2. Safety Information

To ensure safe operation and avoid damage to the meter, please observe the following safety precautions:

• Always adhere to local and national safety codes.
• Do not exceed the maximum input values specified for each function.
• Ensure the test leads are properly connected and the function switch is set to the correct range before making any measurements.
• Do not use the meter if it appears damaged or if the insulation on the test leads is compromised.
• Exercise extreme caution when working with voltages above 30V AC RMS, 42V peak, or 60V DC. These voltages pose a shock hazard.
• Replace the battery immediately when the low battery indicator appears to ensure accurate readings.
• Do not operate the meter in explosive gas, vapor, or dust environments.
• Always disconnect power to the circuit and discharge all high-voltage capacitors before measuring resistance, continuity, diodes, or capacitance.

4. Setup

4.1 Battery Installation

The GOLDEN BLUE 616 Multimeter requires two AAA batteries (not included) for operation.

1. Ensure the multimeter is powered off.
2. Locate the battery compartment on the back of the device.
3. Use a screwdriver to open the battery compartment cover.
4. Insert two AAA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
5. Replace the battery compartment cover and secure it with the screw.

4.2 Connecting Test Leads

Always connect the test leads correctly before making measurements.

• Insert the black test lead into the COM (Common) input jack.
• For most measurements (voltage, resistance, capacitance, frequency, diode, continuity), insert the red test lead into the Positive Input jack.
• For current measurements (AC/DC Current up to 10A), insert the red test lead into the 10A Input jack.

5. Operating Instructions

The GOLDEN BLUE 616 features automatic recognition for most measurement types. Long press the red power button to turn on the device.

5.1 AC/DC Voltage Measurement

1. Connect the black test lead to COM and the red test lead to the Positive Input jack.
2. Turn on the multimeter. The device will automatically enter auto-ranging mode.
3. Touch the test probes to the circuit points where you want to measure voltage.
4. The display will show the AC or DC voltage reading. Use the SELECT button if you need to manually switch between AC and DC modes in some auto-sensing scenarios.

5.2 AC/DC Current Measurement (up to 10A)

1. WARNING: Never connect the test leads in parallel across a voltage source when measuring current. This can blow the fuse or damage the meter.
2. Connect the black test lead to COM and the red test lead to the 10A Input jack.
3. Turn on the multimeter.
4. Open the circuit where you want to measure current.
5. Connect the test probes in series with the circuit.
6. The display will show the AC or DC current reading. Use the SELECT button if needed.

5.3 Resistance Measurement

1. Connect the black test lead to COM and the red test lead to the Positive Input jack.
2. Ensure the circuit or component is de-energized and all capacitors are discharged.
3. Touch the test probes across the component to measure its resistance.
4. The display will show the resistance value in Ohms (Ω), Kilo-ohms (kΩ), or Mega-ohms (MΩ).

5.4 Capacitance Measurement

1. Connect the black test lead to COM and the red test lead to the Positive Input jack.
2. WARNING: Ensure the capacitor is fully discharged before measurement to prevent damage to the meter or personal injury.
3. Touch the test probes across the capacitor terminals.
4. The display will show the capacitance value in Farads (F), microfarads (µF), or nanofarads (nF).

5.5 Diode Test and Continuity

1. Connect the black test lead to COM and the red test lead to the Positive Input jack.
2. Ensure the circuit or component is de-energized.
3. For Diode Test: Touch the red probe to the anode and the black probe to the cathode of the diode. The display will show the forward voltage drop. Reverse the probes; the display should show "OL" (Open Line) for a good diode.
4. For Continuity Test: Touch the probes across the component or wire. A continuous beep indicates continuity (low resistance).
