  1. General Description

AM-900/901/902/904 is a digital multimeter  equipped with backlight function (except AM-904) and overiload protection circuit. AM-900, AM-901 and AM-904 has LCD display of 3 ½ digits(2000 counts) while AM-902 has LCD display of 3 ¾ digits (4000 counts). The multeimeter performs AC/DC Voltage, DC Current, Resistance, Audible Continuity, Diode, Transistor detecting, etc.

AM-903 is a digital capacitance meter with 3 ½ digits(2000 counts) LCD backlight display. Made with dual slope integrating converter, AM-903 ranges from 200pF to 20 mF .
