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 DMC-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 380 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.

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 380 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

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

WEIGHT, DENOMINATION, and VALUE 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 or in

the container on the platform(s) and it exceeds the scale start

range, the display will show the error message OF indicating “weight overflow.”

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.

FRONT OF SCALE

The DMC-782 scale is a high-precision instrument. Although the scale needs very little maintenance, you may
want to check the calibration after every month or so of normal usage. To do this you it is preferable to have a test
weight of approximately the total capacity of the scale (i.e. a 10 lb weight if you have a 10 lb capacity scale). If
the reference weight is not equal to the full capacity of the scale, it must at least be greater than 10% of the full
scale capacity. For instructions on how to calibrate the DMC-782 using a test weight equal to the full capacity of
the scale, see Section 4.1 below. If you are calibrating the scale using a te

24 DMC-782 Operation Manual

6.0 Scale Programming

The DMC-782 can store information for the coins, tokens, and other items you count most frequently,
eliminating the need for re-entering data during coin counting. With each coin, token or item you can specify a
Value, Tare Weight, and Unit Weight. Up to 23 items can be programmed into your DMC-782 coin counting
scale, with as many as 9 of those being able to be assigned to the preset keys (F13 to F23).

6.1 Standard Weights for Coins and Dollar Bills

Table 6-2 below lists the standard weights programmed to the DMC-782’s preset keys at the factory..

Coins Standard Unit Weight

1 cent coin (penny) 5.94 unit weight/1000

5 cent coin (nickel) 11.032 unit weight/1000

10 cent coin (dime) 5.013 unit weight/1000

25 cent coin (quarter) 12.419 unit weight/1000

50 cent coin (half-dollar) 24.72 unit weight/1000

silver dollar 49.44 unit weight/1000

Susan B. Anthony dollars 17.940 unit weight/1000

Sacagawea dollar coins 17.684 unit weight/1000

Table 6-1. Standard Coin and Dollar Weights

Since coin and bill weights vary depending on the age, condition, and wear of the actual items being counted, it
is recommended that you periodically recalibrate the coin unit weights using samples from the actual money
being counted. The larger the sample, the more accurate the coin unit weights will be. Samples of 500 to 1000
coins produce very accurate coin unit weights using the procedure described in Section 6.2 below.

6.2 Program a Value and Unit Weight Where the Unit Weight is Known

The DMC-782 has the capacity to store information on up to 25 items (9 of which can be assigned to the preset
keys F15 to F23). This section details the procedure for storing the value, tare weight, and unit weight to be
associated with a coin, token or item. You can enter all of this information for each item or only the data pertinent
to your application. The memory fields associated with item codes can be programmed subject to the following
parameters:

• If the sample size is 10 pieces, press the PCS key to compute the unit weight. If the sample is made

up of more or fewer than 10 pieces, enter the number of coins or tokens in the sample from the
numeric keypad and then press the PCS key.

• If the sample size is large enough to calculate an accurate unit weight, that unit weight will be

displayed in the Value display and the number of coins on the platform in the Amount display. Skip
to Step 7 below to save the data and exit from the Programming Mode.

If the DMC-782 software detects that the sample size is insufficient to accurately calculate a unit
weight for this coin or token, the scale will request that you increase the sample size as described in
Step 6 below.

6. If the sample pieces were not sufficient to accurately calculate a unit weight, place exactly 10 more
pieces of the same coin or token on the platform or in the container on the platform and press the PCS
key to compute the unit weight.

The accuracy of the unit weight can be made increased by adding a much larger sample of the coin or
token. Add more pieces to the sample and press the PCS key to have the scale recompute the unit
weight.

7. Press the * CONFIRM key to save the data, then press the SHIFT key to exit the Programming Mode
and return to the Weighing Mode.

6.4 Program a Preset Tare Weight to a Key

1. Enter 121 while holding the REZERO key to enter the Programming Mode. The display will show ProG.

2. Press the RECALL TARE button. The display will show Pt to indicate that you are programming a
preset tare.

3. Press the preset key that you want to program the tare to. The preset key will appear on the display to
confirm. If there is a tare value currently programmed to the key, it will also be displayed.

4. Enter the value of the tare to be programmed. If less than one pound, enter a leading zero, followed by
the decimal point and the value. (Example: A tare of 1/2 pound should be entered as 0.5.)

5. Press the * CONFIRM key in order to save the data or press the CLEAR key to clear the data if you have
entered it incorrectly and want to reenter it. Pt will appear on the display. To exit the Programming Mode
without recording any data, press the SHIFT key.

6. To enter another preset tare, press another preset key on the keypad and repeat steps 3 to 5.

6.5 Delete Preset Coin Data from Memory

The DMC-782 allows you to delete preset coin data from memory if you no longer need the data or want to
reprogram the key for another item. The following procedure describes the steps used to delete a single specific
set of coin data (tare weight, unit weight, and value).

1. Enter 363 while depressing the REZE

ProG.

2. Press the preset key number for the coin data that
display for you to confirm that it is the correct key and the preprogrammed value will appear in the Value
display.
