 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
