4. Setup
4.1 Battery Installation (KC602)
- Ensure the clamp meter is powered off.
- Locate the battery compartment on the back of the device.
- Open the compartment cover.
- Insert the required batteries (typically AAA, check device markings) observing correct polarity.
- Close the battery compartment securely.
4.2 Connecting Test Leads (KET20)
- Ensure the clamp meter is powered off.
- Insert the red test lead's banana plug into the "VΩHz" input jack on the clamp meter.
- Insert the black test lead's banana plug into the "COM" input jack on the clamp meter.
- Ensure the connections are firm and secure.
5. Operating Instructions
5.1 Power On/Off
Press the power button (⏻) to turn the device on. The intelligent mode will activate by default. Press and hold the power button to turn off the device.
5.2 Intelligent Mode Operation
In intelligent mode, the KC602 automatically detects and measures AC/DC voltage, resistance, and continuity. Simply connect the test leads to the circuit or component to be measured.
5.3 Function Selection
Press the "SELECT" button to cycle through different measurement functions (e.g., Capacitance, Diode, Temperature, NCV, Live Wire, Inrush Current) if not automatically detected by intelligent mode.
5.4 AC/DC Voltage Measurement
- Turn on the meter. It will likely default to intelligent mode.
- Connect the red test lead to the positive terminal and the black test lead to the negative terminal or ground of the circuit.
- Read the voltage value on the display.

5.5 AC/DC Current Measurement (Clamp Function)
- Turn on the meter and select the current measurement mode if not in intelligent mode.
- Open the clamp jaws by pressing the trigger.
- Enclose only one conductor (wire) within the clamp jaws. Do not clamp around multiple wires carrying current in opposite directions, as this will result in an inaccurate reading.
- Close the clamp jaws securely.
- Read the current value on the display.
5.6 Inrush Current Measurement
The KC602 can measure inrush current, which is the maximum instantaneous input current drawn by an electrical device when first turned on. The measurement range is 5-600A.
- Select the Inrush Current mode using the SELECT button.
- Clamp the meter around the single conductor of the device to be tested.
- Turn on the device. The meter will capture and display the peak inrush current.

5.7 NCV (Non-Contact Voltage) Detection
The NCV function allows for detection of AC voltage without direct contact. Select NCV mode and bring the top of the clamp meter near the conductor. The meter will indicate the presence of AC voltage with an audible beep and/or visual indicator.
5.8 Data Hold (HOLD)
Press the "HOLD" button to freeze the current reading on the display. Press it again to release the hold function.
5.9 MAX/MIN Function
Press the "MAX/MIN" button to record the maximum and minimum readings during a measurement session. Press again to cycle through MAX, MIN, and current readings.
6. Maintenance
6.1 Cleaning
Wipe the meter and test leads with a damp cloth and mild detergent. Do not use abrasive cleaners or solvents. Ensure the device is completely dry before storage or next use.
6.2 Battery Replacement
When the low battery indicator appears on the display, replace the batteries promptly to ensure accurate readings. Refer to section 4.1 for battery installation instructions.
6.3 Storage
Store the device and test leads in a cool, dry place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Meter does not power on. | Dead or incorrectly installed batteries. | Replace batteries, ensuring correct polarity. |
| Inaccurate readings. | Incorrect function selected; damaged test leads; external interference. | Verify function mode; inspect test leads for damage; move away from strong electromagnetic fields. |
| No continuity beep. | Circuit is open; continuity mode not selected. | Ensure circuit is closed; select continuity mode. |
| Display shows "OL" (Overload). | Measurement exceeds range. | Ensure the measured value is within the meter's specified range for the selected function. |
