1. Preparation

Ensure that you have the following materials before starting the procedure:

• Multimeter (with Peak Function, if available)
• Screwdriver for Potentiometer Adjustment

2. Disconnecting Power

1. Turn Off the Power
   • Disconnect the power cable from the Local Indicator to prevent electrical damage.

3. Connecting the Multimeter

1. Connect the Red Cable
   • Attach the red cable as shown in the reference image.
2. Connect the Multimeter Probes
   • Place the multimeter rods between both black cables.

4. Adjusting the Current (mA) Value

1. Turn VR4 Potentiometer Clockwise
   • Rotate the VR4 potentiometer clockwise until the current (mA) value stops changing.
2. Set the Current to 40 mA
   • Adjust VR3 potentiometer until the current reaches 40 mA.
3. Fine-Tune Using VR4
   • Readjust VR4 potentiometer, noting the rising and falling pattern.
   • At the peak point, adjust VR4 to 50 mA.
   • If the value is not displayed on the monitor, adjust the current between 40-45 mA.
   • ⚠️ Tip: If the multimeter has a Max Peak function, use it for accurate peak current detection.

5. Verification

• After completing the adjustment, verify that the current (mA) value is correctly.

6. Special Note for PCB Type Differences

• Old Type (3 PCB): Uses VR1 and VR2 for adjustment.
• New Type (2 PCB): Uses VR3 and VR4 for adjustment.
