Concrete pour went wrong thanks to a bad sensor reading...
We used a digital moisture meter to check the mix before pouring. It gave the all-clear, but the slab cracked within days. Now I'm confused about how often these things need calibration... and if old-school methods are better sometimes.
Ever think we rely on the screen too much? That old bucket test seems to work because it's simple and hands on, not just some number you hope is right. Maybe the tech needs a real world check more than we do.
Sensor drift is a real thing, but it's not the only reason. Calibration can fix that. The bucket test is good for a total system check. It catches stuff like a clogged filter or a bad pump that a sensor reading alone would miss. It's about verifying the whole chain works.
