The Megger CP5CEIDKIT Kit of 4 Split-Core Self-Identifying 5A AC Current Clamps is designed for use with MPQ1000 and MPQ2000 Power Quality Analyzers as well as the PA9 series. The power quality analyzer (sold separately) will automatically identify the current clamps, recognize their range, and verify that the unit is properly connected. Automatic recognition of the current clamp means never having the unit programmed for an incorrect range.|The CP-5CE-ID-KIT current clamps are powered by the main unit, meaning there is no need for additional connections or batteries. The clamps support the 20A range and each include a 6 ft. (1.82 m) cord.
