    In order to mitigate the risk, the high voltage energy limit of the CH2 is 35 mJ and the high voltage charge limit is 45μC. These limits prevent circuits energized during high voltage testing from meeting the definition of hazardous or dangerous live points found in international standards.

  • Page 5: High Voltage Safety

    High Voltage Safety The restricted high voltage energy and charge limits of the CH2 do not mean that performing hipot testing with the system is entirely without risk as operators can still receive a startling or even painful shock. Therefore, it’s necessary and prudent to protect operators. Consider the following while recognizing it is not an exhaustive list.

    Cirris support personnel, you may need to send the affected module or the entire tester back to Cirris for repair. If needed during the repair period, a loaner tester can be sent to you. You should not attempt to service any circuit board at the component level. All component-level service should be performed by Cirris technicians.

    Digital I/O connector Note: CH2 testers made after March of 2007, have HV interlock capability. An interlock helps protect operators from high voltage during the high voltage test. For more information on interlocks, search the word “interlock” in the Easy-Wire help system.
  • Page 14 The power supply auto adjusts to line voltages of either 120 VAC 60 hertz or 240 VAC 50 hertz. For optimum measurement accuracy, the CH2 must have a consistent earth ground to the entire system. Make sure to use a grounded (3- prong) outlet or plug strip.

  • Page 26: Building Fixturing For Fast Attach

    When to build fixtures Best practice is to build the mating fixture connecting the device-under-test (DUT) to the tester before creating the Test Program used for the test setup. Why? If you use Defined Connectors you can create connector and pin documentation by probing the pins of the fixture’s connectors while the fixture is attached to the tester, greatly speeding up test creation.

  • Page 27: Requirements For Using Fast Attach

    Requirements for using Fast Attach Fixture connectors that mate to the device-under-test must be wired in the same relative pattern to the system pins of the tester’s scanner connectors. What makes Fast Attach Connector Types different than the others? A Fast Attach Connector Type requires one more step in its construction, which is to set a wiring pattern describing the relative position of its pins to the pins on the scanner connectors of the tester.

    In order to fixture four-wire to the CH2, the two wires in each 4-Wire Pair must connect to two different kinds of test points called Visible and Hidden. Each Visible point has one specific Hidden mate and the two must go together.
  • Page 30 Mapping the Visible points to Hidden mates From any visible point, the next vertical point is its hidden pin mate. Now that you have built your fixturing, you are ready to Define Four Wire Connectors in the Easy-Wire software. Refer to the online manual/help system for more information on setting up a four-wire test program.
