11.0 Limited Warranty
The Bios DryCal DC-Lite is warranted to the original end user to be free from
defects in materials and workmanship under normal use and service for a period
of one year from the date of purchase as shown on the purchaser’s receipt. The
DC-Lite’s battery is warranted for 6 months from the original purchase date. If the
unit was purchased from an authorized reseller a copy of an invoice or packing
slip showing the date of purchase may be required to obtain warranty service.
The obligation of Bios International Corporation under this warranty shall be
limited to repair or replacement (at our option), during the warranty period, of any
part which proves defective in material or workmanship under normal use and
service provided the product is returned to Bios International Corporation,
transportation charges prepaid.
Notwithstanding the foregoing, Bios International Corporation shall have no
liability to repair or replace any Bios International Corporation product:
1
Which has been damaged following sale, including but not limited to damage
resulting from improper electrical voltages or currents, defacement, misuse,
abuse, neglect, accident, fire, flood, act of God or use in violation of the
instructions furnished by Bios International Corporation,
2
When the serial number has been altered or removed or
3
Which has been repaired, altered or maintained by any person or party
other than Bios International Corporation’s own service facility or a Bios
authorized service center.
This warranty is in lieu of all other warranties, and all other obligations or liabilities
arising as a result of any defect or deficiency of the product, whether in contract or
in tort or otherwise. All other warranties, expressed or implied, including any
implied warranties of Merchantability and fitness for a particular purpose, are
specifically excluded.
In no event shall we be liable for any special, incidental or consequential damages
for breach of this or any other warranty, express or implied, whatsoever.

10.0 Calibration Statement
Calibration refers to a set of operations that establish, under specified conditions,
the relationship between the values of a quantity indicated by a measuring
instrument (the device under test, such as your DC-Lite) and the corresponding
values of a standard. In other words, to calibrate is to check, or determine, the
validity of a measuring instrument by comparison with a standard. Calibration
may also include adjustment to restore the device under test to its original
specification, although adjustment is not possible with a DryCal, because of its
primary nature: the dimensional characteristics of the flow cell do not change over
time. At Bios, calibration of your DryCal DC-Lite is a comparison against our
laboratory standard, which is a primary piston prover of similar operating
principals to your DC-Lite.
Bios is an ISO-17025 accredited laboratory. ISO 17025 is the ISO standard
(International Organization for Standardization) specifically designed to assess the
competence of testing and calibration facilities. The requirements of ISO 17025
encompass all aspects of laboratory management, including calibration
procedures, analytical testing proficiency, report generation and record keeping,
and ensure calibrations are performed by properly-trained personnel using
controlled test methods and procedures. All ISO 9000 elements relevant to the
testing and calibration services within a laboratory's quality system are
incorporated in ISO 17025.
Upon arrival at Bios and prior to shipment from Bios, your DC-Lite is dynamically
tested by comparing it to our laboratory piston prover of at least 4x greater
accuracy (±0.25% volumetric), the 4:1 ratio recommended by the
GUM
(
International Guide to the Expression of Uncertainty in Measurements
). We use
a stable, triple-regulated flow source of ±0.01% stability (factored into the prover's
accuracy) running from high-purity bottled nitrogen.
Our piston prover standard is qualified by direct measurement of its dimensions
(dimensional calibration): diameter of the piston and glass assembly, length of
measured path, and time, against NIST-traceable instruments and gauges. A
rigorous analysis of its uncertainty in accordance with the
GUM
has been
performed, assuring its traceable accuracy. Test procedures ensure temperature
matching of the standard to your DC-Lite. The calibration dates for each parameter
of our standard (diameters, encoder spacing, time base) are included in our
calibration certificates, along with identification of the devices used for calibration,
their calibration dates, and NIST calibration numbers.
