JASO D001-94 プラグインタイプ
  • Unit compliant with JASO D001-94 standard

JASO D001-94 pulse unit

  • JASO standards are automotive standards established by the Society of Automotive Engineers of Japan. For environment tests, “D001: General Rules of Environmental Testing Methods for Automotive Electronic Equipment” is most generally utilized. Pulse units for performing “transient voltage characteristics tests” in this standard are available as an option. This pulse unit can perform tests conforming to JASO D001 standards by connecting to mainframe KES7702/KES7703 testers.
  • Replacing a pulse unit makes it easy to comply with JASO standards.
  • Recurrence interval: Settings from a minimum of 5.0s are possible.

Application Software

  • the arbitrary waveform generation function

KES7100 – Application Software for KES7000 system

  • Up to 50 test conditions can be registered in a test execution list, and tests are carried out in accordance with the list.
  • For transient surge testing, up to seven types of pulse modules can be controlled.
  • For voltage variations testing, up to four testers can be controlled for synchronous operation by communicating with a single tester.
  • The result of the OK/NG judgment that the user makes at the end of each test can be saved in the execution list.
  • The created test execution list can be saved in a file along with comments.
