2. Safety Information

Please read and understand all safety instructions before operating this device. Failure to follow these instructions may result in electric shock, fire, or personal injury.

• Always ensure the device is turned off before connecting or disconnecting test leads.
• Do not attempt to measure circuits with voltage exceeding the maximum specified input (MAX 36VDC for CX/LX terminals).
• Replace the battery when the low battery indicator appears to ensure accurate readings.
• Do not operate the meter if it appears damaged or if the case is open.
• Keep the device away from water and extreme temperatures.

3. Product Components

5. Operation

5.1 Powering On/Off

Rotate the function dial from the 'OFF' position to any measurement range to turn the meter on. Rotate it back to 'OFF' to power off the device.

5.2 Zero Adjustment

Before taking a measurement, especially for small values, it is recommended to zero the meter. With the test leads open (not connected to any component), press the 'ZERO' button (often integrated with the HOLD button or a separate small button near the dial) to clear any residual readings.

5.3 Measuring Capacitance (CX)

1. Turn the function dial to the desired capacitance range (e.g., 200pF, 2nF, 20nF, 200nF, 2uF, 20uF, 200uF, 2000uF). Start with a higher range if the capacitance value is unknown.
2. Ensure the capacitor to be measured is fully discharged before connecting the test leads.
3. Connect the test leads to the terminals of the capacitor.
4. Read the capacitance value displayed on the LCD. Adjust the range if necessary for better resolution.

5.4 Measuring Inductance (LX)

1. Turn the function dial to the desired inductance range (e.g., 2mH, 20mH, 200mH, 2H, 20H). Start with a higher range if the inductance value is unknown.
2. Connect the test leads to the terminals of the inductor.
3. Read the inductance value displayed on the LCD. Adjust the range if necessary for better resolution.

5.5 Data Hold Function

Press the 'HOLD' button to freeze the current reading on the display. Press it again to release the hold and resume live measurements.

5.6 Backlight Function

Press the backlight button (often marked with an asterisk or light bulb icon) to turn the LCD backlight on or off, improving visibility in low-light conditions.

6. Maintenance

6.1 Cleaning

Wipe the meter with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure no moisture enters the device.

6.2 Storage

When not in use for extended periods, remove the battery to prevent leakage. Store the meter in a cool, dry place, away from direct sunlight and extreme temperatures.

7. Troubleshooting

7.1 No Display or Faint Display

• Check if the battery is correctly installed and has sufficient charge. Replace the 9V battery if necessary.
• Ensure the function dial is not in the 'OFF' position.

7.2 Inaccurate Readings

• Perform a zero adjustment before measurement.
• Ensure test leads are properly connected and not damaged.
• Verify that the correct measurement range is selected for the component.
• For capacitance, ensure the component is fully discharged before testing.

7.3 Meter Does Not Respond

• Turn the meter off and then on again.
• Replace the battery.
