Safety tests after repair
ATTENTION!
After every repair or dismantling the enclosure, the autoclave
should pass two safety electrical test by the Service
Engineer. The following shall be performed:
1. Enclosure Leakage Current Test.
Every autoclave should pass this test as follows:
1. Connect the electrical cord to the autoclave.
2. Turn on the main switch on the right side of the autoclave.
3. Short-circuit the L and N pins on the cord's plug.
4. Connect the Short-circuit pins to the L pole on the electrical
tester.
5. Connect the earth pins to the earth pole on the electrical
tester.
6. Impose an electrical potential of 500-1000V on the tested
autoclave. The insulation resistance should be at
least 2 MΩ.
The test is successful if there was no leakage.
2. Protective Earth Impedance Test
1. Connect the grounding pin of the power cord plug to one pole
of an Ohmmeter.
2. Connect any other metallic part (preferable
– the metallic part
of the locking screw) to the second pole of the Ohmmeter.
3.
The resistance should not exceed 0.3 Ω.
After performing these tests, the Service Engineer should
complete and sign the Work Order.
