ESG-400
2-3 Checking the DC resistance (according to IEC 60601-2-2)
1) Activate the safety test function in the service menu (see chapter 6-1, Safety Test) and verify that the
button “Relays on” is marked white.
2) Connect the digital multimeter (J003) with the bipolar connector on the front panel (see chapter 1-5-2).
3) Verify the resistance is ≥ 2 MΩ.
4) Deactivate the safety test function in the service menu.
5) Record the test results in the Inspection Card (see chapter 5-3).
2-4 Checking the earth resistance (according to IEC 60601-1 and IEC 62353)
1) Connect the electrosurgical generator with an electrical safety tester (J001) according to the tester’s
instructions for use.
2) If the power cord and the electrosurgical unit are measured together, verify the protective earth resistance
≤ 0.3 Ω against metal parts which can be touched.
3) Record the test results in the Inspection Card (see chapter 5-3).
2-5 Checking the earth leakage current (according to IEC 60601-1)
1) Connect the electrosurgical generator with an electrical safety tester (J001) according to the tester’s
instructions for use.
2) Switch on the electrosurgical unit.
3) Verify under normal condition (NC) the earth leakage current is ≤ 0.5 mA.
4) Verify under single fault condition (SFC) the earth leakage current is ≤ 1.0 mA
5) Record the test results in the Inspection Card (see chapter 5-3).
