How can the direct current file's (DCA) quality be मूल्यांकन?
यदि there a a ज्ञात धारा स्रोत, input it direct in the current range. यदि नॉट, it d't mat. Just in in धारा रेंज. यदि it it is 1, switch to a लोअर रेंज तब तक प्रभावी मान दृश्य प्रकट होता है. , it to the the follow:
A. Pléz do not input too उच्च वोल्टेज, so as not to नुकसान the instrument due to too much current. Commonly used sources that can input are साधारण बैटरी, ऐसे as No. 5 और No. 7;
B. जब माप धारा the input वोल्टेज, क्योंकि प्रतिरोध (भार) आव आंतरिक प्रतिरोध of उपकरण i बहुत छोटे, if the input is TOO Long, the source WILL b क्षतिग्रस्त, SO TRY नॉट to EXED 5 सेकंड for a सिंगल इनपुट;
C. प्रत्येक उच्च और निम्न रेंज, और आसन्न श्रेणियाँ, सामान्यतः have a संबंध of 10 बार.
How to जज चाहे the कैपेसिटर फ़ाइल (CAP) is अच्छा या नॉट?
आम तौर पर, find a a कैपेसिटर विथ a ज्ञात मान और insert it direct for माप. द प्रदर्शित मान of a a reg range be in a {10-fold ratio; it is best to use a good metal capacitor for dection, जो has stable क्षमता और उच्च परिशुद्धता. यह is not reconed to use इलेक्ट्रोलाइटिक कैपेसिटर for इंस्पेक्शन, क्योंकि स्थिरता और सटीकता of uEcit a=Capacitor
How to judge (डिटेक्ट) the AC वोल्टेज रेंज (ACV) of the मल्टीमीटर is अच्छा?
Household detection sources include AC adapters, household sockets (two-phase 220V, it is best not to measure three-phase 380V, because this voltage is more dangerous, and it is harmful to the instrument (at least a multimeter above CAT III 600V) and the user. For safety reasons, it is recommended to measure a relatively small voltage first, such as an AC adapter, and then measure the voltage of a household socket. For specific safe operation methods, please refer to the product manual.
