11 Product Maintenance
METTLER TOLEDO warrants its products against defects in materials and workmanship for
twelve months from the date of installation or fifteen months from the date of shipment,
whichever comes first. For details, please refer to the warranty provided with the
instrument. For assistance, please email AutoChemCustomerCare@mt.com.
It is recommended that you retain the original packing materials if you need to return
the ParticleTrack system. If factory service is required, your METTLER TOLEDO service
engineer will issue you a Return Material Authorization (RMA) form.
There are no user-serviceable parts inside a ParticleTrack G400. Contact your
METTLER TOLEDO Field Service Engineer for all service needs.
Schedule the following maintenance tasks:
• Run the Calibration Validation procedure for the probe every three to six months, if the
probe is dropped or the system is transported, and after new software is installed, if
desired.
The “Calibration Validation in iC FBRM” procedure uses the PVC Reference Sample and
reference file, provided with the system. The procedure also requires a Fixed Beaker
Stand (FBS). Locate the procedure document in the ParticleTrack G400 Hardware
Portfolio.
• Clean the probe window periodically. To clean the outside window, use a medium
such as water, alcohol, or acetone to clear the surface. A fine, abrasive polishing
compound may be used to remove stubborn stains (0.3 micron alumina, used to
polish optical surfaces is recommended). After cleaning, use a dry, clean Kimwipe
®
to remove the cleaning solution. The probe window cleanliness can be verified in the
software.
• Ensure the air/gas supply meets the required standards, when using the optional
purge.
• Change bearings, if necessary, as recommended by METTLER TOLEDO. The average
life of the bearings on the ParticleTrack G400 is one to two years. Under normal
operating conditions, the probes should be serviced every other year during Preventive
Maintenance to ensure optimal uptime with no unexpected failures. Probes operated
at elevated temperatures and/or continuously must be serviced more frequently, and
in this case a Full Coverage Service Contract is recommended. To extend bearing life,
turn off the probe when not in use.
• The ParticleTrack G400 system is designed for indoor use, so the base unit and probe
back end can only be wiped clean. The wetted portion of the probe tip can be cleaned
with solvent such as ethanol, IPA, or soap and water.
