2. 안전 정보

WARNING: Always exercise extreme caution when working with electrical circuits. Failure to do so may result in serious injury or death.

• Ensure the multimeter's test leads are fully inserted into the correct sockets for the measurement type.
• Verify the manual rotary switch is set to the correct position before making any measurements.
• This meter cannot test all AC Current and below 100mV AC Voltage. Refer to the user manual for specific limitations.
• The multimeter features double fuse protection against overloading.
• The silicone cover provides protection against drops and helps prevent electric shocks.
• A low battery indication will be displayed when battery power is low; replace batteries promptly to ensure accurate readings.
• Always disconnect power to the circuit before connecting or disconnecting test leads, especially when measuring current.

5. 설정

5.1 배터리 설치

The multimeter requires one 9V 6F22 battery (included). If the battery is not pre-installed or needs replacement, open the battery compartment on the back of the device, insert the new battery, and secure the cover.

5.2 테스트 리드 연결

Connect the red test lead to the VΩmA input jack and the black test lead to the COM input jack for most measurements. For high current measurements (up to 10A), connect the red test lead to the 10A input jack.

6. 사용 설명서

Before any measurement, ensure the test leads are correctly connected and the rotary switch is set to the desired function. The multimeter features a backlit LCD display for easy reading in low-light conditions, Data Hold to freeze readings, and Auto Shutoff to conserve battery life.

6.1 AC/DC Vol 측정tage

볼륨을 측정하려면tage, set the rotary switch to the appropriate AC V (~) or DC V (---) range. Connect the test leads in parallel to the circuit or component you wish to measure. The display will show the voltag전자 읽기.

6.2 DC 전류 측정

To measure DC current, set the rotary switch to the appropriate DC A (---) range. Connect the multimeter in series with the circuit. Ensure the circuit is de-energized before connecting the multimeter. This meter cannot test all AC Current.

6.3 저항 측정

To measure resistance, set the rotary switch to the Ω (Ohm) range. Connect the test leads across the component. Ensure the component is isolated from the circuit and de-energized before measuring resistance.

6.4 연속성 테스트

For continuity testing, set the rotary switch to the continuity symbol. Touch the test leads to the two points you want to check. If there is continuity (a complete circuit), the multimeter will emit an audible buzzer sound and display a low resistance reading.

6.5 다이오드 테스트

To test a diode, set the rotary switch to the diode symbol. Connect the red test lead to the anode and the black test lead to the cathode. The multimeter will display the forward voltage 드롭. 리드를 반대로 연결하십시오. 개방 회로 판독값이 나오면 다이오드가 정상임을 나타냅니다.

6.6 배터리 용량tage 테스트

The multimeter can accurately detect and display the status of 1.5V, 9V, and 12V batteries. Set the rotary switch to the appropriate battery test setting (1.5V BATT, 9V BATT, or 12V BATT). Connect the red test lead to the positive terminal and the black test lead to the negative terminal of the battery. The display will show the voltage value and indicate the battery status (Full, Normal, Bad).

6.7 Multimeter in Appliance Repair

The multimeter can be a valuable tool for diagnosing issues in household appliances. For example, it can be used to check voltages in a dryer or test a start switch in a washer.

7. 유지관리

• 멀티미터를 깨끗하고 건조하게 유지하십시오. 부드러운 천을 사용하십시오.amp 청소할 때는 천을 사용하십시오. 연마성 세제나 용제를 사용하지 마십시오.
• 멀티미터를 직사광선과 극한 온도 변화를 피해 서늘하고 건조한 곳에 보관하십시오.
• 정확한 측정값을 얻으려면 디스플레이에 배터리 부족 표시등이 나타나면 배터리를 교체하십시오.
• Inspect test leads for any damage before each use. Replace damaged leads immediately.

8. 문제 해결

• 화면 표시 안 됨/잘못된 측정값: Check if the test leads are fully inserted into the correct sockets. Ensure the manual rotary switch is in the correct position. Verify battery charge and replace if low.
• 연속성 경고음 없음: Ensure the rotary switch is set to the continuity test function. Check if the circuit is open.
• Meter Not Measuring AC Current or Low AC Voltage: This meter has limitations and cannot test all AC Current and below 100mV AC Voltage. Refer to specifications for detailed ranges.
