A39E Anti-Tamper Animal Weighing Indicator

• 6-digit 0.8-inch LED display
• 10 operating status indicators
• 6-key membrane keypad
• Built-in rechargeable battery
• Analog load-cell connection
• Sensor impedance anti-tamper monitoring
• Optional RS232 or Bluetooth communication

• Animal Weighing Mode: Provides a dedicated function for livestock weighing where animal movement may cause fluctuating signals.
• Anti-Tamper Monitoring: Detects abnormal sensor impedance conditions that may indicate unauthorized devices or wiring changes.
• Electronic Seal: Helps detect unauthorized opening or modification of the indicator's internal circuit.
• Abnormal Alarm Indication: Prompts the operator when anti-tamper security conditions are incomplete or abnormal.
• High-Resolution A/D Conversion: 24-bit Sigma-Delta conversion provides stable processing of analog load-cell signals.
• AC/DC Dual Power: Operates from AC 220 V / 50 Hz or the built-in 6 V / 4 Ah rechargeable battery.
• Long Battery Operation: Typical continuous operating time is approximately 40 hours after a full charge.
• Optional Data Communication: RS232 can connect to a computer, remote display or compatible POS58 thermal printer.
• Additional Functions: Supports simple counting and kilogram-to-pound conversion in addition to standard weighing.

• Pig platform and pen scales
• Cattle and calf weighing scales
• Sheep and goat crate scales
• Mobile livestock weighing systems
• Electronic floor scales
• Industrial platform scales
• Static weighing systems using analog load cells
• Weighing installations requiring anti-tamper monitoring

• Confirm that the scale uses compatible analog load cells before installation.
• Connect one to four load cells according to the specified four-wire wiring configuration.
• Keep weighing signal cables separated from motors, contactors and other high-power electrical wiring.
• Complete zero setting and calibration after installation or load-cell replacement.
• Perform the anti-tamper security setup before routine weighing operations.
• Check sensor impedance alarms if abnormal weight behavior or wiring changes are detected.
• Keep the indicator dry and protect it from direct high-pressure washing and excessive condensation.
• Recharge the battery regularly when the instrument is used without mains power.
• Confirm communication settings before connecting RS232 or Bluetooth devices.
• Calibration and electrical servicing should be performed by qualified weighing-system personnel.

Q: Does the A39E support animal weighing?
A: Yes. Animal weighing is one of the standard functions of the A39E and is suitable for compatible livestock weighing systems.

Q: What makes the A39E different from a basic weighing indicator?
A: It adds sensor impedance monitoring, anti-tamper alarm functions and an electronic seal to help protect the integrity of the weighing system.

Q: How many load cells can be connected?
A: The standard configuration supports one to four analog load cells using a four-wire connection.

Q: Can it work without AC power?
A: Yes. A built-in 6 V / 4 Ah rechargeable battery provides approximately 40 hours of typical continuous operation after a full charge.

Q: Can it connect to a computer?
A: Yes. An optional RS232 interface can be used for computer connection and other compatible peripherals.

Q: Is Bluetooth available?
A: Yes. Bluetooth 2.0 slave mode is available as an optional interface. The Bluetooth configuration does not provide RS232 output at the same time.

Q: Can a printer or remote display be connected?
A: With the optional RS232 interface, the indicator can connect to compatible computers, large displays and POS58 thermal printers.

Q: Is the A39E suitable for truck scales?
A: The A39E is primarily an analog platform-scale indicator supporting up to four analog load cells. Final suitability should be confirmed according to the load-cell quantity and wiring configuration of the weighing system.
