Introduction

Thank you for purchasing a GC series counting scale. This manual describes how the GC series counting
scale works. For effective use, read this instruction manual thoroughly before using the product.

3.

Overview

This product has the following characteristics.
Counting scales with display resolution 1/6000 to 1/7500.
When counting the number of pieces that have the same weight, the number can be calculated from theweight (unit weight) of one piece.
Unit weight can be set in various ways as follows.
- Weigh the total weight of samples for which quantity is specified such as five, ten, etc.
- Weigh the total weight of samples for which quantity is arbitrary.
- Input a known unit weight with a keyboard.
- Call up the unit weight that is stored in internal memory or external memory (micro SD card).
- Set externally such as with a computer.
Unit weight can be easily set according to the status of LED blinking.
With ACAI (Automatic Counting Accuracy Improvement), counting with accurate unit weight is possible.
In internal memory, unit weight up to 1000, item code, tare weight, total count, and comparator upperand lower limits can be stored together with the ID.
For the item code, upper-case/lower-case alphabet and numeric digits are usable.
The M+ function adds the counting results.
The comparator function compares upper and lower limits that have been set with the counted value or
weighed value. The result is shown as LO, OK, and HI (red, green, and yellow).
The display can be separated from the main scale.
For the power, an AC adapter or commercial mobile battery is usable.
With the RS-232C cable or AD-8561 (Multi-Interface), weighing data and counting data can be sent to acomputer.

Precautions for Use

4.1. Precautions When Installing the Scale
Do not touch the AC adaptor with wet hands. Doing so may cause electric shock.
Do not install the scale in a location where corrosive gas or flammable gas are present.

Do not apply excessive load to the cable.
The scale is heavy. Use caution when lifting, moving and carrying the scale. Do not lift the scale byholding the display unit or weighing pan. Doing so may cause the product to fall and be damaged. Holdthe bottom side of the base unit when lifting, moving and carrying the scale.
Use the scale indoors. If used outdoors, the scale may be subjected to lightning surges that exceed thedischarge capacity. It may not be able to withstand the energy of the lightning and may be damaged.
Consider the following installation conditions in order to obtain the proper performance.
The ideal conditions for installation are stable temperature and humidity, solid and level surface, location
with no draft or vibration, indoors out of direct sunlight and a stable power supply.
Do not install the scale on a soft floor or where there is vibration.
Do not install the scale in location where breezes or large fluctuations in temperature occur.
Avoid locations in direct sunlight.
Do not install in a location with strong magnetic fields or strong radio signals.
Do not install the scale in a location where static electricity is likely to occur. When humidity is 45% R.H. or less,plastic and insulating materials are susceptible to being charged with static electricity due to friction, etc.
The scale is not dustproof or waterproof. Install the scale in a location where it will not become wet.
When the AC adapter is connected to an unstable AC power supply, it may malfunction.
Turn on the scale using the

ON/OFF

key and keep the weighing display on for at least 30 minutes

before use.

4.2. Precautions When Weighing
Do not place a load exceeding the weighing capacity on the weighing pan.
Do not apply shock to or drop anything on the weighing pan.
Do not use a sharp instrument such as a pen to press switches.
Press the ZERO key before each weighing to reduce weighing errors.
Periodically confirm that weighing values are correct.

4.3. Precautions for Storing
Do not disassemble the scale.
Wipe using a soft cloth slightly moistened with a mild detergent when cleaning the scale. Do not use
organic solvents. Using organic solvents such as MEK may cause the display to become so opaque that it
cannot be properly seen.
Prevent water, dust and other foreign materials from getting into the scale.
Do not scrub with a brush or the like.

11.1. Total (M+) Function
The scale can accumulate count data manually (by pressing theM+key) or automatically.

The number of pieces accumulated and the number of additions (how many times the total was addedto) can be viewed with the

TOTAL

key.

Adding Data Manually (by pressing the

M+

key)

1. When the weighing value is stable (stable mark is lit),press theM+

key. The scale accumulates thenumber of pieces that have been counted, and theM+ mark blinks for a few seconds.

2. Remove counted pieces from the weighing pan. The scale cannot continuously add the same data.
Before the next addition, the scale needs to return to near zero.
When the scale has accumulated data, the M+ mark lights up.
If the scale beeps four times and the M+ mark does not blink, refer to the following note.
TheM+

key is usually accepted only once normally when positive count data is

stable. Once accepted, the next accumulation cannot be done until the scale returns tonear zero.
The scale cannot accumulate data at near zero.
If function setting

is set to “ ”, theM+

key can accumulate even negative

data. In this case as well, the next accumulation cannot be done until the scale returns
to near zero.
Even if data is accumulated to the total value called up from the memory, the total value
in the memory is not updated. To store it in the memory, follow the procedure describedin “11.5. Calling Up Unit Weight and Total Count Together”.

Erasing the Last Added Data
1. Hold down theC

key and press the

M+

key.

Hold down thekey

and press thekey

2. Only the one data instance that was added last is erased fromthe total value.

be erased.

Automatic Accumulation
The number of pieces counted can be automatically accumulated. When the weighing value is stable(when the stable mark is lit), the number is automatically accumulated and the scale beeps one time.
For the next accumulation, remove counted pieces so that the scale returns to near zero.
To use automatic accumulation, set function setting

to “ ”.

Automatic accumulation is operable with positive count data only. Even if function setting
set to “ ” (Accept positive/negative data), the negative count data is not accumulated.

15. ACAI
15.1. ACAI Function
When unit weight is calculated, the larger the number of samples are, the less error is caused because
variation in weight per sample is averaged. However, it is difficult to precisely count a large number of samples.
With the ACAITM (Automatic Counting Accuracy Improvement) function, counting can be started with a small
number of samples. And each time samples are added within the range that does not cause counting errors,
unit weight is re-calculated and updated.
Precautions for using ACAI
Make sure to use the ACAI function after registering unit weight. Also, leave samples on the weighing pan.
Do not remove samples from the weighing pan until ACAI operations are finished.
There is no need to precisely count samples to add. The range of addable number of pieces is that where
the ACAI mark lights up.
Repeatedly perform ACAI operations up to near the maximum number of pieces to count.
Even if the same samples are to be counted, to precisely count them, keep registering the sample andperforming ACAI operations every time.
If unit weight is set with the numeric keys or unit weight is called up from memory, it is regarded that 10
samples are registered. With the factory setting, operations are performed manually (with the
ENTERkey). To switch to automatic operation, set function setting

to “ ”, andto “ ”.

15.2. Automatic Operation of ACAI
1. Before performing ACAI operations, register a unit weight.
Leave samples on the weighing pan.

2. Add samples within the range where the ACAI mark lights up (referto the table on the next page).

ACAI markThe ACAI mark lights up within the range where ACAI is possible.
As a rough standard, about the same number of pieces as thatwhich is shown in the display can be added.

is performed automatically.
When unit weight is re-calculated with ACAI being performed, the ACAI mark blinks and the unit weightdisplay changes to the unit weight value that has been re-calculated.
4. Repeatedly perform ACAI operations until the number of samples becomes sufficient (until it reaches thenumber to be actually counted).

15.3. Manual Operation of ACAI
ACAI operations can be performed manually. Press the ENTER key to re-calculate the unit weight.
To manually perform ACAI operations, set function setting

to “ ”.

1. Before performing ACAI operations, register a unit weight. Leave samples on the weighing pan.

Add samples within the range where the ACAI mark lights up (refer to the table in “15.2. Automatic

The UFC (Universal Flex Coms) function enables arbitrary descriptions to be output when weighing data is output.
Send a program command corresponding to the output format, to the scale and make it store thecommand. The program command stored is held even if the power of the scale is turned off.
The number of characters used for the program command is up to 1000.
To use the UFC function, the UFC format needs to be stored in the scale in advance.
To use the UFC function, set function

to “ ”.

The beginning of program command should be “PF,”.
The end of program command (the end of string) should be <CR><LF>.
The variable command is replaced with the scale's weight data or tare data.

Use upper case characters for the command above.
ASCII character strings
Enclose arbitrary ASCII code character strings in single quotation marks. Usable character strings arealphabet, numeric, and symbol. Single quotation marks in the string are shown using two single quotation
marks.
Ex.) When outputting character string ABC:
When outputting character string ‘ABC’:‘ABC’‘‘‘ABC’’’ASCII control code
Enter ASCII control codes with # and two characters in hexadecimal.
Ex.) When outputting <EOT> (04h): #04
Data repetition
Control codes $SP, $CR, and $LF can be repeated for the number of numeric characters used for eachcode ifand numeric characters (up to two characters) are added after them.

Ex.) When outputting 12 spaces:$SP 12

When outputting 9 <CR>’s:$CR 9

Combining markWhen two or more lines of program commands are sent, it is judged that the program command continues
to the next line if “&” (&<CR><LF>) is added to the end of a line.
Ex.) $WT$CR$LF&<CR><LF>
To separate each data, use a space or “,”. Although the separation is also a part of characters to be
stored, it can be omitted to reduce the number of characters. However, “,” for the program command
header cannot be omitted. Make sure to start it with “PF,”.
In the UFC format, a terminator is not automatically sent. Put a terminator code ($CR$LF) at the end ofcharacter data as needed.
Put a terminator code ($CR$LF) immediately before the last terminator <CR><LF> of the programcommand. Depending on the printer or data processing software, output may be properly performed withthe data format created.
The scale sends an error code if there is a problem when receiving a program command. It sends<AK><CR><LF> if there is no problem.

Press theREMOTE SCALE

key in weighing mode to switch to the remote scale. Confirm that it canproperly weigh.

70Caution When Using Remote Scale
To count with an accurate unit weight, register the unit weight with a sample by using the main scale andperform ACAI. Then, switch to the remote scale.
Perform tare subtraction with the main scale and remote scale respectively.
When using a remote scale, if the unit weight is registered with the main scale and then it is switched to aremote scale, ACAI does not work. The opposite is also same.

Required Specifications of Remote Scale
A weighing platform with up to four 350 Ω load cells can be connected.
The range of the remote scale’s weighing capacity is from 0.001 kg to 500000 kg.
When weighing capacity/minimum display exceeding 1/10000 are set, internal sensitivity per 1 d isreduced.
Output from the weighing platform should be within the range of ± 1.0 to ± 3.5 mV/V when loading up to
weighing capacity. The power source of load cell is 5 V.
Input sensitivity of load cell
Input sensitivity “X” of the load cell is as follows, given that rated output of the load cell is “A”, its capacity is“B”, and minimum display is “D”.
X=

5[𝑉𝑉] × 𝐴𝐴 × 𝐷𝐷
× 1000[𝜇𝜇𝜇𝜇]
𝐵𝐵

Make input sensitivity “X” of the load cell to be 0.5 µV or greater.

With the example below, input sensitivity “X” of load cell is 1.5 µV.
- Rated output of load cellA

3 mV/V- Capacity of load cellB

100 kg- Minimum display

D

0.01 kg

To maintain good performance, keep the length of the load cell cable up to 5 m.

71

18.3. Separation of Display/GC-08
The display can be separated from the main scale. The length of cable between the display and the scale isapproximately 1 m. With the GC-08 (extension cable), the length can be extended up to 2 m.

If the operation is done with the weighing pan facing downward, excessive force will be placed on thescale, which may cause damage.
To reattach the display after separating it, attach it to the main scale in the reverse order.
In doing so, be careful not to get the cable caught between the devices.
