Multiple parameter measurement: Ra, Rz, Rq, Rt

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 analyzing by the optional cable and the software for RS232C interface.

The tester can memorize 7 groups of measurement results and measuring conditions for later use or download to PC.
