How to measure ceramic capacitor with pointer multimeter
The 2KV 223 ceramic capacitor is to be measured with a pointer multimeter. The capacitance is too small. The multimeter with capacitance capacity test can be tested. The resistance register of the general pointer type multimeter can only be used to judge the quality of the larger electrolytic capacitor, but it can not measure the capacity directly.
First, discharge the capacitor (short circuit, two feet). If the pointer has a capacitor, the knob is placed in the appropriate gear (of the capacitance, 223 of which means that the capacitance is 0.22 F) and the capacity is measured;If the pointer table has no capacitor stalls, the most high-end multimeter on the resistance profile (e.g. 10K file or 100K file, such a small capacity, put in the 1K file below is not change), measurement of capacitor discharge, a pointer angle swinging to the right (when a pen eyes to look at the dial, but can not see the pen, because the charging time is very short), then pointer back in situ (because the swing is to charge the capacitor because of full power and resistance value is infinite) said capacitor is good, if the pointer back to in situ, the capacitor leakage, have gone bad. But this method can not measure capacity, can only judge whether the capacitor is good or bad.
Do you want to measure the value or the voltage? Universal meter can measure, but not very accurate. You don't want to use a universal meter to measure the voltage, and the universal watch is not omnipotent.
