5. 설정

5.1 배터리 설치

The ANENG SZ11 Multimeter requires two AA batteries for operation. To install or replace batteries:

1. Unscrew the back cover of the multimeter.
2. AA 배터리 2개를 올바른 극성(+/-)에 맞춰 넣으세요.
3. 뒷면 덮개를 다시 씌우고 나사로 고정하십시오.

5.2 테스트 리드 연결

Proper connection of test leads is crucial for accurate and safe measurements. The multimeter features an intelligent LED Jack Indicator to guide you:

1. Turn the rotary dial to the desired measurement function.
2. The corresponding input jacks will light up (green light reminder).
3. 검정색 테스트 리드를 'COM'(공통) 잭에 삽입하십시오.
4. Insert the red test lead into the illuminated input jack appropriate for your measurement (e.g., 'INPUT' for voltage/resistance, 'mA' or '20A' for current).

6. 사용 설명서

To operate the ANENG SZ11 Multimeter, select the desired function using the rotary dial and connect the test leads as indicated by the LED jack lights.

6.1 DC 볼륨tage 측정

Turn the dial to the 'V=' position. Connect the red test lead to the positive terminal and the black test lead to the negative terminal of the DC source. The display will show the DC voltage. Measurable up to 1000V.

6.2 AC 볼륨tage 측정

Turn the dial to the 'V~' position. Connect the test leads across the AC source. The display will show the AC voltage. Press the 'FUNC' button to switch between AC and DC if needed. Measurable up to 750V. The MAX/MIN button can be used to display the maximum or minimum detected voltage.

6.3 Millivolt DC/AC Voltage 측정

소량의 경우tage measurements, turn the dial to the 'mV' position. Press the 'FUNC' button to toggle between DC and AC millivolts. This mode offers high precision for sensitive measurements.

6.4 Frequency (Hz) and Duty Cycle Measurement

Turn the dial to the 'Hz%' position. Connect the test leads to the circuit where frequency or duty cycle needs to be measured. Press 'FUNC' to switch between Frequency (Hz) and Duty Cycle (%).

6.5 연속성 테스트

Turn the dial to the 'Ω' position and press 'FUNC' until the continuity symbol (a speaker icon) appears. Touch the test leads to the two points of the circuit. A beep indicates continuity (a complete circuit). This function is useful for locating broken lines or checking fuses.

6.6 저항 측정

Turn the dial to the 'Ω' position. Connect the test leads across the component to measure its resistance. The multimeter will auto-range to provide the reading. Ensure the circuit is de-energized before measuring resistance.

6.7 다이오드 테스트

Turn the dial to the 'Ω' position and press 'FUNC' until the diode symbol appears. Connect the red lead to the anode and the black lead to the cathode of the diode. The display will show the forward voltage drop. Reversing the leads should show an open circuit (OL) for a healthy diode. This can also light up small lamp 염주.

6.8 커패시턴스 측정

Turn the dial to the 'F' position. WARNING: Always discharge capacitors before testing to prevent damage to the multimeter. Connect the test leads across the capacitor. The display will show the capacitance value.

6.9 온도 측정

Turn the dial to the '°C/°F' position. Connect the temperature probe to the input jacks. Place the probe on the object whose temperature you wish to measure. Press 'FUNC' to switch between Celsius and Fahrenheit.

6.10 Current Measurement (µA, mA, A)

WARNING: Current measurements require connecting the multimeter in series with the circuit. Incorrect connection can damage the multimeter or the circuit.

• 마이크로ampere (µA) / Milliampere (mA) DC/AC Current: Turn the dial to the 'µA' or 'mA' position. Press 'FUNC' to select AC or DC. Connect the multimeter in series with the circuit. The maximum measurable current is 600mA.
• Ampere (A) DC/AC Current: Turn the dial to the '20A' position. Press 'FUNC' to select AC or DC. Connect the multimeter in series with the circuit. The maximum measurable current is 20A.

6.11 NCV(비접촉식 볼tage) 감지

Turn the dial to the 'NCV' position. Bring the top of the multimeter close to an AC voltage source (e.g., a live wire). The display will show dashes, and the device will beep, indicating the presence of AC voltage. The closer the multimeter is to the voltage, the more urgent the beeping and screen flickering will be. This function can also be used to locate breakpoints in a line.

6.12 활선 감지

Turn the dial to the 'LIVE' position. Insert the red test lead into the 'INPUT' jack. Touch the red test lead to a wire. If it's a live wire, the screen will show 'LVE' and beep. If it's a neutral line, there will be no response.

6.13 손전등 및 백라이트

To activate the flashlight, press the flashlight button. To turn on the backlight for the display, long-press the backlight button. These features are useful for working in dark environments.

7. 유지관리

멀티미터를 닦으세요asin광고가 있는 gamp cloth. Do not use abrasive cleaners or solvents. Ensure the device is off and disconnected from any power source before cleaning.

7.2 퓨즈 교체

The ANENG SZ11 Multimeter has built-in fuses for protection. If the multimeter stops functioning correctly, especially during current measurements, the fuses may need replacement. The µA/mA fuse is F600mA/250V, and the 20A fuse is F20A/250V. To replace a fuse:

1. 멀티미터가 꺼져 있는지 확인하고 모든 테스트 리드를 분리하세요.
2. Unscrew the back case of the multimeter.
3. Carefully remove the old fuse using tweezers.
4. Insert a new fuse of the correct type and rating.
5. Reassemble the back case and secure it with screws.

8. 문제 해결

ANENG SZ11 멀티미터 사용 중 문제가 발생하면 다음의 일반적인 문제 해결 단계를 고려해 보세요.

• 화면 안 켜짐/배터리 부족: 배터리 설치 상태를 확인하고 배터리 잔량이 부족하면 교체하십시오.
• 잘못된 판독: Ensure the correct function and range are selected. Verify test lead connections. Clean test lead tips if corroded.
• 'OL' 표시: This typically indicates an overload (measurement exceeds the selected range) or an open circuit (no continuity). Adjust the range or check the circuit.
• 전류 측정 없음: Check if the appropriate fuse (µA/mA or 20A) has blown and replace if necessary. Ensure the multimeter is connected in series.
• 저항 측정값이 부정확함: While the multimeter offers good accuracy, some budget multimeters may show slight variations on certain resistance ranges. For critical measurements, consider professional-grade equipment.
