6 Routine Care and Maintenance
General
Once the scale is installed, it is recommended that the assembly be
periodically inspected and calibrated by an authorized Mettler Toledo
representative. If the scale is used for legal-for-trade purposes, consult
the local Weights and Measures Authorities for minimum inspection
requirements. Contact your local authorized Mettler Toledo Service
representative for information on periodic inspection and calibration
services.
Site Inspection
Ensure that the scale site remains in good condition. Check for
alterations in the surrounding floor, excessive vibrations, and possible
overloading conditions.
Platform Inspection
During periodic inspections of the scale assembly, check the following:
1. Is there any unusual wear points, paths, or marks on the weighing
surface?
2. Is the scale frame bent or damaged?
3. Is the junction box lid properly sealed and all cable connectors tight
against the enclosure?
4. Is there any moisture or foreign material present around or inside the
junction box assembly?
5. Is the instrument cable free from damage or binding the scale?
6. Is there any debris or material build-up under or around the platform
which could inhibit freedom of movement?
7. If a pit installation, is the floor drain clear and providing adequate
drainage?
8. Visually inspect the load cells, rocker pins, and fixed bumpers for
signs of unusual wear.
9. Check repeatability and shift of the scale.
