  • Page 17 The Test Sequence 1: Visual Check The visual check feature is included to enable the user to record the fact that the unit has been physically inspected for defects. There are three main inspection points - case, lead & fuse. For each of these three inspection categories, the tester will prompt the user for confirmation of a pass or fail result.
  • Page 18 The Test Sequence 3: Insulation Test If selected in the test settings, the Insulation Test will be performed. The test applies 250V or 500V to Live & Neutral with respect to Earth. The protective insulation between Live / Neutral and Earth is then measured and displayed in MΩ.
  • Page 19 The Test Sequence Depending on test selection, the Flash test is performed at either 1250Vac or 2500Vac. For Metal Cased products, the test is performed at 1250Vac. The test voltage will be displayed at the top of the screen. If testing a Double Insulated product, use the Flash probe and apply it to a suitable test point on the product under test.

    Safety Tests during operation --------------------WARNING-------------------- INTERNAL RELAY FAULT.CANNOT PROCEED. If this message is displayed then the Safe Check 8 is faulty and should be returned to your Clare agent for repair. Safety Tests during operation The Tester performs self-tests during normal operation. An internal Earth Bond test and a low voltage test are performed prior to applying mains power to any EUT (including Leakage tests).

  • Page 37: Multiple Earth Connections

    This has previously needed the additional Earth connections to be isolated. The Safe Check 8 tester is capable of testing Earth connections in the presence of additional Earth paths. This is done automatically by performing a point-to-point measurement of the Earth connection, and measurement of the differential leakage current, rather than the Earth lead current.

  • Page 46: Appendix A Purpose Of Tests

    Appendix A Purpose of Tests Earth Bond Test This test is to ensure that the connection between the Earth pin in the mains plug of the appliance and the metal casing of the appliance is satisfactory and of sufficiently low resistance. A selectable test current is applied between the Earth pin of the mains supply plug and the Earth Bond test lead clip.
  • Page 47 Appendix A Purpose of Tests For appliances which incorporate over-voltage protection, a 250V DC test voltage is provided to allow a reading to be taken without the protection devices generating a false failure. Short to Case Test The Short to Case test applies a nominal voltage of 40V AC RMS to the appliance and is applied between the Earth pin and both the live and neutral pins of the supply plug.
  • Page 48 Appendix A Purpose of Tests IEC Lead Test This test confirms the electrical safety of 230V IEC leads. The IEC test performs a continuity and polarity check on the Live and Neutral conductors and confirming that there are no breaks or cross wiring in these conductors.
  • Page 49 Appendix A Purpose of Tests Leakage Test The Leakage Test shows the current being lost through Leakage as the difference in the currents flowing in the Live and the Neutral conductors. This difference is the total leakage away from the appliance, and is generally equivalent to the current flow through the Earth lead of the appliance, and displays the result in milliamps (mA).
