3. Product Features

3.1. TRUE-RMS AC/DC Clamp Meter

This multimeter provides accurate True-RMS measurements for both AC and DC currents and voltages. It is equipped to measure a wide range of electrical parameters, making it suitable for various applications from household electrical systems to automotive and industrial troubleshooting.

3.2. D-Shaped Jaw Design

Unlike traditional clamp meters, the KC604 features a distinctive D-shaped jaw that can open up to 1.1 inches (2.87 cm). This design provides a convenient and secure way to clamp onto various cables, including larger diameter wires, for current measurements.

3.3. NCV (Non-Contact Voltage) Detection

The non-contact voltage testing function allows you to detect AC voltage without direct circuit contact, enhancing safety. Simply press the NCV button and bring the meter close to the conductor. The device provides audible and visual alarms, with the buzzer frequency increasing as the voltage signal strengthens.

3.4. User-Friendly Design

The KC604 is designed with user convenience in mind. It features integrated test lead storage, an LCD backlight screen for clear readings in various lighting conditions, and a built-in flashlight for dimly lit areas. A low battery indicator prompts timely battery replacement, and the ammeter automatically shuts off after 15 minutes of inactivity to conserve power.

4. Setup

4.1. Battery Installation

1. Ensure the meter is turned OFF.
2. Locate the battery compartment cover on the back of the meter.
3. Use a screwdriver to remove the screw securing the battery cover.
4. Insert the required AAA batteries, observing the correct polarity (+/-) as indicated inside the compartment.
5. Replace the battery cover and secure it with the screw.

4.2. Connecting Test Leads

1. Ensure the meter is turned OFF before connecting or disconnecting test leads.
2. Insert the black test lead into the 'COM' (common) input jack.
3. Insert the red test lead into the appropriate input jack for your measurement:
   • For Voltage, Resistance, Capacitance, Frequency, Diode, and Continuity measurements, insert into the 'VΩHz' jack.
   • For Current measurements using test leads (not clamp), refer to the specific current input jack if available (KC604 primarily uses clamp for current).
4. Ensure connections are firm and secure.

5. Operating Modes

The KAIWEETS KC604 features a rotary dial to select different measurement functions. Turn the dial to the desired function before taking a measurement.

5.1. AC/DC Current Measurement (Clamp)

1. Turn the rotary dial to the '400A' or '40A' AC/DC current range.
2. For DC current measurement, press the 'Z/F' button to zero the data before clamping.
3. Open the clamp jaw and enclose only one conductor (not a bundle of wires) within the jaw.
4. Read the current value on the LCD display.

5.2. AC/DC Voltage Measurement

1. Turn the rotary dial to the 'V~' (AC Voltage) or 'V=' (DC Voltage) position.
2. Connect the red test lead to the positive (+) point and the black test lead to the negative (-) or common point of the circuit.
3. Read the voltage value on the LCD display.

5.3. Resistance, Continuity, Diode, Capacitance, Frequency

These functions are typically grouped on the rotary dial. Select the appropriate symbol for your desired measurement:

• Resistance (Ω): Measures the electrical resistance of a component or circuit.
• Continuity (): Checks for a complete circuit path with an audible beep for low resistance.
• Diode (): Tests the forward voltage drop of a diode.
• Capacitance (): Measures the capacitance of a capacitor.
• Frequency (Hz): Measures the frequency of an AC signal.

Connect the test leads across the component or circuit as appropriate for each measurement type.

6. Maintenance

6.1. Cleaning

To clean the meter, wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents. Ensure the meter is completely dry before use.

6.2. Battery Replacement

When the low battery indicator appears on the display, replace the batteries promptly to ensure accurate readings. Follow the battery installation steps in Section 4.1.

6.3. Storage

When not in use for extended periods, remove the batteries to prevent leakage. Store the meter and its accessories in the provided carry case in a cool, dry place, away from direct sunlight and extreme temperatures.

7. Troubleshooting

• Meter does not turn on or display is blank: Check battery installation and ensure batteries are not depleted. Replace if necessary. The auto-off feature may have activated; simply turn the dial or press a button to reactivate.
• Inaccurate readings: Ensure the correct measurement function is selected. Check test lead connections for firmness. Verify that the D-shaped jaw is properly closed around a single conductor for current measurements.
• Continuity function does not beep: Ensure the test leads are making good contact with the circuit. The resistance may be too high for the continuity function to register.
• NCV detection not working: Ensure the NCV function is selected and the top of the D-shaped jaw (where the sensor is located) is pointed towards the AC voltage source.
