Setup

1. Initial Charging

Before first use, fully charge the multimeter using the provided USB charging cable. Connect the USB-C end to the multimeter's charging port (DC5V 2A) and the USB-A end to a compatible power source (e.g., computer USB port, wall adapter). The battery indicator on the display will show charging status.

Operating Instructions

Power On/Off

Press the power button to turn the multimeter on or off. The device features an auto-power-off function to conserve battery life if inactive for a period.

Function Selection

Use the function buttons on the top panel to select the desired measurement mode (e.g., AC/DC Voltage, Resistance, Capacitance, Frequency). The large LCD will display the selected mode and measurement results.

Voice Broadcast Function

To activate voice broadcast, press the dedicated voice broadcast button (often integrated into the test lead or on the unit itself). The multimeter will audibly announce the current measurement value. Release the button to stop the broadcast. This feature is particularly useful when visual access to the display is limited.

Bluetooth Speaker Operation

The Zoyi 5566SE features a built-in Bluetooth speaker. To connect, ensure the multimeter is powered on. On your mobile device, search for "DMM music" in your Bluetooth settings and pair. Once connected, you can play audio through the multimeter's speaker. The speaker is located on the side of the unit.

Measurement Examples

• Voltage Measurement: Select AC V or DC V mode. Connect test leads in parallel to the circuit.
• Resistance Measurement: Select Ω mode. Ensure circuit is de-energized. Connect test leads across the component.
• Capacitance Measurement: Select F mode. Ensure capacitor is discharged. Connect test leads across the capacitor.
• Frequency Measurement: Select Hz mode. Connect test leads to the signal source.
