Calibration & Equipment Support

Equipment Performance and Calibration

How do you make sure that your mass properties instrument performs within factory specifications? Do you need to certify your instrument in order to prove the validity of your test results? Raptor Scientific is here for you. We test and certify mass properties equipment from all manufacturers.

We are NIST certified for the measurements of mass and distances, the two quantities used in mass properties. We recertify your calibration hardware. We use calibrated masses and distances to certify that your instrument is within its accuracy specifications for center of gravity, moment of inertia, product of inertia, and dynamic unbalance measurement. And if it is not, we perform maintenance service on your machine to restore it to original specifications.

Key Benefits

Accuracy of Test Results – Once we certify your instrument, you can be certain that the mass properties measurement results that you get are accurate to within the specifications of the machine.
Accuracy of Verification Method – The accuracy of our verification methods is often more than 10 times the rated performance of the system being evaluated.
Results traceable to Primary Standards – All reported performance values are traceable to the US NIST (National Institute of Standards and Technology).

All Raptor Scientific equipment comes with calibration hardware. This allows the operator to calibrate the instrument for center of gravity, moment of inertia or product of inertia.

Calibration hardware needs to be recertified periodically. Sending your calibration hardware back to Raptor Scientific for recertification ensures that your hardware is handled properly, recertified with the same method that was originally used for certification, and compared to original factory values. All our values are certified traceable to NIST (National Institute of Standards and Technology).

System support and available options are designed to ensure the integrity of the measurement system as well as provide a quality check on the data products that the system generates. Systems must have Basic Support to qualify for the Factory Service, Field Service, and Field Repair Options. No shipping costs are included; shipping is the customer’s responsibility and a Return Material Authorization (RMA) must be obtained prior to shipping. Systems received at Raptor Scientific without an RMA will not be accepted and returned to the customer.

Basic Support entitles customers to phone and email support for troubleshooting system failures and problem resolution. If problems are not able to be resolved via phone or email support, customers have the option to send their system to Raptor Scientific for evaluation and repair. The system evaluation is covered under the Basic Support at no additional cost and any necessary repairs will be quoted on a T&M basis. Without this minimum level of support, Raptor Scientific will not be able to service or troubleshoot customer systems. Unapproved customer modifications are not covered and will not be repaired by Raptor Scientific. Hardware upgrades are not considered repair actions and will be quoted appropriately.

Basic Support provides one (1) year of support for one (1) system. Support periods extending beyond one (1) year will be quoted at the annual rate, for full years, and will be prorated based off of the annual rate for partial years (e.g. 18 or 30 months of coverage).

Telephone Support

This allows users to contact Raptor Scientific for troubleshooting and problem resolution via email or phone. Calls must be made during normal working hours.

Priority Repair for systems returned to Raptor Scientific for service

Basic Support includes priority repair which has a goal of completing the repair within one (1) week after receipt of customer contractual authorization and funding, assuming the parts required for the repair are available. As available, Raptor Scientific may loan subsystems or components to customers, at no additional cost, while their system is being repaired. Roundtrip shipping of loaned equipment is the responsibility of the customer.

Software Updates

Updates provided as available.

Lapse in Support Coverage

Systems that have been off support for a period of one year or more will be assessed a surcharge of $2,500 per year for each year the system has been off support, NTE $10,000 for any one system.

Raptor Scientific reserves the right to refuse renewal of Support plans for systems that have been declared obsolete.

This add on service is important to maintain optimum performance of your system on a yearly basis. This service includes inspection, maintenance, including cleaning, lubrication, and necessary factory updates required to verify nominal Raptor Scientific radar system performance.

  • Factory calibration of radar is completed and RCS performance is evaluated.
  • The Factory Service Option allows one (1) system to be returned to the factory for servicing one (1) time per year.
  • All repairs and replacement parts are quoted and charged separately at T&M rates for parts and labor.

The system must be sent to the factory to perform this servicing. It is the customer’s responsibility to schedule services prior to the expiration of the Support Plan’s period of performance. Shipping costs are the responsibility of the customer. Any hardware upgrades requested by the customer will be quoted separately.

This add on service is important to maintain optimum performance of your system on a yearly basis. This onsite service offers inspection, maintenance and calibration of the radar and RCS performance is evaluated.

  • The onsite field service is costed with one engineer at a maximum of three days onsite plus travel time.
  • Calibration of radar is completed and RCS performance is evaluated.
  • The Field Service Option allows one (1) system to be serviced in the field one (1) time per year.
  • All repairs and replacement parts are quoted and charged separately at T&M rate for parts and labor.

If during the onsite maintenance any abnormalities are observed, Raptor Scientific offers no guarantee the system can be repaired onsite and no onsite repairs have been costed. Furthermore, repairs may require the system or subsystem to be shipped to the Raptor Scientific factory for evaluation and potential repair. Shipping costs are the responsibility of the customer. Any hardware upgrades requested by the customer will be quoted separately. Field service activities will be scheduled at mutually agreed upon dates based on current workload and resource availability at the time of scheduling. Raptor Scientific can support a limited number of Field Service activities each year. Raptor Scientific cannot guarantee the availability of this option; however, this will be confirmed and reserved upon contract execution.

Customers that have a support agreement may request to have a factory-trained technician come to the customer site for evaluation and possible repair of reported problems. Raptor Scientific will be onsite for service at the earliest possible convenience to execute the repair strategy which has been mutually agreed on with the customer. All travel and repairs are quoted separately and charged at T&M rates. Field repair premiums offset the burden of supporting these unforeseen activities in a timely manner. The premium is based on-site location and will be included on any associated field repair contract.

Note: Raptor Scientific offers no guarantee the system can be repaired onsite. If a system must be returned to Raptor Scientific’s factory for repair after the field evaluation, an updated T&M quote will be provided. Shipping costs is the responsibility of the customer.

Customers who manage multiple systems may contact Raptor Scientific to discuss the options related to consolidating the individual support plans for their systems.

Both the SCI-Xe-AC and Raptor Scientific -2k based systems, along with their associated spare components, are currently inactive and are no longer available for sale.
