WARNING - USERS
The DPM-2350 is for use by skilled technical
personnel only.
WARNING - USE
The DPM-2350 is intended for testing only and
should never be used in diagnostics, treatment
or any other capacity where it would come in
contact with a patient.
WARNING - CONNECTIONS
All connections to patients must be removed
before connecting the DUT to the DPM-2350. A
serious hazard may occur if the patient is
connected when testing with the DPM-2350.
CAUTION - SERVICE
The DPM-2350 is intended to be serviced only by
authorized service personnel. Troubleshooting
and service procedures should only be
performed by qualified technical personnel.
CAUTION - INSPECTION
The DPM-2350 Series Meters should be inspected
before each use for wear and the Meter should
be serviced if any parts are in question.
CAUTION - MODIFICATIONS
The DPM-2350 is intended for use within the
published specifications. Any application
beyond these specifications or any unauthorized
user modifications may result in hazards or
improper operation.
ii
CAUTION - LIQUIDS
Do not submerge or spill liquids on the DPM-
2350. Do not operate the DPM-2350 if it may have
been exposed to fluid.
CAUTION - ENVIRONMENT
Exposure to environmental conditions outside
the specifications can adversely affect the
performance and accuracy of the DPM-2350. If
the unit is outside the Operating Specifications,
allow it to acclimate to specified conditions for at
least 30 minutes before attempting to operate it.
CAUTION - CLEANING
Do not immerse. The Meter should be cleaned by
wiping gently with a damp, lint-free cloth.
A mild detergent can be used if desired.
CAUTION – MEDIA COMPATIBILITY
The DPM-2350 is intended to be used with only
non-corrosive, non-ionic, or otherwise pure
fluids and/or gases that are compatible with
sensor materials including glass, silicon,
ceramic, epoxy, RTV, gold, aluminum and nickel.
CAUTION – LO PRESSURE PORT
LIQUIDS INCOMPATIBILITY
The Lo port of the DPM-2350 is not intended for
liquids, use only dry gases.
