Update L/C meter

After find more component for building the L/C meter design by VK3BHR. It can run until programed to MCU. Then supply 9VDC to board and adjust the Voltage for supply a contrast of display. I found the display has indicate "CALRIB", the program has running but its dos't continue to start. After problem occur I check the board what is wrong? Guess the problem is a relay pin isn't correct. I must go to shop again for get correct part for repair.
