Safety Tests
Use the following safety test procedures to verify safe installation or service of the
monitor. The setups and the acceptable ranges of values used for these tests are
derived from local and international standards, but may not be equivalent. These tests
are not a substitute for local safety testing where it is required for an installation or a
service event. If you use the Metron Safety tester, perform the tests in accordance with
your local regulations. For example, in Europe, use IEC 60601-1 and in the United
States, use ES 60601-1. The Metron Report should print results with the names listed
below, together with other data.
Note — Safety tests meet the standards of, and are performed in accordance with
IEC 60601-1, Clause 8 (EN60601-1).
The monitor safety tests include:
• Ground integrity
• Touch leakage — 4 parts
• Patient leakage current with mains voltage
To perform these tests, you need one of the following:
• Multimeter with a leakage network
• Product safety analyzer
Ground Integrity Testing
Figure 2-1 S(1) Protective Earth Continuity
Expected Test Results:
With mains cable, maximum impedance x 200 mOhms (IEC 60601-1 and ES 60601-1)
This measures impedance of Protective Earth (PE) terminal to all exposed metal parts
of Instrument under Test (IUT), which are for safety reasons connected to the
Protective Earth (PE). Test current 25 Amp applied for 5 to 10 seconds.
