2. Charging the KM602 Multimeter

The KM602 features a built-in rechargeable battery. Connect the provided USB charging cable to the multimeter and a suitable USB power source. The battery life is designed for extended use, and quick charging ensures the device is ready when needed.

3. Connecting Test Leads

Insert the red test lead into the positive (+) input jack and the black test lead into the common (COM) input jack. Ensure a secure connection before proceeding with any measurements.

Operating Instructions

Both the KM100 and KM602 multimeters offer various measurement capabilities. The KM602 defaults to a SMART mode for simplified operation.

KM602 Smart Mode Operation

In SMART mode, the KM602 automatically identifies and measures AC/DC voltage, resistance, and continuity. This mode automatically selects the optimal range for the highest precision, simplifying the measurement process.

Common Measurement Functions

Both models can precisely gauge a wide range of electrical parameters:

• AC and DC Voltage: Measure voltage in circuits.

• Resistance: Determine the electrical resistance of components.
• Continuity: Check for complete electrical paths.
• AC and DC Current: Measure current flow (KM602 supports AC/DC current, KM100 supports DC current).
• Capacitance: Measure the capacitance of capacitors.
• Frequency: Measure the frequency of AC signals.
• Diode Test: Test the functionality of diodes.
• Duty Cycle: Measure the duty cycle of pulsed signals.
• Temperature: Measure temperature (KM602).
• NCV (Non-Contact Voltage) & Live Wire: Detect live voltage without direct contact for enhanced safety.

Maintenance

Proper maintenance ensures the longevity and accuracy of your KAIWEETS multimeter.

Cleaning

Wipe the device with a dry, clean cloth. Do not use abrasive cleaners or solvents. Ensure the device is powered off before cleaning.

Battery Care (KM602)

To maximize the life of the KM602's rechargeable battery, avoid fully discharging it frequently. Charge the device regularly, especially if it will be stored for an extended period.

Fuse Replacement

The multimeters feature two distinct fuse sizes for safeguarding against overload. If a fuse blows, replace it with a fuse of the exact same type and rating to maintain safety and functionality. Refer to the full manual for specific fuse specifications and replacement procedures.

Troubleshooting

If you encounter issues with your KAIWEETS multimeter, consider the following general troubleshooting steps:

• No Display/Power: Ensure the device is powered on. For KM602, check battery charge level and recharge if necessary. For KM100, check battery installation.
• Incorrect Readings: Verify test lead connections are secure and inserted into the correct input jacks for the desired measurement. Ensure the correct function is selected (or rely on SMART mode for KM602).
• No Continuity Beep: Check if the continuity function is selected and if the circuit is indeed continuous.
• Overload Indication: If the display shows "OL" or an overload symbol, the measured value exceeds the meter's range for the selected function. Switch to a higher range if available, or ensure the measurement is within the device's capabilities.

For more specific troubleshooting or persistent issues, please refer to the detailed troubleshooting section in the complete user manual or contact KAIWEETS customer service.
