2. Safety Information

This meter is designed to comply with IEC1010 safety standards. Please read this manual carefully before use.

General Safety Precautions:

• Do not input DC or AC voltage into the meter.
• Voltages below 36V are considered safe. When measuring capacitors, ensure they are fully discharged to avoid electric shock.
• When measuring components online, ensure the test leads are disconnected from the test points before changing functions.
• The "" symbol indicates that the operator must refer to the instructions in the manual. The "" symbol indicates low voltage.

Before Testing:

• Observe polarity when connecting polarized capacitors.
• Ensure any capacitor to be tested is fully discharged.
• Never connect the test jacks to voltage, as this may cause severe damage.
• Do not short-circuit the test leads, as this will cause excessive current consumption.

5. Setup

5.1 Battery Installation

The multimeter requires a 9V battery (not included). To install the battery:

1. Locate the battery compartment on the back of the multimeter.
2. Use a screwdriver to open the battery compartment cover.
3. Connect a 9V battery to the battery clip, observing correct polarity.
4. Place the battery into the compartment and replace the cover, securing it with the screw.

5.2 Initial Power On

After installing the battery, press and hold the POWER B/L button to turn on the multimeter. The LCD display will show a reading. A short press of the POWER B/L button will turn on/off the screen backlight.

6. Operating Instructions

6.1 General Measurement Procedure

1. Based on the expected maximum value of the capacitor or inductor, select the appropriate range using the rotary knob.
2. For 200pF, 2nF, and 20nF ranges, check the zero display before connecting the component. If necessary, rotate the zero adjustment knob on the front panel until the display reads zero. This zero adjustment is accurate to approximately ±15±5pF.
3. Connect the test leads to the component. You can use the provided test leads or the alligator clips for easier connection.
4. Plug the test leads into the Cx/Lx input jacks on the multimeter.
5. Press the TEST button.
6. Read the displayed value. The value will be shown directly in the unit selected by the range switch (pF, nF, uF, mH, H). If the display shows "1", it indicates an over-range measurement. If the displayed number has one or more leading zeros, move to a lower range to improve resolution.

6.2 Testing Inductors and Capacitors (Demonstration)

The following video demonstrates how to test inductors and capacitors using the multimeter, including connecting the test socket and alligator clips.

6.3 Important Considerations for Testing

• If a capacitor has no nominal value, start testing from the 200pF range and switch to higher ranges until the over-range display disappears and a reading is obtained.
• For shorted capacitors, all ranges will show an over-range reading. For capacitors with low leakage current, the measured capacitance value will be much higher than the actual value. For open-circuit capacitors, all ranges will show a zero reading.
• When testing very small capacitors, use short test leads to avoid introducing stray capacitance.
• If using optional test leads, remember that they may introduce a significant capacitance. First, measure the open-circuit capacitance of the test leads and subtract this correction value from subsequent measurements for accurate results.
• Some capacitors, especially electrolytic capacitors, have a wide range of capacitance values. If the measured value is significantly different from the nominal value, do not be alarmed unless it is a specially isolated capacitor. However, the measured value should rarely be much smaller than the rated value.
• If the measured value changes significantly when switching ranges, it may indicate the presence of leakage resistance. Leakage resistance can generally be detected, and its effect is reduced in lower ranges.

7. Maintenance

This series of meters are precision instruments. Users should not modify the circuit arbitrarily.

• Protect the meter from water, dust, and drops.
• Do not store or use the meter in high temperature, high humidity, flammable, explosive, or strong magnetic field environments.
• Clean the exterior of the meter with a damp cloth and a mild detergent. Do not use abrasives, alcohol, or strong solvents.
• If the meter will not be used for a long time, remove the battery to prevent battery leakage and corrosion.
• When the screen displays the "" symbol, replace the battery promptly.
• When replacing the fuse, use a fuse of the same specification and model.

8. Troubleshooting

If your meter is not working properly, the following methods can help you quickly resolve common issues. If the problem persists, please contact a service center or dealer.

9. User Tips

• Always ensure the component is fully discharged before testing, especially large capacitors, to prevent damage to the meter or the component.
• For precise measurements, use the zero adjustment feature for small capacitance values.
• Keep the test leads clean and in good condition to ensure reliable connections and accurate readings.
• When measuring in-circuit, be aware that other components in the circuit can affect the reading. For the most accurate results, test components out of circuit if possible.
