멀티미터 사용 노브 의 전환 스위치 변경 측정 항목 및 측정 범위. 기계적 제로 노브 is 사용 to 유지 the 포인터 at 휴식 at 왼쪽 제로 위치. 더 "Ω" 제로 노브 is 사용 정렬 포인터 에 오른쪽 제로 위치 언제 측정 저항 to 보장 정확한 측정 값.
측정 범위 의 멀티미터 is as 팔로우:
-DC 전압: 5 등급 - 0-6V; 0-30V; 0-150V; 0-300V; 0-600V.
-AC voltage: 5 steps - 0-6V; 0-30V; 0-150V; 0-300V; 0-600V.
-DC current: 3 levels - 0-3mA; 0-30mA; 0-300mA.

Measurement of resistance: - first short-circuit the meter stick together, so that the pointer deflected to the right, and then adjust the "Ω" zero knob, so that the pointer is exactly pointing to 0. Then the two rods were contacted by the measured resistance (or the circuit) at both ends, the pointer in the ohm scale (the first line) on the readings, and then multiplied by the number of the gear label is the resistance value of the measurement. The resistance value of the measured resistance. For example, with R * 100 block resistance measurement, the pointer is pointing at 80, then the measured resistance value of 80 * 100=8 K. Due to the "Ω" scale on the left part of the reading is dense, difficult to see the right, so the measurement should be selected when the appropriate ohm gear. Make the pointer in the middle or right part of the scale, so that the reading is clearer and more accurate. Each time you change the gear, you should re-connect the two meter rods short and re-adjust the pointer to the zero position in order to measure accurately.
측정 의 DC 전압: - 첫째로, 추정 크기 의 측정 전압, 그때 다이얼 변환 스위치 에 적절한 V 범위, 연결 더 포지티브 미터 스틱 에 "+" 끝 의 the 측정 전압, 및 네거티브 미터 스틱 에 "-" 끝 의 측정된 전압. 다음 일치 범위 의 블록 디지털 및 표준 DC 기호 "DC-" 스케일 ( 초 라인) on the pointer pointed to the number, to read out the size of the measured voltage. If measured with V300 volts, you can directly read the indicated value of 0-300. Such as measuring with V30 volts, just remove a "0" on the scale of 300 this number, seen as 30, and then 200, 100 and other numbers in turn, seen as 20, 10 can be read directly out of the pointer to indicate the value. For example, with V6 volts measuring DC voltage, the pointer points to 15, the measured voltage is 1.5 volts.
측정 의 DC 전류: - 최초 추정 크기 의 현재 to be 측정, and then the 변환 switch to the 적절한 mA 범위, and then connect the 멀티미터 in 시리즈 in the 회로, as shown in the the figure. At the same time, observe the scale marked with the direct current symbol "DC", such as the current range selected in the 3mA file, then, should be the surface of the scale of the number of 300, remove the two "0", as 3, and in turn 200, 100 as 2, 1, so that the current value can be read. Can read out the measured current value. For example, using DC 3mA file to measure DC current, the pointer at 100, the current is 1mA입니다.
측정 의 AC 전압: - 더 방법 의 측정 AC 전압 is 유사 to that of 측정 DC 전압, the difference is that there is no positive and negative points because of AC power, so when measuring AC, the meter stick does not need to be divided into positive and negative. The reading method is the same as that of DC voltage measurement above, except that the numbers should look at 위치 의 포인터 위 더 배율 표시 포함 AC 기호 "AC".
