## Manual Hydraulic Validation

1. Raise and lower the implement using manual controls.
2. Confirm smooth movement.
3. Confirm correct movement direction.
4. Confirm full travel can be achieved.
5. Verify no unexpected hydraulic behaviour occurs.

**Expected Result:**

- Implement responds immediately.
- Movement direction matches commanded direction (Up/Down/Left/Right).
- No instability or oscillation is present.

## Automatic Control Engagement Validation

Verify Automatic Control can engage and operate correctly:

1. Position the machine in a safe operating area.
2. Load a valid design surface.
3. Satisfy all engagement requirements.
4. Engage Automatic Control.

**Expected Result:**

- Automatic Control engages successfully.
- No engagement warnings are generated.
- Control outputs become active.

## Automatic Control Response Validation

Verify control outputs produce the expected machine response when Automatic Control is active.

1. Engage Automatic Control on the previously loaded design surface.
2. Observe implement movement.

**Expected Result:**

- Implement moves toward the design surface.
- Movement direction is correct.
- Correction occurs without hesitation.
- No excessive overshoot occurs.

## Grade Tracking Validation

<span style="white-space: pre-wrap;">Operate the machine under normal working conditions. Navigate to </span>**More** <span style="white-space: pre-wrap;">&gt; </span>**COMMAND Settings** <span style="white-space: pre-wrap;">&gt; </span>**Tuning**.

Observe:

- Current Error
- Commanded Output %
- Dynamic Performance Factor (DPF)

**Expected Result:**

- Current Error remains stable and controlled.
- Commanded Output % changes smoothly.
- DPF remains low and consistent.
- Automatic Control maintains the design surface without oscillation.
