Product features
1. Wide grounding circuit resistance measurement range (0-1200Ω), can meet most of the user's measurement requirements;
2.32mm tongs, can test various ground level and equipotential bus;
3. Ac current measurement range 0-20A, and can be detected below 300mA leakage current, without disconnection can be measured, very suitable for system fault diagnosis;
4. User-defined HI/LO alert limits;
5. Data hold function for obtaining stable readings in inaccessible ces;
6. Time-saving storage function is convenient for users to consult test data after measurement and draw form reports;
7. With CAT III 300V safety rating
