    Chapter 9: Routine Care and Maintenance General Routine Care and Maintenance General Once the scale has been installed, it should be inspected and calibrated periodically 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.

  • Page 36: Troubleshooting

    When troubleshooting a VERTEX floor scale, examine the scale’s physical location. Check for the presence of water, corrosive materials, unlevel floors, high vibrations, air currents, or physical damage to the scale platform or frame. Also check the instrument cable for damage, and all connections for loose or improper wiring.
