2. Safety Information

Please read and understand all safety information and operating instructions before using this meter. Failure to follow these instructions could result in electric shock, fire, or serious injury.

• Always ensure the meter is in good working condition before use. Inspect the test leads for any damage.
• Do not apply more than the rated voltage, as marked on the meter, between the terminals or between any terminal and earth ground.
• Use extreme caution when working with voltages above 30V AC RMS, 42V peak, or 60V DC. Such voltages pose a shock hazard.
• Keep your fingers behind the finger guards on the test probes during use.
• Do not use the meter if it is wet or if your hands are wet.
• Ensure the meter is set to the correct function and range before making measurements.
• Disconnect the test leads from the circuit before changing functions.
• Replace batteries immediately when the low battery indicator appears to ensure accurate readings.
• Adhere to local and national safety codes.

4. Specifications

The following table details the technical specifications of the KAIWEETS KC602 Smart Clamp Meter:

5. Setup

5.1 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 open the battery compartment.
4. Insert three (3) AAA 1.5V batteries, observing the correct polarity (+ and -).
5. Replace the battery compartment cover and secure it with the screw.

5.2 Initial Power-On and Self-Test

1. Press the Power button to turn on the meter.
2. The meter will perform a self-test, indicated by a 'CAL' display, ensuring all functions are ready.
3. After the self-test, the meter will typically enter 'SMART' mode, automatically recognizing measurement signals.

Figure 5.1: The meter performs a self-test upon power-on and then enters Smart Mode for automatic signal recognition.

5.3 Connecting Test Leads

• For voltage, resistance, capacitance, diode, and continuity measurements, insert the black test lead into the 'COM' terminal and the red test lead into the 'INPUT' terminal.
• Ensure a secure connection before making any measurements.

6. Operating Instructions

The KC602 features a 'SMART' mode for automatic recognition of measurement types, but also allows for manual function selection.

Figure 6.1: Overview of the multi-functions available on the KAIWEETS KC602.

6.1 Smart Mode (Auto Ranging)

When powered on, the meter defaults to 'SMART' mode. In this mode, the meter automatically identifies the input signal (AC/DC voltage, resistance, continuity) and selects the appropriate measurement range.

6.2 Manual Function Selection

Press the AUTO/FUNC button to cycle through different measurement modes. The selected mode will be indicated on the display.

• AC/DC Current Measurement (Clamp Jaw):
  1. Select the current measurement mode (A~ or A=).
  2. Open the clamp jaw and enclose a single conductor. Ensure the jaw is fully closed.
  3. Read the current value on the display. For DC current, use the ZERO button to zero the reading before measurement if needed.

• AC/DC Voltage Measurement:
  1. Connect the test leads to the 'COM' and 'INPUT' terminals.
  2. Select the voltage measurement mode (V~ or V=).
  3. Connect the test probes across the circuit or component to be measured.
  4. Read the voltage value on the display.

• Resistance Measurement:
  1. Connect the test leads.
  2. Select the resistance mode (Ω).
  3. Ensure the circuit is de-energized. Connect the probes across the component.
  4. Read the resistance value.
• Capacitance Measurement:
  1. Connect the test leads.
  2. Select the capacitance mode (F).
  3. Ensure the capacitor is discharged before connecting the probes.
  4. Read the capacitance value.
• Diode Test:
  1. Connect the test leads.
  2. Select the diode test mode (symbol).
  3. Connect the red probe to the anode and the black probe to the cathode of the diode.
  4. Read the forward voltage drop. Reverse the probes to check for open circuit.
• Continuity Test:

7. Maintenance

7.1 Cleaning

• Wipe the meter with a dry, soft cloth. Do not use abrasives or solvents.
• Keep the input terminals free from dirt and moisture.

7.2 Battery Replacement

When the low battery indicator appears on the display, replace the batteries as described in Section 5.1. Remove batteries if the meter is not used for an extended period.

8. Troubleshooting

If the meter does not operate correctly, check the following:

• No Display: Check battery installation and ensure batteries are not depleted.
• Incorrect Readings:
  • Ensure test leads are properly connected and not damaged.
  • Verify the correct function and range are selected for the measurement.
  • For current measurements, ensure only one conductor is within the clamp jaw.
  • For DC current, use the ZERO function to eliminate offset.
• Meter Does Not Respond: Try turning the meter off and on again. If the issue persists, replace the batteries.

9. User Tips

• Always double-check your connections and selected function before taking a measurement to prevent damage to the meter or the circuit.
• When measuring current with the clamp, ensure the conductor is centered within the jaw for the most accurate reading.
• Utilize the backlight feature in dimly lit environments for better visibility of the display.
• The 'SMART' mode is convenient for general checks, but for specific measurements, manually selecting the function can provide more control and confidence in the reading.
