Measure the input and output resistance
1. Disconnect the load cell.
2. Measure the input voltage between EXC+ and EXC-.
3. Measure the output voltage between SIG+ and SIG-.
The resistances must correspond to the values specified in the data sheet or in the specifications.

Measures in the event of overloaded load cells
A frequent fault that can result in failure of load cells is overloading due to
• dynamic overload
• transverse forces
When you establish that the cause of the fault was overloading, further measures are necessary.
Dynamic overload
Example:
Unintentional falling of a relatively low weight onto the load carrier from a great height.
Possible measure:
• Install shock-absorbing components, e.g. elastomer bearings
• Overdimension the load cells
Transverse forces
Example:
Accelerating or braking loads onto a platform.
Possible measures:
• Install guide elements
• Install oscillation limitation or set it to a lower value.
