The test device or loop resistance measuring device is used for contact-free testing of the earthing resistance in electrical systems.
The tester with self-luminous inverse LC display, simultaneously shows resistance (0.
010 - 1200 ohms) and alternating current (0.
00 mA - 20.
0 A) and has a measurement data memory, adjustable alarm function when the limit is exceeded, an automatic switch-off and a data hold function.
The robust device has a large measurement range with high resolution, an exact, reliable and stable power and a high noise immunity.
The tester is microprocessor-controlled and allows accurate earth resistance measurement.
The integrated filter technology effectively minimizes measuring interferences.
The design of the product complies with protection class 2 and is double or reinforced insulated.
