4.1 Troubleshooting
For troubleshooting details, see the following information:
Periodic Maintenance
The space beneath the platform must be periodically cleaned to prevent debris buildup.
Do not attempt to use scales with non-hermetically-sealed load cells in washdown applications. Water damage
is a common cause of failure in non-hermetically-sealed load cells.
Use care with high pressure steam washdowns for hermetically-sealed load cells. Steam will not damage the
load cells, but the elevated temperatures may cause incorrect readings until the unit cools to room temperature.
