Search Mode

1. Access Search Mode on the scale.
2. Retrieve the desired unit weight from the internal or external memory data.

Data Storage and Retrieval

The GC Series Counting Scales offer extensive data storage capabilities. Follow these steps to manage data:

Internal Memory

1. The internal memory can store data for up to 1,000 items.
2. Each item can have a 20-character item code, tare weight, total count/number of additions, and comparator limits.
3. An ID number and unit weight are also stored for each item.
4. The unit weight currently in use is backed up with the ID number 000000 for easy retrieval after reset or power-off.

MicroSD Card Memory

1. Insert a MicroSD card into the scale (ensure compatibility with the device).
2. Create and save item data in CSV format on the MicroSD card using a PC.
3. Retrieve unit weight and other information directly from the MicroSD card or transfer the list file to the internal memory of the scale.

For more detailed information and instructions, refer to the user manual provided by A&D.

Because All You Want to Do Is “Count”
If people appear to be counting faster, it may not be that they are better trained. Featuring A&D’s uniquely innovative solutions, the GC series of counting scales let you spend much less time and effort on setup and preparation so that you can start counting right away. The GC series is also designed to be able to connect with various other devices to expand their capabilities as needed, while being extremely functional as well as being affordable enough to be purchased for stand-alone operations.

Multiple displays for different purposes

For maximum efficiency and ease of operation, the scale has three separate reverse-backlit LCD displays for count, weight, and unit weight data, and one OLED*1 information display.

• 1 Organic light-emitting diode
  

• The count and weight displays can be switched if you prefer that weight data be displayed in the larger character size.

Information display also acting as a simplified guide for internal settings

• In addition to icons and animations which help you intuitively grasp what operation is currently being performed, it indicates parameter contents as a simplified guide during internal settings so you need not refer to the instruction manual every time.
• Example of the response speed setting assisted by the OLED information display

Separable display unit
The display unit can be detached from the weighing unit for ergonomic use depending on the device layout. The length of the standard cable that connects the display and weighing units is approx. 1 m. An optional extension cable (GC-08, approx. 2 m) is also available to replace the standard cable.

• Display unit detached from the weighing unit

Diverse methods of unit weight setting
You can select one of three ways to set a unit weight (= weight of one piece of the item to be counted) as the situation demands.

• Sample Mode: Have the scale calculate the average piece weight from the total weight of a preset or arbitrary number of sample pieces.
• Key Mode: Enter a known unit weight value using the numeric keys on the scale or from an external device such as a PC.
• Search Mode: Call up the unit weight to use from the internal or external (MicroSD card) memory data.

Unit weight entry navigator
No need to worry even if you are an inexperienced user. The scale navigates you through unit weight setting with text and small red LED lamps as it is turned on. Example of selecting Sample Mode to set a unit weight

Large internal memory to store data for up to 1,000 items

To recall and immediately use at any time, the GC series can store 20-character (max.) item code, tare weight, total count / number of additions and comparator limits, on top of 6-digit ID number and unit weight for as many as 1,000 items.

Unit weight backup
The unit weight currently in use is backed up in the internal memory with the ID number 000000 so that it can be retrieved at once even if the scale is accidentally reset or turned off.

Memory capacity extension using a MicroSD card

• The GC series also allows for the insertion and reading of a MicroSD card,*2 to which data for a practically infinite number of items can be created and saved in CSV format using a PC.
  • You can either call up the unit weight and other information of a desired item directly from the MicroSD card, or transfer the list file to the internal memory of the scale.*3
  • 2 Operation is not guaranteed for all MicroSD cards.
  • 3 The first 1,000 items will be copied if the number of items in the list file exceeds 1,000.

Automatic Item Search (AIS)♦ to instantly find a desired unit weight

• Individual item data can be easily called up from the vast list in the internal or external (MicroSD card) memory by entering an ID number or item code (the scale performs a case-sensitive prefix search when searching for an item code).
  • Patent pending
• Furthermore, when the Automatic Item Search (AIS) function is used, the scale will automatically find and set an item (unit weight) based on the weight detected by the scale.4 You simply have to place a piece of the item you are counting on the scale, and confirm whether the set item is the one you are looking for (or change to next match5 if it is not) so that counting can begin straight away.

• Just place a piece of the item you wish to count on the pan.
• The scale automatically sets a unit weight based on the weight on the pan.

Not only can this function save the hassle of having to enter an ID number / item code, but it can also be extremely helpful in case you have difficulty remembering the ID number / item code for the pieces at hand.

• 4 Effective only when the unit weight is outside the near-zero range (±4 scale divisions in kg).
• 5 For the internal memory, ten closest unit weights within approx. ±5% of the weight on the scale are suggested in approximate order. For the external (MicroSD card) memory, all unit weights within approx. ±5% of the weight on the scale are suggested in order of listing in the file.

Any counting scale can let you perform counting. The GC series also tells you what you are counting.

WinCT-Counting (freeware) for easy management of item data

Consisting of four useful modes, the WinCT-Counting software lets you perform various tasks on a PC to enable more effective and efficient use of the GC series.

• UFC Mode
  Useful for editing and sending UFC setting commands to a counting scale for customization of printout content and layout.

• Power supply from a mobile battery is especially convenient if the scale is to be carried and used at different locations.
• For reference, continuous operation time with an off-the-shelf mobile battery is estimated to be approx. 24 hours for 5,000 mAh and approx. 50 hours for 10,000 mAh with comparator lights off and no other external device connected to the scale.
  • 6 Type-C on the scale side and Type-A on the other side. Data communication is not supported.
  • 7 Operation is not guaranteed with other AC adapters, USB ports of all devices, or all mobile batteries.

RS-232C interface that supports digital connection with an A&D

balance/scale

The GC series is also equipped as standard with an RS-232C (D-Sub 9-pin) interface so that bi-directional serial communication (i.e. sending data and receiving commands) with an external device such as a printer or PLC can be made. Moreover, an A&D balance/scale can also be connected via the RS-232C interface,*8 which allows a high-precision balance to be used to set a minute unit weight, or a large-capacity/platform scale to be used to count the target item of a large quantity.Example of connecting an A&D analytical balance (GX- 324AE) to the GC series

• 8 A crossover RS-232C cable is required (AX-KO1371-200 is available from A&D). The RS-232C (D-Sub 9-pin) interface of the AD-8561 series described below cannot be used for this purpose.

Expanded scope of application using the AD-8561 series of Multi-Interfaces (sold separately)

With one of the following Multi-Interface options (connected to the RS-232C interface of the scale), multiple different devices can be used with the GC series. All of these options have one RS-232C (D-Sub 9-pin) interface and one USB (Type-A) interface, in addition to one interface specific to each model, as shown in the table below.
