4.2 Connecting Test Leads
Proper connection of test leads is crucial for accurate and safe measurements.
- Insert the black test lead into the COM (Common) input jack.
- For most voltage, resistance, continuity, diode, capacitance, and frequency measurements, insert the red test lead into the VΩmA input jack.
- For current measurements (up to 10A), insert the red test lead into the 10A input jack.
- Ensure connections are firm before proceeding with measurements.

5. Operating Instructions
5.1 Power On/Off
Press and hold the power button to turn the multimeter on or off. The device features an auto-shutdown function to conserve battery life after a period of inactivity.
5.2 Smart Mode (AUTO)
The KM601s defaults to Smart Mode, which automatically identifies and measures AC/DC voltage, resistance, and continuity. This mode simplifies operation for common tasks.
- In Smart Mode, simply connect the test leads to the circuit or component you wish to measure. The multimeter will automatically detect the type of measurement and display the reading.
- Smart Mode also supports automatic detection for temperature, live wire, flashlight, diode, capacitance, and frequency/duty cycle.

5.3 Manual Mode and Specific Measurements
For specific measurements or when Smart Mode cannot determine the correct function, you can manually select the desired mode using the AUTO/FUNC button.
- Voltage (AC/DC): Press AUTO/FUNC until the voltage symbol (V~ or V-) appears. Connect test leads in parallel to the circuit.
- Resistance (Ω): Press AUTO/FUNC until the Ω symbol appears. Connect test leads across the component. Ensure the circuit is de-energized.
- Continuity: Press AUTO/FUNC until the continuity symbol (speaker icon) appears. A beep indicates continuity.
- Current (A): Switch the red test lead to the 10A jack. Press AUTO/FUNC until the current symbol (A~ or A-) appears. Connect the multimeter in series with the circuit.
- Capacitance (F): Press AUTO/FUNC until the F symbol appears. Connect test leads across the capacitor. Ensure the capacitor is discharged.
- Diode Test: Press AUTO/FUNC until the diode symbol appears. Connect test leads across the diode.
- Frequency/Duty Cycle (Hz/%): Press AUTO/FUNC until Hz or % appears.
- Temperature (°C/°F): Connect the thermocouple to the appropriate input jacks. Press AUTO/FUNC until °C or °F appears.
- NCV (Non-Contact Voltage): Select NCV mode. Hold the top of the multimeter near a live wire. The device will beep and flash if voltage is detected.
- Live Wire Detection: Select Live mode. Use the red test lead to detect live wires.

7. Troubleshooting
If you encounter issues with your KAIWEETS KM601s, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low or depleted battery. | Charge the multimeter using the provided cable. |
| No reading or incorrect reading. | Incorrect function selected; poor test lead connection; damaged test leads; circuit not energized (for voltage); component faulty. | Verify function selection (Smart Mode or Manual); ensure test leads are firmly connected; check test leads for damage; confirm circuit status; test component separately. |
| Current measurement not working. | Red test lead in wrong jack; blown fuse. | Ensure red test lead is in the 10A jack; check and replace fuse if necessary (consult a professional). |
| Display is dim or flickering. | Low battery. | Recharge the multimeter. |
| Auto-shutdown occurs too quickly. | Default setting. | This is a power-saving feature. The auto-shutdown time is typically fixed and cannot be adjusted. |
