Hello, I have a 425 gaussmeter. I measured a permanent magnet's flux density as 6T. Theoretically, it seems impossible. Except for the calibration problem, what can I do possibly wrong? How should I measure the flux density of the permanent magnet?

Please tell me if the measurement was ever correct. Also, do you have a different probe or gaussmeter that you can compare the measurements with?
If anything is wrong, it most likely is the probe. The Hall sensor is in the tip and it is VERY sensitive. Abrasion, shock, etc., will damage the sensor easily which would cause such unexpected measurements. What happens when you zero the probe? Do you get a "larger offset than expected" error message at the end of the zeroing process?
