The HRB Series intelligent weighing scale is a high-resolution balance designed for professional weighing and counting applications. This device is engineered for simplicity of operation, ensuring that users can quickly and efficiently perform various weighing tasks.
Function Description
The primary function of the HRB Series is to provide accurate weight measurements and facilitate piece counting. It operates as an electronic precision balance, capable of handling solid materials and liquids contained in secure vessels. The scale features a user-friendly interface with a bright backlit LCD display that shows weight readings, unit of measurement, and various indicators such as low battery, negative values, and zero status.
The scale incorporates several key functions accessible via its control panel:
- On/Off: This key powers the balance on or off. A hard switch is also located at the bottom of the unit for complete power disconnection.
- Zero: The Zero key is crucial for taring, allowing users to subtract the weight of containers multiple times within the scale's capacity. It also serves to re-adjust the scale to a correct zero position.
- Print: This function sends data to an external device via the RS232 connector, enabling seamless integration with other systems for data logging or analysis.
- Unit: The Unit key allows users to toggle between different units of measurement, providing flexibility for various applications.
- PCS (Pieces): This key activates the piece counting function, which is ideal for inventory management or counting small components.
The HRB Series also includes several programmable options to customize its operation:
- Interface Settings: Users can configure the RS232 communication parameters, including baud rate (e.g., 1200, 2400, 4800, 9600) and parity mode (odd, even, or none), to ensure compatibility with external devices. The print mode can also be set to manual (KEY), automatic when stable (STB), or continuous (CON).
- Zero Range Settings: The scale allows for adjustment of the zero range when powered on, as well as the zero range for the ZERO key and the TARE key. These settings help maintain accuracy and flexibility in different weighing scenarios.
- Overload Range: The overload range can be configured to prevent damage from excessive weight, providing a safety mechanism for the device.
- Beeper: The beeper function can be switched on or off, providing audible feedback for various operations.
- ZERO and TARE Function Merge: This setting allows users to enable or disable the merging of the ZERO and TARE functions, offering further customization of the scale's behavior.
- Auto Shut Off: To conserve power, the auto shut-off mode can be enabled or disabled, allowing the scale to automatically turn off after a period of inactivity.
- Backlight: The backlight for the LCD display can be set to "On," "Off," or "Auto," providing optimal visibility in various lighting conditions.
Usage Features
The HRB Series is designed for ease of use and reliability in professional environments.
- High Resolution: The scale offers high resolution, ensuring precise measurements for critical applications.
- Stability Indication: A stability indicator on the display informs the user when the weight reading is stable, ensuring accurate data capture.
- Fast Display Setting Time: With a display setting time of less than 1 second, the scale provides quick and efficient readings, enhancing productivity.
- Auto Zero Tracking: This feature automatically maintains the zero point, compensating for minor fluctuations or debris on the pan, ensuring consistent accuracy.
- Large Stainless Steel Pan: The large stainless steel weighing pan is durable, easy to clean, and suitable for a wide range of items.
- Unit Switching: The ability to switch between various units (g, ct, oz, tola) makes the scale versatile for different industries and applications.
- Counting Function: The piece counting function is straightforward to use. After placing a known number of samples (e.g., 10, 20, 50, or 100 pieces) on the pan and confirming the sample quantity, the scale can accurately count additional items.
- Auto Calibration: The scale supports external calibration, allowing users to maintain accuracy over time by using a known test weight. This process involves a warm-up period, entering calibration mode, adjusting the flashing digit to match the test weight, and then placing the weight on the pan.
Maintenance Features
Proper maintenance is essential to ensure the longevity and accuracy of the HRB Series weighing scale.
- Regular Cleaning: The scale requires regular cleaning. The weighing pan and its holder should be cleaned by removing dirt or dust from underneath and on the housing. A soft brush or a lint-free cloth moistened with a mild soap solution is recommended.
- Avoid Harsh Chemicals: It is crucial to avoid using solvents, acids, alkalis, paint thinners, scouring powders, or other aggressive or corrosive chemicals, as these can damage the surfaces of the scale housing.
- Power Disconnection for Maintenance: For any maintenance work, the balance must be disconnected from the power supply by removing the power adapter plug from the socket. This prevents accidental power-on and ensures user safety.
- Liquid Spill Precaution: Care must be taken to prevent liquid spills into the scale during maintenance. If a spill occurs, the scale must be inspected by a service technician before further use.
- Proper Storage: If the scale is to be taken out of service for an extended period, it should be disconnected from the electricity supply, thoroughly cleaned, and stored in a place free from violent shaking, vibrations, extreme temperature fluctuations, direct solar radiation, and excessive moisture. The original packaging is recommended for storage and transportation to protect the device.
