Overview
The following information describes the requirements and tests necessary for safety and performance
verification of the monitor.
Caution:
Observe precautions for handling electrostatic-sensitive devices!
Note:
• Never touch electrostatic-sensitive electronic components without following proper anti-static
procedures, including the use of an ESD wrist band and mat. An electrostatic discharge from your
fingers can permanently damage electronic components and cause latent failures.
• All static-sensitive electronic components are packaged in static-shielding bags. Retain the bag for
repackaging the component should you need to store it or return it to Spacelabs Healthcare for any
reason.
• Cleaning, preventive maintenance, and safety checks should be performed annually and following any
product disassembly/assembly. Preventive maintenance and safety checks must be performed by
trained personnel only.
Required Test Equipment
• Electrical Safety Analyzer — Dynatech Nevada 232C or equivalent
• Patient Simulator — Dynatech Nevada 300B or equivalent
Note:
• Before testing, ensure that the module housing(s) and its DC power supply(s) have their associated
cables attached, but are not interconnected.
• Ensure that the Ethernet cable and AC power sources are removed.
• The AC line is auto detected; no user selection is necessary.
• Ensure that the leakage test equipment is calibrated.
