Bagaimana memilih multimeter sesuai dengan resolusi yang berbeda?
Resolusi adalah untuk menilai kualitas hasil pengukuran sebuah jam tangan. Mengetahui resolusi meter memungkinkan Anda mengetahui apakah Anda dapat melihat perubahan kecil pada sinyal yang diukur. Bagaimana memilih multimeter menurut resolusi yang berbeda: Misalnya, jika DMM memiliki resolusi 1mV pada rentang 4V, Anda dapat melihat perubahan kecil 1mV (1/1000 volt) saat mengukur sinyal 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.
Jumlah digit dan kata digunakan untuk menggambarkan resolusi tabel. Multimeter dikategorikan berdasarkan jumlah digit dan kata yang dapat ditampilkan.
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.
