ESG-400
2-6 Checking the patient leakage current (according to IEC 60601-1)
NOTE
For this test an interconnection of the three receptacles of MONOPOLAR 1
and MONOPOLAR 2 is
allowed. Before interconnect the three receptacles
verify, that the safety test function is activated and the button “Relays on” is
marked white.
1) Switch the electrosurgical generator on and activate the safety test function in the service menu (see
chapter 8-2, Safety Test) and verify that the button “Relays on” is marked white.
2) Connect the UNIVERSAL cable (J008) to the UNIVERSAL socket and the connection cable P-cord (J011)
to the neutral socket.
3) Connect two 4mm cables “banana” (J007) to every receptacle of the BIPOLAR socket.
4) Connect three 4mm cables “banana” to the 4mm receptacles of the MONOPOLAR 1 socket. Leave the
8 mm BOVIE connector open.
5) Connect three 4mm cables “banana” to the 4mm receptacles of the MONOPOLAR 2 socket. Leave the
5/9 mm ERBE connector open.
6) Verify again that the Button “Relays on” at the touch screen is marked white and short circuit all
connectors.
7) Switch the electrosurgical generator off, cable it with the electrical safety tester (J001) according to the
tester’s instructions for use and switch it on again. Start the test with the electrical safety tester according
to the tester’s instructions for use.
8) Verify under normal condition (NC) for AC the patient leakage current is ≤ 0.01 mA.
9) Verify under normal condition (NC) for DC the patient leakage current is ≤ 0.01 mA.
10) Verify under single fault condition (SFC, “open earth”) for AC the patient leakage current is ≤ 0.05 mA.
11) Verify under single fault condition (SFC, “open earth”) for DC the patient leakage current is ≤ 0.05 mA.
12) Disconnect all cables from the electrosurgical generator.
13) Deactivate the safety test function in the service menu.
14) Record the test results in the Inspection Card (see chapter 5-3).
