Since a numerical display can only display 1 digit, you need to set its display digits.
0 means display single digits, 1 means display tens digits, 2 means display hundreds digits, 3 means display thousands digits, 4 means display thousands digits.
1. Place the numerical display from right to left and the game will automatically set the number of display digits.
2, the numerical display comes with the function of the signal cable, it will transmit the signal voltage, but only the left and right transmission signals, the upper and lower will not be transmitted, so the signal cable does not need to be placed repeatedly when placed horizontally.
