How we check the trim gap in panel checker for sheet metal?

To check the trim gap in a panel checker for sheet metal, first ensure the panel is properly secured in place. Use a feeler gauge or gap gauge to measure the distance between the edges of the panel and the adjacent surfaces or components, ensuring it meets specified tolerances. Record any discrepancies and adjust the trim as necessary to achieve the desired alignment and fit. Finally, repeat the measurement to confirm the gap is within acceptable limits.
