* Multiple parameter measurement: Ra, Rz, Rq, Rt

* Highly sophisticated inductance sensor

* Four wave filtering methods : RC, PC-RC,GAUSS and D-P

* Built-in lithium ion rechargeable battery and control circuit with high capacity

* Can communicate with PC computer for statistics,printing and analysing by the optional cable and the software for RS232C interface.

*Manual or automatic shut down. The tester can be switched off by pressing the Power key at any time.On the other hand, the tester will power itself off about 5 minutes after the last key operation.

*The tester can memorize 7 groups of measurement results and measuring conditions for later use ordownload to PC for analysing, printing.

*Metric /Imperial Conversion
