Ir-riżoluzzjoni hija li tiġġudika l-kwalità tar-riżultati tal-kejl ta 'għassa. Li tkun taf ir-riżoluzzjoni ta 'meter iħallik tkun taf jekk tistax tara bidliet żgħar fis-sinjal li qed jitkejjel. Pereżempju, jekk id-DMM għandu riżoluzzjoni ta’ 1mV fuq medda ta’ 4V, tista’ tara bidla żgħira ta’ 1mV (1/1000 ta’ volt) meta tkejjel sinjal ta’ 1V
If you're measuring less than 1/4 inch (or 1mm) in length, you're definitely not going to use a ruler with the smallest units in inches (or centimeters). If the temperature is 98.6 degree F, it's useless to measure with a thermometer that only has integer marks. You need a thermometer with a resolution of 0.1 degree F.
In-numru ta 'ċifri u kliem huma użati biex jiddeskrivu r-riżoluzzjoni tat-tabella. Il-multimetri huma kategorizzati skond in-numru ta 'ċifri u kliem li jistgħu juru.
A 3-and-a-half-digit meter can display three full-digit digits from 0 to 9, and one half-digit (only 1 or no display). A 3½-digit digital meter can achieve a resolution of 1999 words. A 4½-digit digital meter can achieve a resolution of 19999 words.
The resolution of digital tables is better in words than in bits, and the resolution of 3½-digit tables has been increased to 3200 or 4000 words.
The 3200-word digital meter provides better resolution for some measurements. For example, a 1999 word meter, when measuring voltages greater than 200V, you can't display 0.1V. The 3200-character digital meter can still display 0.1V when measuring the voltage of 320V. When the measured voltage is higher than 320V and the resolution of 0.1V is to be achieved, an expensive 20,000-character digital meter should be used.
