Section 1. Unpacking and Installation
Unpacking
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 may 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 drop objects on the scale.
Carefully remove the scale from the shipping carton. Be sure to retain
all shipping materials in case the scale must be shipped elsewhere.
Installation
Place the scale on a stable flat surface. Verify that the bubble level
located under the platter shows that the scale is level. Adjust the four
feet to obtain a level condition (bubble in center.)
Electrical Connections
The DS100 uses a wall mounted transformer to provide power to the
scale. The transformer requires 115 VAC, 50/60 Hz power. Be sure the
AC power is not excessively noisy – this can occur if large inductive
loads, such as solenoids or motors, are on the same power line.
Subjecting electronics to problematic AC power lines may result in
damage not covered by the warranty. Also be sure that the power outlet
and transformer are not exposed to water while the scale is plugged in.
Care & Cleaning
With reasonable care, this product will last for many years. Here are
some tips to care for your DS100 Scale Indicator.
• Hand clean with a damp cloth using mild detergent.
• Do not use strong solvents or abrasive cleaners as this can damage
the touch panel or other plastic parts.
• Do not drop or overload the scale.
• Do not use sharp objects to press any of the buttons.
• Do not immerse.

Section 2. Scale Operation
Fig. 1 DS100 Front Panel
Display Functions
The Model DS100 controls consist of GROSS/NET, TARE, ZERO (ON/OFF),
UNITS and PRINT buttons located under to the LED display. The display is used
to provide weight indications and operator messages describing scale operation.
Power
The DS100 is powered by an AC wall transformer. Turn the scale off by pressing
and holding the ZERO (ON/OFF) button for three seconds. Turn the scale on by
pressing the ZERO (ON/OFF) button.
Units Select
Press the UNITS button to change weight display units from lb, lb:oz, oz, kg, g.
The units annunciator to the right of the LED display will indicate the current
weight.
Print
To transmit the selected print string through the standard RS-232 port, press
PRINT. This will cause the selected print string to be printed. The scale will not
transmit while the scale is in motion. If the scale is in motion when the PRINT
button is pressed, the DS100 will transmit the selected print string once the scale
becomes stable.
Motion
Motion is indicated by the MOT annunciator to the left of the LED display.

Zero Weighing
1. Empty the scale base or place an empty container on the base and press
ZERO to zero the scale. If the scale is in motion when the ZERO button is
pressed, the DS100 will zero the scale once the scale becomes stable.
2. Place an item on the scale and wait for the MOTION indicator to go out
3. Read the weight on the display
4. Press ZERO again to weigh additional items
Net / Gross Mode
The NET annunciator to the left of the LED display will indicate the NET or
GROSS weigh status of the indicator. The indicator enters the NET mode when
the TARE button is pressed with an item on the base. Alternatively, to enter the
NET mode, press the GROSS/NET button. The NET mode is not available when
a TARE weight is not active.
To clear an active TARE weight:
1. If the scale is in the NET mode, enter the GROSS mode by pressing ZERO.
2. When the scale display reads zero in the GROSS mode, press TARE.
Net / Gross Weighing
1. Empty the scale base or place an empty container on the base and press
TARE
2. The indicator will read zero and place the scale in NET mode
3. Place an item on the scale platter and wait for the MOTION indicator to go out
4. Read the weight on the display
5. Press TARE again to weigh additional items
6. Press ZERO, then TARE to clear the tare weight

Section 3. Power and RS-232
Fig. 2 DS100 Rear Panel
Power connections
The DS100 is powered from a wall mounted transformer. The transformer has a
power cord which plugs into the power jack located on the back of the scale. A
strain relief is provided to the left of the power jack. The power cord can be
looped around the strain relief to prevent accidental unplugging.
RS-232 Connections
The DS100 has a standard RS-232 output. To use this feature, the optional RS-
232 cable (P/N DSOPT001 or DSOPT002) is required. To access the RS-232
terminals at the rear of the scale, remove the rear panel from the indicator as
shown in Figure 2.
Insert the cable conductors by placing a small flat blade screw driver into the
terminal slot and then push the handle of the screw driver upwards towards the
top of the indicator. This forces the terminal below to open. Insert the conductor
into the terminal and remove the screwdriver.

Section 4. Data Communications
Introduction to data communications
Basic understanding of serial data communications is needed when setting up the
DS100 to communicate with a printer or PC.
When setting up a serial communications system, there are two concerns which
affect the configuration of that system. These are:
• Baud Rate
• Data Bits and Parity
The baud rate determines how fast the data is sent from the scale. The sending
and receiving units must be set to the same baud settings. Typical values are
1200, 2400, 4800 and 9600.
The DS100 is factory set for eight bits, no parity and one stop bit also known as
8n1. The receiving units must be set to 8n1 for proper communications.
See the technical manual for UPS print string configuration.

The dual print mode provides the DS100 with the ability to print the current
scale reading followed by the equivalent value in kilograms.
The weight is first printed using the “F0” format. Then the weight is
recalculated in kilograms and is sent as a second line of text. The kilogram
data follows the “F0” data format except where parentheses are placed after
the STX character and before the carriage return & line feed.

Section 6. Troubleshooting
General Problem Resolution
Problem What to Do or Check
Weight reading will not repeat or
scale does not return to zero when
weight is removed.
Make sure that the scale platter is not
rubbing or touching the scale cover. Verify
that there is nothing caught in the platform,
under or around the load cell.
Scale overloads early Verify scale calibration is correct. If
problem persists, recalibrate the scale.
Scale will not come to zero when the
ZERO button is pressed.
Make sure that the scale is becoming
stable (Motion annunciator is off). After
pressing the ZERO button, the scale
should zero as soon as it becomes stable.
If problem persists, there may be a
problem with the touch panel or
motherboard.
Weight readings don’t seem to be
correct.
Verify the scale calibration with an
accurate test weight. If the readings are
not correct, recalibrate.
Scale drifts off zero. Check for air currents and/or vibration
around the scale. If that is the cause, it
may be necessary to set the Z ATand nnA
parameters to wider settings to
compensate (see the parameter section.)
Verify that no mechanical restrictions exist,
i.e. platter rubbing, something caught
under or around the load cell.
Scale shuts itself off or will not turn
on.
Press the ZERO button to turn on the
indicator.
The transformer may be bad or the power
connector at the rear of the scale may
have an intermittent connection. Check
the power connector at the rear of the
scale.
