The steps used for these tests and the acceptable ranges of values 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.
Protective Earth Resistance
Figure 132 illustrates the protective earth resistance measurement of Efficia DFM100.
Figure 132 Efficia DFM100 Protective Earth Resistance Test Diagram
Acceptable test results:
Maximum impedance x <
100m(IEC 60601-1 and UL 60601-1). Records as “aaa”.
Leakage Currents
Figure 133 illustrates the Efficia DFM100 circuitry.

NOTE: ˙ Check accessible conductive parts for touch current (enclosure leakage current), but not for protective
earth resistance because they are not protectively earthed.
