According to IEC 62305-3, surge protective devices must be tested regularly. 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 immediately or at a later time.
• The test report contains the order designation and the test result together with the date and time.

Several test sockets are available that can be used for testing virtually all plug-in arresters with the CHECKMASTER 2.

The CHECKMASTER checks surge protective devices from Phoenix Contact according to their specific electrical properties. The acquisition of order numbers is error free with the barcode scanner
. The test object is simply inserted into the associated test adapter. If the scanner has already detected the device type, the test is started automatically upon insertion.
Alternatively, the order number of the test object can be entered via the touch panel after insertion into the test adapter.

Test result

• Status 1: OK
• Status 2: tolerance limit reached
• Status 3: overloaded, replacement required

Tolerance limit reached – replacement recommended

If the CHECKMASTER indicates “Tolerance limit reached”, the arrester has already been subjected to stress several times. Although the surge protective device is still functional, it should be replaced as part of preventive maintenance.
