Figure 3.5 Description: A diagram shows how to measure the rim's outer side distance (AE) and outer diameter (dE) using the offset arm and a ruler. Text "Read the scale measurement here." is displayed.

Note on Diameter Measurement: The inner and outer diameters of the rim can be obtained by two methods: 1. Measure directly with a soft ruler. 2. Subtract 1 inch (25mm) from the inner diameter and 2 inches (50mm) from the outer diameter based on the diameter marked on the rim.

Balance Weight Block Split Hidden Function

3.4 Balance Weight Block Split Hidden Function

This function divides the outer weight "W" into two smaller weights, W1 and W2, allowing the user to paste them at two operator-selected points. The positions of W1 and W2 must be on both sides of W, with an angle not exceeding 120 degrees (See Figure 3.6).

Figure 3.6 Description: Schematic diagrams illustrate the correct and incorrect placement of balance weights for the hidden function. "Right" shows W1 and W2 sandwiching W with an angle less than 120 degrees. "Wrong" examples show angles greater than 120 degrees or W not between W1 and W2.

This function is used for aluminum alloy rims to hide the outer balance weight behind spokes. Do not use it if the weight position aligns with a spoke. The hidden function can be used in static balance mode, particularly for motorcycle tires.

Procedure:

• Press [F] + [ALU]. If the outer unbalance value is not 0, the machine enters the balance weight split hidden mode (display shown in Figure 3.7).
• If the outer unbalance value is 0, the operation is not available (display shown in Figure 3.8).
• Manually turn the wheel until all outer unbalanced position indicator lights are on.
• Turn the tire to the selected W1 position and press [C] to confirm. The angle between W1 and W must be less than 120 degrees.
• If the angle is greater than 120 degrees, a buzzer will sound, indicating an incorrect selection. If the angle is less than 120 degrees, the machine displays information as in Figure 3.9, entering the W2 selection state.

Figure 3.7 Description: An image of the balancer's digital display shows "- - -" and "P61", indicating the input stage for balance weight W1 position.

Figure 3.8 Description: An image of the balancer's digital display shows "8FF" and "- - -", indicating that the balance block split hide function is not available.

Figure 3.9 Description: An image of the balancer's digital display shows "- - -" and "P62", indicating the input stage for balance weight W2 position.

• Manually turn the tire to the selected W2 position and press [C] to confirm. The angle between W1 and W2 must be less than 120 degrees and sandwich W.
• If the angle between W1 and W2 is greater than 120 degrees, a buzzer will sound, indicating an incorrect selection. If the angle is less than 120 degrees, the machine displays the value of balance weight W2.
• Lock the tire and paste the balance weight W2 according to the grams shown on the screen.
• Manually turn the tire to the previously selected W1 position until all unbalance position indicator lights are on. Lock the tire and paste the balance weight W1 according to the grams shown on the screen.
• After pasting weights at W1 and W2, press [F] + [ALU] to exit the split hidden mode.
• Restart the measurement to verify the balance effect.

Wheel Balancing Procedure

3.5 Wheel Balancing Procedure

• Install the tire on the axle (See Figure 2.1).
• Select the appropriate balance mode and the installation position for the balance weight as shown in Figure 3.0.
