Description
DVA stands for Direct Voltage Adapter, which is used to measure peak AC voltage
This type of measurement of AC voltage takes the absolute peak or highest value of the fluctuating AC voltage signal
Peak readings will be substantially higher than standard or RMS AC values and are typically used when testing marine CD (capacitor discharge) ignition systems due to their high variance in frequency as RPM increases and decreases
In order for a digital meter to read peak voltage, one will need a DVA adapte
Using a DVA adapter, a digital meter must be set to its DC voltage scale
Peak AC voltage is the measurement, but the DVA adapter has a built-in bridge rectifier, which converts AC to DC
The DC voltage setting on a digital meter is required to accurately read DVA.
