Setup
- Connect to Power Source: Insert the male USB Type C connector of the KWS 1802C into a USB Type C power adapter, power bank, or any Type C power output port.
- Connect Device to be Tested: Plug your USB Type C device (e.g., smartphone, tablet, laptop) into the female USB Type C port on the KWS 1802C.
- Power On: The device will automatically power on and display real-time measurements once connected. No additional power supply is required.
The KWS 1802C is designed for plug-and-play operation, providing immediate feedback on voltage, current, and power.
Operating Instructions
Once connected, the KWS 1802C display will show various parameters. The device typically cycles through different display modes or allows manual cycling via a button.
Understanding the Display:
- Voltage (V): Indicates the real-time voltage being supplied to the connected device.
- Current (A): Shows the real-time current drawn by the connected device.
- Power (W): Displays the calculated power (Voltage x Current) being consumed.
- Timing (H): Tracks the duration of the charging or power delivery session, up to 99 hours.
- Capacity (mAh/Wh): Accumulates the total charge or energy transferred over time. This value can typically be reset.
- Temperature (°C): Shows the internal temperature of the device or ambient temperature.
Using the Control Button:
The small button on the side of the device (refer to Figure 3) serves multiple functions:
- Short Press: Cycles through different display screens or data sets (e.g., voltage/current, accumulated capacity, timing).
- Long Press: Typically resets accumulated data such as timing (H) and capacity (mAh/Wh). Hold the button until the values clear.
Note: Specific button functions may vary slightly. Refer to the on-screen prompts or experiment with short and long presses to understand all functionalities.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the device. Do not use liquid cleaners or solvents.
- Storage: Store the device in a cool, dry place when not in use.
- Handling: Handle the device with care to avoid physical damage to the connectors or display.
Troubleshooting
No Display / Device Not Powering On:
- Ensure the male USB Type C connector is fully inserted into a working power source.
- Verify that the power source itself is active and providing power.
- Check for any visible damage to the device or its connectors.
Incorrect Readings:
- Ensure both the power source and the connected device are functioning correctly.
- Confirm that the device is within its specified operating ranges (4-30V, 0-5.1A).
- Try connecting the meter to a different power source and device to isolate the issue.
Display Frozen or Unresponsive:
- Disconnect and reconnect the device to reset it.
- If the issue persists, contact customer support.
