YF-78 LCR Multimeter
Application
Easy for holding according to the best design to fit human body engineering, with the optimum inclined view angleFeatures
Specifications
Display unit: 3½digits LCD, with a maximum reading of 1999, units. decimal point and symbol display.
Polarity Indication: when negative value input, automatic display the symbol "-".
Zero reset adjustment: automatic zero reset.
Overload indication:LCD will show a "OL".
Low battery indication: automatic low power test, when battery voltage is lower than work voltage, "BAT" will be shown and you should be ready to replace a new battery.
Sampling rate: 2.5 times/sec.
