The DC-782 is a low cost counting scale that offers practical solutions for a full range of counting applications.
Its counting resolution of 1/500,000 gives you maximum counting precision and accuracy. Its backlit LCD
display enables operators to easily see weights and quantities. The DC-782 can also store an item code, tare
weight, unit weight, and setpoint value for 25 of your pieces, parts, or items and recall 10 of them with the
pressing of a single preprogrammed key. The RS-232 output allows you to transmit data from the scale to a PC.
When portability is required, choose the battery operation option of the DC-782 for over 300 hours of continuous
use in mobile workstations, outdoor applications, and rental fleets. The DC-782 is rugged enough to operate
reliably in many environments and withstand transport from one area of the plant to another or from one business
to the next.
1.1 Capacities and Resolutions
Table 1-1 lists the scale capacities, minimum graduations, and tare ranges for all models of the DC-782 counting
scales. The display resolution is 1/6,000 with an internal or counting resolution of 1/500,000.
1.2 Modes of Operation
The DC-782 has three modes of operation:
• Weighing Mode – where all weighing, counting and outputting of data operations take place.
• Programming Mode – where item data can be programmed into the memory of the scale. The display

2.4 Powering Up the DC-782
The DC-782 can be operated either from an AC power source or with a rechargeable battery pack (DC power).
The DC power allows the unit to be completely portable. Instructions for DC operation are contained in
Section 2.4.2.
2.4.1 AC Power Source
NOTE: Production units manufactured after February 2011 have a standard power cord.
To power up the DC-782 using the AC power cord:
1. Connect the AC power cord under the scale base as shown in Figure 2-2.
Figure 2-2. AC Plug-in Location on Underside of DC-782
2. Plug the AC power cord into a grounded 115 VAC receptacle.
3. Press the ON/OFF key located on the front of the scale. The scale will run through a check of the LCD
display’s segments. How thorough the segment check is depends on the setting of SPEC 20, Bit 2. The
default is 0: Fast (For further instructions on how to set the scale’s specifications, see Section 3.2.1):
• If SPEC 20, Bit 2 is set to 0: Fast, the scale display’s 888’s for 1.5 seconds, then blanks for 1.5
seconds. It then displays 888’s again followed by a blank display for another 1.5 seconds before
going into the normal weighing mode.
• If SPEC 20, Bit 2 is set to 1: Standard, the scale’s display will test the LCD segments for each
numeral from 0 to 9, asterisks, decimal points and annunciators before going into the normal
weighing mode.

4. Once the scale is on, the time interval before the scale will automatically power itself off, if there no key
is pressed and no weight is placed on the platter, is determined by SPEC 00- Auto Power-Off Function.
The default is 0000: Disabled. (For further instructions on how to set the scale’s specifications, see
Section 3.2.1)
2.4.2 DC Battery Pack Replacement/Installation
An optional DC battery pack (PN 108516) for the DC-782 is available and can be purchased from RLWS to ship
with the scale or retrofit in the field. The rechargeable 6V 5.0 AH battery pack allows for up to 300 hours of
scale use without an AC power supply (with the backlight off). It is located in the bottom of the scale base. Use
the following procedure to install or replace the battery pack.
1. Unplug the scale from power source.
2. Place scale its left side.
Do not turn the scale upside down. Always work with the scale on its side. Damage to the load cell can
occur if the scale is turned upside down.
3. Unscrew the thumb screw (4 below) holding the battery compartment door (5 below) closed.
4. Unscrew the two screws (3 below) holding on the battery holding bracket (2 below) and remove the
bracket.
Figure 2-3. Installing the Battery
5. If you are removing a battery previously installed, remove the battery from its compartment, then
disconnect the black (-) and red (+) electrical leads from the battery (6 above). If you are installing a new
battery, go to step 6.
6. Attach the red lead to the positive (+) terminal of the new DC battery pack, and the black lead to the
negative (-) terminal. Place new DC battery pack in battery compartment.
7. Replace the battery holding bracket (2 above) and fasten it with its two screws (3 above).
8. Replace the battery compartment door (5 above) and fasten it with its thumb screw (4 above).
9. Put the scale back upright on its feet.
10. Press the ON/OFF key located on the front of the scale. The scale will run through a check of the LCD
display’s segments. How thorough the segment check is depends on the setting of SPEC 20, Bit 2. The
default is 0: Fast (For further instructions on how to set the scale’s specifications, see Section 3.2.1):
• If SPEC 20, Bit 2 is set to 0: Fast, the scale display’s 888’s for 1.5 seconds, then blanks for 1.5
seconds. It then displays 888’s again followed by a blank display for another 1.5 seconds before

going into the normal weighing mode.
• If SPEC 20, Bit 2 is set to 1: Standard, the scale’s display will test the LCD segments for each
numeral from 0 to 9, asterisks, decimal points and annunciators before going into the normal
weighing mode.
2.4.3 Battery Charging
A fully charged battery allows for approximately 300 hours of continuous use (with the backlight off). When the
battery is low the battery indicator light will light up. It will take approximately 12-14 hours to fully recharge a
battery that has been completely dissipated. To charge the battery, plug in the AC power cord.
2.4.4 Start-Up Screens
1. If SPEC 20, Bit 3 - Version Display When Power On is set to 0: Allow, the scale will display the current
version of the firmware it is using as it powers up (For further instructions on how to set the
specifications, see Section 3.2.1).
2. After a test of the different elements of the display, the scale takes you to the stand-by screen in the
Weighing Mode. SPEC 20, Bit 2 - Selection of Segment-Check Style controls whether the startup test of
the segments is Fast or Standard. At the stand-by screen the QUANTITY, WEIGHT, and UNIT WEIGHT
displays show zeroes.
From this stand-by screen all of the basic weighing, counting and inventory operations can be performed
3. If there is anything on the platform(s) and it exceeds the scale start range, the display will show the error
message OF indicating “weight overflow”.
Note: The Initial Start Range settings are controlled by SPEC 20, Bit 1. The default setting is 0: ± 10% OF FULL SCALE.
If this error appears, remove the weight from the platform and the scale will continue its startup
sequence.

12 DC-782 Operation Manual
3.0 Configuration Settings
This section presents the setup and configuration of the DC-782 counting scale to be used specifically by
distributors and service technicians. Configuring these specifications allow you to tailor the DC-782 to your
specific applications.
Setting the specifications allows you to modify the functionality of the DC-782. Use the tables in this section to
view the options you can modify.
3.1 Putting the Scale in Maintenance Mode
Before you can configure the specification settings of the DC-782 scale, you must first place the scale in
Maintenance Mode by pressing the span switch.
NOTE: You can exit the Maintenance Mode and return to the Weighing Mode at any time by pressing the TARE key.
Turn the scale on, then press the span switch to reset it. (See Figure 3-1 below.)

3.2 Configuring Specification 141 and 142 Settings from the Scale Keyboard
The following tables list the DC-782 specifications, their corresponding default values, and the other possible
values to which they can be programmed. The default values are set at the factory when the scale is shipped.
SPEC 0 through SPEC 10 (Table 3-1) are customer specifications and use the 141 access code, while SPEC 20
through SPEC 29 (Table 3-2) are weight and measurement specifications, and use the 142 access code
In programming specifications, the + (Plus) and –(Minus) keys allow you to move to the next or previous
specification. The CLEAR key cancels any input you have made. The * CONFIRM key temporarily stores to
memory any changes you have made. The TARE key saves to memory the changes you have made and returns
you to the weighing mode. Note also that when programming specifications, only the 0 and 1 keys on the
numeric keypad are enabled, since those are the only valid entries.
3.2.1 Customer Specification (141 Settings)
1. To configure customer specifications, press and hold the REZERO key and enter 141 using the numeric
keypad. The first SPEC code is displayed.
The Quantity display shows what specification you are in (in this case, SPEC00). The Weight display
shows how this specification is currently programmed (Bit 3 = 0; Bit 2 = 0; Bit 1 = 0, and Bit 0 = 1 in this
example, while the Unit Weight display will show any changes you enter.

If this is the SPEC that you want to modify, enter the new setting from the numeric keypad and press the
* CONFIRM key to enter the change into temporary memory and move to the next SPEC code.
2. Use the + (plus) and –(minus) keys to scroll through the specifications until you find the one you want.
Then make your changes per the instructions in Step 1. Alternatively, you can go directly to a specific
specification by entering that specification’s number and pressing the # key (Example: 9 + # will bring
up SPEC 09; 11 + # will bring up SPEC 11).
3. To change another SPEC code before exiting, repeat Steps 1 and 2.
4. To save all the changed SPEC settings currently in temporary memory and exit to the Weighing Mode,
press the TARE key.
5. Turn off Power and restart the scale.
