OverviewDT830 digital multimeter is a small digital multimeter with a three-and-a-half-digit LCD display. It can measure AC and DC voltage and DC current, resistance, transistor value, diode conduction voltage and circuit short circuit, etc. A rotary band switch changes the measurement function and range, with a total of 19 gears.The maximum display value of this multimeter is 1999, which can automatically display "0" and polarity, display "1" or "-1" when overloaded, and use the diode gear for short circuit inspection.II. Technical characteristics1.
