Casella CEL Defender 510/520 flow calibrator - Manual (Page 8)


Recertification
Your Defender is a precision measuring standard with moving parts machined to extremely close tolerances.
Various environmental factors, product wear, drift of the temperature sensors and pressure transducers used
for recording ambient calibration conditions (Defender 520), or inadvertent damage may adversely affect your
Defender’s measurement accuracy or general
performance.
For these reasons, Bios highly recommends having your Defender annually verified by an ISO 17025–accredited
laboratory, such as Bios, to ensure its measurement integrity. For those applications subject to regulatory or ISO
requirements, verification by a laboratory accredited to the international calibration standards set by ISO provides
you with assurance of measurement integrity and a defensible audit trail in the event of litigation.
For the ultimate in Defender maintenance and to take advantage of any available software and mechanical upgrades,
Bios offers an elective Recertification program. This is a complete product service package that provides pre-cali-
bration; complete product refurbishment, testing and available upgrades; post-calibration; and NIST-traceable, ISO
17025–, ANSI Z-540– and NIST Handbook 150–backed calibration certificates. Recertification includes a 90-day service
warranty should any related labor or parts replacements prove faulty.
Turnaround time is generally two weeks from time of receipt. For an expedite fee, we will place your Defender “next on
bench” for 48-hour turnaround. This means that a Defender received on Monday will be return-shipped on Wednesday,
and a Defender received on Friday will be return-shipped on Tuesday. For a detailed explanation of the 48 hour
process and to obtain current pricing for Recertification, please contact Bios at 973.492.8400 or visit our web site at
www.biosint.com.
Please note that while any ISO 17025–accredited gas flow measurement laboratory may be capable of verifying
the accuracy of your Defender, Bios is the only authorized service center for Bios products. All Defender service
and calibration is performed in our ISO 17025–accredited laboratory in New Jersey by experienced Bios personnel.
Sending Your Defender to Bios
Please contact Bios for an RMA (return merchandise authorization) number before sending your Defender to our factory
for elective Recertification or other service. You can get an RMA number through our automated web-based system at
www.drycal.com/forms/rma.htm, by email to [email protected], or by telephone at 973.492.8400. Our web site address
is www.biosint.com.
Sending your Defender to Bios without an RMA number may result in return of the instrument without inspection or a
substantial delay in service turnaround time.
When requesting an RMA number, provide your Defender model, serial number and revision level. Also describe any
product issues you may be experiencing. Please keep in mind that Bios will not begin evaluation and service of your
Defender until you have accepted and approved, in writing, our formal RMA quote for service. This protects both you
and Bios during this process and ensures a fair and efficient service experience.
If sending your Defender for repair or evaluation (rather than elective Recertification), please contact Bios for
technical support or troubleshooting assistance prior to shipping the unit. We will first attempt to resolve the situation
over the phone or via email. If you’ve provided us with a detailed description of your Defender’s issue and application
details and we’re unable to resolve the situation by phone or email, we’ll issue you an RMA number for prompt return
of your Defender for evaluation.
Please note that Bios will make every attempt to verify your issue, as we want you to get the most out of
your Defender. However, if we are unable to detect a product issue or if we determine that the issue is
application-related rather than product-related, we reserve the right to charge an evaluation fee.
