About this item Brand-new Smart+Automatic range dual mode design digital multimeter.Smart mode:Smart judgment of AC/DC voltage, ohm,Continuity measurement without turning the knob. Automatically determine the range of measurement values during measurement. Accurate measurement: AC voltage (60mv~750V),DC voltage (60mv~1000V),AC/DC current (60.00mA~10A),resistance (600.0 ~60.00M ),capacitance (9.999nF~9.999mF),frequency (99.99Hz~9.999MHz),duty cycle(1%~99%),temperature (-20~1000 ),diode output voltage can light up LED lights,continuous measurement resistance needs to be less than 50,Accuracy range: 0.5-1.5%,resolution: 0.1-0.001. Multimeter tester with data storage, non-contact measurement, automatic shutdown, manually disable the automatic shutdown function, with a 50 * 30mm 6000 counter large reverse display screen,the body is small (12.3 * 6.3 * 2.5 (cm)) and the screen is large, making it easy to carry and read. Non-current mode has AC 550V flameproof protection and double ceramic fuse overcurrent protection. The ABS housing material protects the user from the risk of electric shock,Conform to CAT III 1000V,CAT IV 600V safety level.
