Kewtech FC2000 Calibration Checkbox
This calibration checkbox is used for evaluating the overall accuracy of various 17th edition testers during the time period between official calibrations by a certified laboratory.
Encased in its own protective carrying case with a handle, the Kewtech FC2000 is easy to port around from test to test. Inside the case the main unit includes multiple ports for various plug types and can be used to carry evaluations of test lead nulling point, continuity, insulation, loop impedance and RCD testing.
The FC2000 includes three continuity test points, three insulation test points and two loop impedance test points plus local loop.
