Kev ntsuas ntsuas ntawm Digital multimter pib ntau yam
Insert the test leads into the "COM" and "VΩ" holes, turn the knob to the desired range in "Ω", and connect the test leads to the metal parts at both ends of the resistor.
Daim ntawv ceeb toom:
1. If the measured resistance value exceeds the maximum value of the selected range, the over-range "1" will be displayed, and a higher range should be selected. For the resistance greater than 1MΩ or higher, it will take several seconds for the reading to stabilize. This is normal.
2. When not well connected, such as open circuit, the meter displays "1".
3. Thaum kuaj xyuas qhov impedance ntawm kab nyob rau hauv kev sim, nco ntsoov tshem tawm tag nrho cov khoom siv fais fab hauv kab hauv qab kev sim thiab tso tawm tag nrho cov capacitors. Yog tias muaj cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob khaws cia hauv kab hauv qab kev sim, nws yuav cuam tshuam qhov tseeb ntawm kab impedance xeem.
4. The 200MΩ gear of the multimeter has 10 characters in short circuit. When measuring a resistance, these 10 characters should be subtracted from the measurement reading. For example, when measuring a resistance, it is displayed as 101.0, and 10 characters should be subtracted from 101.0. The actual resistance value of the measured component is 100.0 or 100MΩ.
5. Koj tuaj yeem kov qhov kev tawm tsam nrog koj txhais tes thaum ntsuas, tab sis tsis txhob kov ob qhov kawg ntawm kev tawm tsam nrog koj txhais tes tib lub sijhawm - tib neeg lub cev yog tus neeg xyuas pib nrog lub zog loj tab sis txwv tsis pub.
