1. Understanding the Electronics and Connection Compartment

The Local PCB uses Hall IC switches (A, B, C, D) for data input and adjustments. The function of each switch is as follows:

• A Switch: Increases the flickering digit.
• B Switch: Shifts the flickering rank by placing a magnet on the switch (hold for less than 3 seconds).
• C Switch: Decreases the flickering digit.
• D Switch: Registers the entered data.

⚠️ Note: The switch reacts to only one magnet polarity.

2. Local Indicator Setting Procedure

Step 1: Enter Parameter Mode

1. Place a magnet on the B switch and hold for over 3 seconds.
2. The operation mode will switch to Parameter Mode, displaying "C00".

Step 2: Access Ullage Mode Setting

1. Shift the displayed code to "C09" by using:
   • A switch (to increase).
   • C switch (to decrease).
2. Enter the password "1234" and confirm by placing the magnet on D switch.
3. "C10" will be displayed.

Step 3: Set Ullage Mode

1. Shift the code to "C10".
2. Input 1 (Ullage mode).
3. Confirm by placing the magnet on D switch.

Step 4: Save and Exit

1. Place the magnet on B switch and hold for over 3 seconds.
2. The system will return to operation mode, saving the settings.

Important Notes:

⚠️ Caution: Holding the B switch for too long in certain modes may cause unintended changes.
⚠️ Warning: Always verify the ullage setting to ensure proper measurement adjustments.
