh
annunciators will be active.
Set F2.2 to the Under limit
Set F2.3 to the Over limit
Any weight between the Under and Over limit will activate the OK annunciator
Operation Error Codes
【 】
Invalid operation
【 】
Overload condition: The weight on the platform is greater than scale
capacity.
【 】
Underload condition: The weight is under the calibration zero.
【 】
Zero is above the allowed range (F1.8)
【 】
Zero is below the allowed range (F1.8)

Battery Operation
The indicator will run continuously for up to 38 hours with four 350 ohm load cells. To
maximize battery life, set the Automatic Shutoff Timer (F3.5) which will automatically
powers down the scale after a period of non-use.
Power Off
1) Manual - Press and hold the PRINT push button until the display turns off.
2) Automatic - At the end of the Automatic Shutoff Timer (F3.5) scale parameter setting.
Low Battery
The battery annunciator indicates that the battery is in need of recharging. Once it
indicates no remaining bars, there will be approximately one hour of battery life
remaining before the scale turns off.
Recharging Battery
To charge the battery, plug the wall mount transformer into a wall outlet. While the scale
is charging, light on the wall mount transformer is red. When completed charging, the
wall mount transformer light is green. The battery will fully charge in approximately eight
hours. 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 supports up to 1000 recharges before requiring replacement.

Troubleshooting
If any problem persists, contact Doran Tech Support at 630-879-1288.
Problem
What to Do or Check
Weight reading will not
repeat or does not return to
zero when weight is
removed
Examine the weighing platform for any interferences. Be
sure that nothing is inside the platform, under the load cell
or the weigh bridge structure
Scale overloads before
reaching full capacity
Make sure all four corner overload stops are properly set, if
present. Take the platter off the scale, invert it and place it
on the platform. With 1/2 of the scale's capacity in test
weights concentrated over a corner of the platform, there
should be approximately 1/32" of clearance between the
stop and the bottom of the spider. Check all four corners
then recalibrate the scale.
Scale will not indicate full
capacity or go into overload
Make sure that there is nothing caught in the scale under
or around the load cell or spider, which would interfere with
their movement. If not, check the overload stops using the
above procedure.
Scale will not zero when the
ZERO button is pressed
Make sure that the scale is stable ( annunciator is
off) when ZERO is pressed.
Weight readings don't seem
to be correct
Check the scale's accuracy with a test weight.
Recalibrate if necessary.
Scale drifts off of zero
Check for air currents and/or vibration around the scale.
If that is the cause, it may be necessary to set the F1.6
parameter to a wider setting to compensate
Scale reading is bouncing
Check for air currents and/or vibration around the scale.
If that is the cause, it may be necessary to change the
Display Filter parameter.
Error Message
What to Do or Check
【 】
【 】
Unable to start up. Perform zero calibration (F1.4).
【 】
Eeprom Checksum error. Perform a factory default
(F1.11) and recalibrate scale. If this occurs again, return
to factory for repair.
【 】
The scale is in continuous motion. Check platform for
interference. The load cell may need to be replaced.
【 】
Date / Time data format entry error. Verify correct format
(F3.1) and enter again.
【 】
A/D initialization error. Return to factory for repair.
