IEC 62305-3 describes repeat testing for arresters.

Standard-compliant testing and documentation

According to IEC 62305-3, surge protective devices must be tested regularly (see table below). In addition, the standard requires the traceable documentation of test values. The method of operation of the CHECKMASTER 2 meets these requirements.

  • CHECKMASTER 2 stores all test results in an internal memory.
  • The stored test values can be output anytime.
  • The test report contains the order designation and the test result together with the date and time.
  • Data transfer to the PC is performed via a USB stick.
  • The log files are saved in CSV format and can be processed further in any spreadsheet application.
