जब a clip ammeter, be माइंडफुल of the निम्नलिखित चीज़ें
(1) Before using the digital multimeter, read the instruction manual carefully to familiarize yourself with the function of the power switch and the function of the limit switch, input jack, socket, and various function keys, knobs, and accessories. In addition, you should also understand the limit parameters of the multimeter, the characteristics of overload display, polarity display, low voltage display and other symbol display and alarm, and grasp the changing law of the decimal point position. Before measurement, carefully check whether the test lead is cracked, whether the insulation layer of the lead wire is damaged, and whether the position of the test lead is inserted correctly to ensure the safety of the operator.
(2) Before each measurement, check again whether the measurement item and the limit switch are in the correct position, and whether the input jack (or special jack) is selected correctly.
(3) द मीटर विल जंप जब जस्ट मापक, और you प्रतीक्षा प्रवेश दर्शित प्रदर्शित मान सेवनी स्थिर पूर्व पठन.
(4) AlThough the डिजिटल मल्टीमीटर has a Relatively Complete protection Circuit inside, IT is स्टिल आवश्यक to Avoid Operational errors, ASS USING a current block to माप वोल्टेज, USING an इलेक्ट्रिक ब्लॉक to माप वोल्टेज OR current, and USING a Capacitor block to माप आवेशित संधारित कैपेसिटोर, ETC., SO AS TO DAMAGE THE मीटर.
(5) If only the highest digit displays the number "1" and the other digits are blanked, it proves that the meter has been overloaded, and a higher limit should be selected.
(6) It is forbidden to toggle the limit switch जब a वोल्टेज ऊपर 10OV or a current ऊपर 0.5A, so as not to generate an arc and burn the contacts of the transfer स्विच.
(7) संख्या चिह्नित द खतरा चिह्न अगला to the input jack the input वोल्टेज या धारा jack. एक अधिक, it मई क्षति उपकरण और सम खतरे में सुरक्षा प्रचालक.
(8) camp मल्टीमीटर is नॉट अनुमत to माप द धारा of उच्च-वोल्टेज लाइन, और वोल्टेज of मापे गए लाइन निर्दिष्ट by the camp meter (सामान्यतः no more 500 volts), in order to inulation in to inulation 7777777
(9) माप अनुमान अनुमान आकार आमान मापित धारा, चयन दह उपयुक्त सीमा, और do not उपयोग लघु रेंज गियर to माप बड़ी धाराएँ.
(10) पे अटेंशन टू टर्न द रेंज स्विच टू द तदनुरूपी एसी करंट गियर पहले माप, और you उपयोग दह वोल्टेज गियर और प्रतिरोध गियर टू माप दह धारा.
Recall! Never use प्रतिरोध गियर और करंट गियर to माप वोल्टेज, if you are not सावधान, the मीटर विल be जला हुआ.
(11) Only one wire can be clamped for each measurement. When measuring, the wire to be tested should be placed in the center of the jaws to improve the accuracy of the measurement. It is best to level the body of the watch with your hands, and try not to let the wire lean against the jaws and the body of the watch.
(12) आफ्टर द मेजरमेंट, the range switch must be मुंड the अधिकतम वोल्टेज रेंज पोजीशन, और तब the power switch be for of of. To sure safe use next time.
