Product Showcase Content
Product Name A9P WEIGHING INDICATOR WITH BUILT-IN PRINTER
Product Image A9P Weighing Indicator with Built-in Printer
Product Overview The A9P Weighing Indicator is a high-precision analog weighing terminal designed for static electronic weighing systems using multiple load cells. It integrates weight display, data storage, printing, communication and calibration functions in one desktop instrument.

With a built-in dot-matrix micro printer, large LED display and multiple communication interfaces, the A9P is suitable for platform scales, floor scales, livestock weighing platforms and other compatible static weighing systems.
Product Gallery Desktop weighing indicator, 7-digit LED weight display, integrated dot-matrix micro printer, numeric function keypad, rear communication interfaces and compact 330 × 195 × 177 mm housing.
Key Features
  • High-Precision A/D Conversion: Uses high-precision Sigma-Delta analog-to-digital conversion technology.
  • Wide Signal Input Range: Processes analog load-cell signals from -16 mV to 18 mV.
  • Multi-Load-Cell Support: Supports up to 8 × 350 ohm or 16 × 700 ohm load cells according to system configuration.
  • 7-Digit LED Display: Large illuminated display provides clear weight readings and battery-status indication.
  • Built-In Printer: Integrated dot-matrix micro printer supports on-site weighing-ticket output.
  • Large Data Storage: Stores up to 1001 weighing records, 1000 vehicle/tare records and 201 goods codes.
  • Flexible Communication: Standard RS232 interface with optional RS422 or RS485 communication.
  • External Scoreboard Support: Current-loop interface allows connection to a remote large display.
  • AC/DC Operation: Supports mains power and compatible rechargeable battery operation.
  • Adjustable Calibration: Includes zero tracking, zero setting, two-point linear correction and compensation calibration functions.
Working Principle Compatible analog load cells convert the mechanical load applied to the weighing platform into a millivolt electrical signal. The A9P receives this signal through the load-cell connection and converts it into digital weighing data using its high-precision Sigma-Delta A/D converter.

After calibration and signal processing, the measured weight is shown on the LED display. The operator can perform zeroing, tare, data storage and printing operations, while weighing records can also be transferred to compatible computers, remote displays or external management systems through the available communication interfaces.

Installation & Maintenance
  • Match the indicator with compatible analog load cells and confirm total load-cell impedance before connection.
  • Disconnect power before connecting or servicing load cells, communication cables or external equipment.
  • Use the specified 6-wire load-cell connection where long-line compensation is required.
  • Complete zero setting and calibration after initial installation or major weighing-system service.
  • Keep the indicator in a dry, clean and well-ventilated location.
  • Do not expose the instrument directly to livestock-house washdown, high-pressure water or excessive condensation.
  • Keep printer paper correctly installed and remove paper dust periodically.
  • Inspect load-cell wiring, plugs, communication connectors and power cables regularly.
  • Back up or export important weighing records according to the user's management procedure.
  • Use qualified technical personnel for internal servicing and calibration adjustments.
