FEATURES
· Stable measurement results can be obtained under a noisy environment by introducing the FFT (Fast Fourier Transform) technology.
·LCD display
· Backlight function to view the test results in dimly areas
· Rk Function is available to cancel the residual resistance on the Test Leads.
· Battery Check Function
· Auxiliary Earth Resistance Measurement Function
Auxiliary earth resistances are measured and displayed.
· 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.
· Auto-Power-Off Function
The instrument is automatically powered off when 5 min passes without any Key operation.
· Data storage
Save 1000 test data
