Operation Instructions of GVDA 113A 2 in 1 Voltage detector Multimeter
Voltage DC or AC/Frequency/Resistance/Measure Continuity >Insert the red test lead into the "INPUT"terminal, black test lead into the "COM"terminal.
>Connect the test leads in parallel to the circuit, power supply, tested resistor The meter automatically ldentify whether it is AC voltage,DC voltage or resistance,and shows the frequency on the screen.
>When resistance is less than 30Q, the buzzer sounds.
> When measuring DC voltage, it can also shows the voltage polarity of the red test lead.
> Read the measurement results from the display.
