Here''s how I go about it: Follow these step-by-step instructions: Step 1: I always start by turning the multimeter''s knob to the capacitance mode.. Look for the capacitor …
How to Read a Capacitor: 13 Steps (with Pictures)
Check the voltage rating. If there is room on the body of the capacitor, the manufacturer usually lists voltage as a number followed by a V, VDC, VDCW, or WV (for "Working Voltage"). This is the maximum voltage the capacitor is designed to handle. 1 kV = 1,000 volts. See below if you suspect your capacitor uses a code for voltage (a single …
