:: Supports the 4-electrode method with a wide range of measurement functions.
● MEC function allows measurements without disconnecting the grounding pole
● Dust and waterproof IP67, operating temperature -25°C ~ 65°C, drop proof
● The use of grounding grid assemblies eliminates the need to insert auxiliary grounding rods.
:: Reduced operating time, with a measurement time of only 6 seconds and easy setup and stowage of the test line
● Current clamps can be easily clamped whether in confined areas or measuring busbars (option)
● Supports wireless communication for transmitting measurements to a smartphone or tablet PC (when option Z3210 is installed)
:: Clamp sensors can be used for measurements (FT6041-91 set with 2 clamp sensors)
