Safety Instructions

Always operate the scale on a stable, level surface to ensure accurate measurements.
Avoid exposing the scale to extreme temperatures, humidity, or direct sunlight.
Do not overload the scale beyond its maximum capacity of 6 kg.
Keep the scale away from strong electromagnetic fields, which can affect accuracy.
Use only the specified power adapter and battery type (1 x 9V battery) for the device.
Do not attempt to disassemble or repair the scale yourself. Contact qualified service personnel.
Clean the scale with a soft, damp cloth. Do not use abrasive cleaners or immerse the unit in water.

Setup

1. Unpacking

Carefully remove the counting scale from its packaging. Retain the packaging for future transport or storage. Check for any visible damage. If damage is present, do not operate the device and contact your supplier.

2. Power Supply

The scale can be powered by the included 9V battery or an appropriate AC adapter (not specified if included, assume external or internal rechargeable). Ensure the battery is correctly inserted according to polarity markings. For AC power, connect the adapter to the scale's power input and then to a suitable power outlet.

3. Placement

Place the scale on a firm, level, and vibration-free surface. Avoid locations near air vents, windows, or machinery that could cause air currents or vibrations, as these can affect measurement accuracy.

4. Initial Zeroing

After powering on, allow the scale a few minutes to warm up. The display should show "0.000" or similar. If not, press the ZERO or TARE button to set the display to zero before weighing.

Operating Instructions

1. Power On/Off

Press the ON/OFF button (usually located on the front panel) to turn the scale on or off. The scale will perform a self-test upon startup.

2. Basic Weighing

Ensure the scale is on a stable surface and the display shows zero.
Place the item(s) to be weighed gently on the center of the weighing platform.
Read the weight displayed on the WEIGHT screen. The scale supports units in kilograms (kg) and pounds (lb). Use the unit conversion button (if available, often labeled UNIT or kg/lb) to switch between units.
To tare (zero out the weight of a container), place the empty container on the platform and press the TARE button. The display will return to zero, allowing you to weigh only the contents.

3. Counting Function

The 9221 scale is optimized for counting. To use the counting function:

Place a known sample quantity (e.g., 10, 20, 50 pieces) of the items to be counted on the platform.
Enter the number of sample pieces using the numeric keypad.
Press the SAMPLE or PCS button (refer to specific button labels on your device, often indicated by an icon like →→→ or →→→ with dots). The scale will calculate and store the average piece weight.
Remove the sample and place the bulk quantity of items on the platform. The PIECES display will show the total count.
The PIECE WEIGHT display shows the calculated weight of a single item.

4. Memory Functions (M1-M5, PLU)

The scale features a large memory for 1,000 reference weights and quick access via 5 direct keys (M1-M5).

Storing Piece Weight: After determining a piece weight (e.g., via sampling), press a memory key (M1-M5) or the PLU button followed by a numeric code to store the piece weight for that item.
Recalling Piece Weight: To recall a stored piece weight, simply press the corresponding memory key (M1-M5) or enter the PLU code and press PLU again. The scale will then use this stored piece weight for counting.
Quick Article Access: The 5 direct keys (M1-M5) allow for immediate recall of frequently used item piece weights.

5. USB Interface

The scale is equipped with a USB interface for connection to a PC. This allows for data transfer, such as weighing results or inventory data, to compatible software. Refer to the software's documentation for specific connection and data transfer procedures. A USB cable is typically required (check product contents).

Maintenance

Cleaning: Wipe the scale's surface with a soft, slightly damp cloth. Do not use harsh chemicals, abrasive cleaners, or excessive water. Ensure no liquids enter the internal components.
Battery Replacement: When the low battery indicator appears on the display, replace the 9V battery promptly. Ensure the scale is turned off before opening the battery compartment and inserting the new battery with correct polarity.
Storage: If the scale will not be used for an extended period, remove the battery to prevent leakage. Store the scale in a dry, dust-free environment at moderate temperatures.
Calibration: While the scale is factory calibrated, periodic checks with certified weights are recommended for professional applications to ensure continued accuracy. Refer to local regulations for calibration requirements.
