It is a portable notebook autoranging digital multimeter with stable performance, high precision and low consumption. It can automatically identify AC/DC voltage, frequency, duty cycle, resistance, capacitance, diode forward voltage drop and on-off test. (The UA16 can not be used for measuring the frequency, duty cycle, and capacitance.)
Features:
100% Brand new and high quality.
Automatically identify AC/DC voltage, frequency, duty cycle, resistance, capacitance, diode forward voltage drop and on-off test, easy to use.
Perfect measuring instrument for the majority of users.
Digital easy-to-read large LCD display.
Low battery indication and Overload protection.
Auto sleep mode for saving power after 30 minutes with no action.
