Monitor Testing
If the monitor fails any portion of these tests contact the Criticare
Service Department for additional information. See “Functional and
Safety Testing” in Section 5 for functional and electrical safety tests.
Monitoring module verifications are also located in “Service Checks”
in Section 5.
Service Checks
If the monitor shows any signs of physical damage return it to
Criticare for repair.
• If the unit fails any tests, contact Criticare. Do not use the
monitor for patient monitoring until you fix the problem.
• No user-serviceable parts exist inside the monitor. Do not
remove the cover. Refer all servicing to a qualified technician.
Field Service Testing
• Service testing procedures require working with exposed
electrical circuits and only experienced electrical or biomedical
technicians should attempt these procedures.
• Any time a monitor is altered through repair or hardware
adjustment, you should fully test it before use.
• Always follow ESD precautions when you perform any of the
procedures discussed in this section.
• The manufacturer recommends that a serviced monitor be
allowed to run for 24 hours before you place the monitor back
into operation.
• Modules and PCBs that you have repaired may require more
extensive testing than what is described in this manual.
The following tests are designated for monitors that require service
repairs. Opening the monitor may void your warranty, so it is
important to contact Criticare customer service before you attempt
any repair.
The pre-assembly testing of printed circuit boards (PCBs) is not
covered in this manual. Disassembly of surface mounted components
on PCBs in not recommended. Tests provided here are only for the
identification of damaged or degraded PCBs.
