I assumed that it worked like the battery meter.... 4.10 v = 4 blinks , pause, 1 blink pause then rapid flash for 0
This measures mA not volts.... to for 3300 mAs I was expecting 3 blinks pause 3 blinks pause etc....
Mine just blinks continuously... I gave up counting after 40 +
Each blink is each digit of mA and groups of fast flashes means 0.
3300mA = 3 blinks, pause, 3 blinks, pause, fast flashes, pause, fast flashes
30mA = fast flashes, pause, fast flashes, pause, 3 blinks, pause, fast flashes
The reason you counted so many flashes is because you left the knob in one of the on positions. It will just keep reading the same power level out over and over again.
Once you do PU5, turn the knob to the position you want to know the power of.
