Patient Isolation Test

Patient Isolation Test - Overview
To verify proper patient isolation, it is important to run this test following any procedure in
which the monitor is opened.
Warning Failure to run the dielectric test when indicated could cause serious
injury to patients, and could lead to damage to the monitor.
The patient isolation test requires an AC Withstand Voltage (hi-pot) Tester, such as the AR
3605 or equivalent. If this equipment is not available, Welch Allyn can perform the patient
isolation test for you quickly, for a nominal fee.
