- Supports 4-electrode method, offering rich measurement functions
- MEC function, can measure without cutting off the grounding electrode
- Dustproof and waterproof IP67, operating temperature -25°C ~ 65°C, drop-resistant
- No need to insert auxiliary grounding rods when using grounding network components
- Shortens operation time, measurement time is only 6 seconds, and test line setup and storage are also easy
- Whether in narrow spaces or on measuring busbars, the current clamp can be easily clamped (optional)
- Supports wireless communication, allowing measurement data to be sent to a smartphone or tablet (when installing optional Z3210)
- Measurement can be done using a clamp sensor (FT6041-91 kit includes 2 clamp sensors)
