1. Stable measurement results can be obtained under a noisy environment by introducing the FFT (Fast Fourier Transform) technology.
2. LCD display, backlight function to view the test results in dimly areas
3. Rk Function is available to cancel the residual resistance on the Test Leads.
4. Function: battery check / auxiliary earth resistance measurement / auto-power-off
5. Warning for Auxiliary Earth Resistance Measurements. Warnings are displayed on the LCD when auxiliary earth resistances are too high and may result in inaccurate measurements.
6. The instrument is automatically powered off when 5 min passes without any Key operation.
7. Data storage: save 1000 test data
