Operating Instructions
The W310 v2 offers multiple weighing modes to suit different operational needs. Familiarize yourself with the controls and modes for efficient weighing.
Controls Overview:
- Rotary Selector Knob: Used to navigate between different weighing modes and settings.
- WEIGH Key: Initiates a manual weighing cycle.
- ZERO Key: Zeros the scale before weighing.
- DELETE Key: Deletes the last recorded weight or clears data.
- F1/F2 Keys: Function keys for additional options or settings.
- Backlit Display: Shows weight, mode, battery status, and other information.
Weighing Modes:
Rotate the selector knob to choose your desired weighing mode:
- Auto-weighing Mode:
In this mode, the animal's weight locks automatically once stable, allowing for fast, hands-free weighing. This is ideal for high-throughput operations.
- Ensure the scale is zeroed before an animal enters the platform.
- Once the animal is on the platform, the scale will detect its presence and automatically lock onto a stable weight.
- The locked weight will be displayed and can be recorded or sent to connected devices.
- Manual Weighing Mode:
This mode gives the operator full control over the weighing cycle. The weight is recorded only when the WEIGH key is pressed.
- Place the animal on the platform.
- Wait for the animal to settle.
- Press the WEIGH key to capture and record the weight.
- Fine Weighing Mode:
Designed for small load weighing, this mode operates with no zero tracking for greater accuracy. It is suitable for precise measurements where minimal movement is expected.
- Ensure the platform is clear and stable.
- Place the item to be weighed carefully on the platform.
- The scale will display the precise weight.
Data Management:
- Statistics Display: The second screen provides statistics such as the number of animals weighed, maximum weight, and minimum weight.
- Sending Weights: If connected to an HR5 Hand Held EID Tag Reader or other devices via Bluetooth or communication port, weights can be sent and recorded against individual animal IDs.
