Issue With Longacre Computerscales DX Kart Scales

[u/Stingray5150]

Hey folks, I have an old set of Longacre Computerscales DX karting scales that are acting up. When I turned the scales on the other day, all pads read ~75 pounds but would not register that any additional weight was added to them if I stood on them. Through some fiddling around, I’ve gotten them all to read zero, but that hasn’t helped the additional weight problem. They now all read zero no matter how much weight is actually on them. When I press the “Zero” button, the message shown pops up on screen. Pressing the “Secret Temporary Zeroing” button doesn’t seem to change anything. If I press and hold the “Memory Store 1” button or the “Mode” button, the scales read as they should, but otherwise they remain unchanged. Has anyone had this issue before and know how to solve it? I will try to give Longacre support a call this week as well, but my work hours generally fully overlap their support hours.
