Rmstator Voltage Peak Reading Adapter Dva Adapter RM10001

A DVA adaptor is also known as a peak reading adaptor. Small engine ignition systems use permanent magnets to make electricity. This electricity travels down the wires very quickly and in "spikes" so to speak. What a DVA does is capture those "spikes" and allows a standard digital multimeter to read those voltages. Without a DVA adaptor, a multimeter will either record a low voltage, or no voltage at all. Power sport ignition systems work on "peak" voltages, which is why a DVA is known as a "peak reading" adaptor. Multimeters read average voltages, not peak, so that is what our adaptor allows you to do.
