All our force gauges have an overload protection of 200% of the full scale of the sensor. Nevertheless, each time you measure more than 120% of the full scale, the Centor will count this as an overload.
After 10 overloads, the force gauge is locked in a safe mode.
To unlock your gauge, you have to send it to us to perform a complete diagnostic to check that the accuracy of your instrument is still in the tolerances.
