 Digital high megohm tester
 This is a digital high megohm tester that uses a
 high-performance. Low-power-consumption CMOS. 
 A/D converter
 Any of four ranges can be selected with one control switch. And a wide range of measurements is possible from min. 0.01M次 to max. 2000M次

 2000M次=1999M次-10M次
 200M次=199.9M次-1M次
 20M次=19.99M次-0.1M次
 2M次=1.999M次-0.01M次
 ACV=600V
