9.7 Calibration
As a quality assurance measure, Bios recommends annual calibration of all
DryCals, although how often you have your DryCal calibrated is an internal quality
control decision. The determining factors are whether the unit passes the internal
leak-test, quality system requirements if applicable, and the conditions in which
the unit is used. Units used in a laboratory setting may require calibration less
frequently than a unit that is used in a dusty environment.
The annual calibration program is an elective and is therefore not included as
a warranty item. Called “Recertification”, our program includes pre flow data,
product refurbishment, post flow data, and a Calibration Certificate. Please contact
the factory for more information on available calibration services and pricing.
Calibration Includes
• Clean flow cell and piston
• Valve mechanism adjustment (as required)
• Change inlet filter (as required)
• Battery capacity test
• Performance test
• 3-point "As-Received" and "As-Shipped" flow data
• NIST-Traceable Calibration Certificate

9.3 Air Containing Particulates
As of January 1, 2001, the DryCal DC-Lite includes either a 5-micron or 30-micron
inlet filter inside the inlet fitting (depending on model ordered). Older DC-Lites sent
to Bios for calibration will be retrofitted with these inlet filters, free of charge.
However, air containing cigarette smoke, excessive dust, or other particulates
should be additionally pre-filtered. A particulate filter, part AF-516, is available for
this purpose. The filter should be placed ahead of the DryCal in the flow stream, on
the inlet side.
9.4 Return Authorization
Before sending your DryCal to Bios for maintenance, please contact Bios for
technical support, troubleshooting assistance and an RMA number if necessary.
Any DryCal maintenance must be performed by Bios personnel in Bios’
New Jersey facility
You can telephone Bios at (800) 663 4977 or (973) 492 8400, or send an email to
service
@drycal.com.
9.5 Shipment
When shipping the DryCal DC-Lite please ensure that the packaging is adequate
to protect the instrument. When possible the DC-Lite should be shipped in
the original packaging. Bios International Corp. is not responsible for damage that
occurs during shipment.
9.6 Long-Term Storage
DryCal calibrators can remain on charge until needed without causing damage
to the battery. If the DryCal is stored for long periods of time the battery should be
charged at least once every three months.
Always store DryCal calibrators in a clean, dry environment and recharge
the unit prior to use after long-term storage.
