Introduction
The EL-3000 Counting Scale, available in several capacities, is an easy to use, high resolution
counting scale featuring several programmable
weigh modes, multi-item print function, and a
weight accumulator.
Housed in a durable ivory-colored plastic enclosure, the unit displays its numerals on a 5½-digit
LCD type display. A removable 8"x 9" stainless
steel platform allows for easy cleaning when
used to count greasy or dusty items. A plastic
skirt is also included to protect the scale’s outer
enclosure.
The unit can transmit on demand or continuously
in a popular data protocol. A multi-item print
mode is also included for use with a printer.
A 5-key membrane panel contains all of the
scale's functions. A durable 8" x 9" stainless steel
platform allows for accurate piece counting.
A battery power option is available which allows
the unit to operate for approximately 10 hours on
a charge. The scale can then be charged overnight in a period of 8 to 10 hours.
Getting Started
After unpacking the scale, a small amount of assembly is required:
Locate the sub-platform, four (4) Hex screws, and enclosed Allen wrench. Place sub-platform onto
scale's load point with all rubber parts facing up. Install and tighten the four Hex screws.
Plug the enclosed adapter into the scale first, then an AC outlet.
If using the scale with a printer or remote device, plug the connecting serial cable into the DB-9 con-
nector on the back of the scale.
If the optional battery operation was ordered, please charge the battery overnight before using. See
Optional Battery Operation on Page 9 for more information.

Percentage Operation
The EL 3000 Digital Scale contains a percentage operation which is useful for such applications as
filling, check weighing and moisture determination.
The total weight of the item being sampled determines the resolution of the percentage readout. For
example, if the sample weight is greater than or equal to 10,000 external scale divisions, the scale will
discern 0.01% increments. See table below more information.
To use the percentage operation:
1. Toggle the
MODE
key until the scale is in “%” mode. If there is no previous sample entered, the
scale will respond with the following display indication. If the following message does not appear,

Percentage Operation Sample Weight Guide:
The minimum sample weight is 100 scale graduations. This will allow the scale to discern 1 part in 100.
To get a higher resolution, use 1,000 or even 10,000 times the scale’s graduations as your sample
weight. Below are three examples to help determine the best sample weight for your application.

Piece Counting Operation
The EL 3000 Digital Scale uses the
sampling
method to determine the number of pieces on
the platform. The accuracy of this operation
depends upon part consistency and sample
weight. When sampling pieces, always count the
parts in your hand and place them on the
platform all at once.
by applying small quantities of pieces – two to
current piece count – to the platform. For example, if the current piece count shown on the display is 10, then adding 2 to 10 more pieces to
the platform at the same time will trigger AAWI.
When this occurs, the "Unit Wt." indication will
flash briefly.
To further increase the accuracy of this operation, the EL 3000 contains an algorithm called
"Automatic Average Weight Improvement"
(AAWI) which allows updating of the piece count
The total sample weight and the unit piece
weight both have limits to assure accuracy.
These limits can be found in the table at the bottom of the page.

pieces on the platform in succession. If this operation fails even with 500 pieces, the unit weight of
the objects you wish to count is not heavy enough for the scale to process accurately. See table
below for more information.
Piece Count Sample Weight Guide:
The scale has both a minimum piece weight and a minimum sample weight to ensure accuracy. To
obtain the minimum piece weight, multiply the scale’s graduation by 0.8. To obtain the minimum sample
weight, multiply the scale’s graduation by 25. Shown below is an example for a 12 lb scale:
The EL-3000 comes equipped with a handy accumulator function which works in conjunction with all of
the scale's displayable units except Unit Weight. The accumulator uses a memory to store the weight
readings and piece counts. Much like a pocket calculator, this memory can be added to, displayed, and
cleared at any time.
When used with a printer, the EL-3000 prints the weight each time the M+ key is pressed and prints
the accumulated total when the MR key is pressed. See Multi-Item Print on Page 8 for more
information.
To use the accumulator function:
1. Use the

Multi-Item Print
The EL-3000 comes standard with a feature called “Multi-item Print”. This allows the user to have a
printout of each weighment transaction plus the total. To enable this feature, select “1” for A4 in the
User Menu and plug a serial printer into the DB-9 connector on the back of the scale. You may also
need to alter the serial parameters A1 and A2 in order to match the printer’s requirements.
Shown at right is an example of the multi-item
print function. Each weighment is printed when the
Here are a few notes for those users who ordered the Battery Operation option for the EL-3000:
Before using the scale for the first time, please charge the scale overnight.
The scale’s battery should operate for about 10 hours if left on continuously. Therefore, greater
usage times can be achieved by selecting an appropriate Auto Power Off Period under A5 of the
User Menu.
The scale can be charged while ON or OFF and can be operated while charging.
To charge the internal battery:
1. Connect the charger (AC Adapter 15 VDC, 800mA) to the scale , then plug the charger into an AC
outlet.
2. After the charging period expires, unplug the charger from the AC outlet, then from the scale. The
scale is now ready for use under its own battery power. If the scale is not allowed for charge for the
full recommended time period, you may notice a decline in the usage period. This is due to the battery’s reluctance to accept a charge. Therefore, always charge the scale for at least 10 hours before using.
3. The charger may be left connected to the scale indefinitely without damage to the internal battery.
When to charge the internal battery:
1. When the scale needs to be charged, the Low Battery Indicator will appear in the lower right-hand
corner of the display. The scale may be used for an additional 15 to 30 minutes without damage to
the internal battery. If the scale is used for more than 30 minutes after a low battery
indication, permanent damage may occur to the battery and/or the battery may not accept a
charge.
2. With the sealed lead-acid type battery, it is OK to charge the battery at any time to keep the battery
“fresh”. You do not necessarily have to wait for the Low Battery Indication.
When a low battery indication occurs, the scale automatically shuts off after 5 minutes if the

Calibration
The EL-3000 scale may be calibrated with any precision test weight from 10% to 100% of full scale
capacity. If the scale was ordered in a avoirdupois configuration, the test weight unit must be in pounds.
If the scale was ordered in a metric configuration, then the test weight unit must be in kilograms. The
recommended test weight is about 2/3 of the full scale capacity, but in general, the larger the test
weight, the more accurate the scale will be.

Serial Data Formats
Full Duplex Overview:
The EL-3000 is equipped with a full duplex ASCII compatible RS-232C serial communications terminal
wired as a DB-9 type connector mounted on the back of the scale. Full Duplex mode is enabled by selecting “0” for A4 in the User Menu. The data format provides both Continuous and Demand serial
transmission modes, selectable by A3 in the User Menu.
The Continuous mode is used to interface to computers, scoreboards, and other remote devices requiring constant data updating. The transmission occurs at the end of each display update. Primarily designed to interface to printers, the Demand mode allows control from a host device, usually a PC, and
can be activated by pressing the
key on the front panel.
