Service Manual
Criticare Systems, Inc.
Any time you open a monitor’s case you should perform the electrical
safety tests before you return the monitor to operation. If you serviced
the monitor you should also perform the associated functional tests.
Additional tests that are specific to modules and assemblies you
should perform when you service, adjust, calibrate, or otherwise
disassemble any assemblies. See the following table.
Equipment and Tools
The following procedures assume that the technician has available an
ESD safe workbench, a set of electronic hand tools, and a digital
multimeter with a 10-amp setting. Servicing of the NIBP module
requires a calibration work station. At the beginning of each test
special equipment may be listed. A variety of customized cables,
clips, and test fixtures may also be needed to complete all the tests.
Contact Criticare Service for additional information.
