Setting Up An On-Site Visit

  • Send a list of instruments to be calibrated and a PO number to FLW. Your documentation is required to ensure you obtain the correct service and meet the requirements of ISO 9001:2015, QS 9000, and/or ANSI/NCSL Z540-1-1994. All include wording similar to ISO 9001 that states "purchasing information shall describe the product to be purchased, where appropriate: a) requirements for approval of product, procedures, processes and equipment, b) requirements for qualification of personnel, and c) quality management system requirements."
  • Arrange for on-site service through our field service coordinator at (714) 622-2000. Select the combination of technical expertise and days that may work for you.
  • Coordinate with your instrument users and arrange for workspace on the appointed days. Host FLW technicians, make security arrangements and stage the instruments for calibration. Our calibration technicians will need a clean, well-lit area with 110VAC electrical power and stable temperature conditions. Shutdown and breakdown the instruments as necessary for calibration and provide access to FLW personnel.
  • Access to instruments should be arranged with the instrument users, including any lockout tagout requirements, and a point of contact to supply the instruments to the technicians for calibration during the day(s).
