Standardized testing according to IEC 62305-3

IEC 62305-3 describes repeat testing for arresters.

Standard-compliant testing and documentation

In accordance with 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 CHECKMASTER's method of operation meets these requirements.

  • The CHECKMASTER stores all test results in an internal memory
  • The stored test values can be output immediately or at a later time
  • The test report contains the order designation and the test result together with the date and time
  • Data transfer to the PC or printer is through an RS-232 interface
  • The interface also enable contents of the memory to be exported, to an Excel worksheet for example
  • For PCs without a serial interface, an adapter cable is available for connecting to the USB interface
