Shovel Loader Indicator with COM RS232, Onboard Weighing Systems With High Precise
Loading Verification
- Keep Calibrating Weight [the materials weight in the bucket for Span Calibration] unchanged.
- BUCKET-UP: Flip the bucket upward to the limit position.
- ARM-DOWN: Put the lift-arm down so that the bucket goes down to the lowest position.
- Press key【Load】to enter loading state with the blue sign ‘▲’ displaying.
- Lift the lift-arm and bucket with the accelerator at the actual loading operation state and do the best to keep the accelerator stable.
- After the Magnet Block passed by the Weighing Segment, display blue sign ‘▼’ and record weighing result.
- Repeat the above steps, if the weighing errors are in the allowable range, the preliminary Loading Verification process is completed.
- Do Loading Verification with empty bucket, 1/2 bucket materials and a full bucket of materials, and use truck scale for checking weighing error.
- If the weighing errors are in the allowable range, the last Loading Verification process will be completed.
- Press key【Pause】to enter Pause state with red sign ‘■’ displaying.
- Press key【Cls】to Clear Screen without saving Loading Record.
