Gauge (please read comment)

Iam not 100 percent sure, first the MEASUREMENT, short pulse or not or both?!!! (3times to press the Operation Button, to switch it) and later the DISPLAY after I pressed [for one time] the Operation Button, would be 100 percent but as explained in the Video, right now is not the strongest stuff here! would call it surveillance!
YET for sure over many days, hours its not good!!! (what we have right now)

Or exposure Leds to show the Battery status... anyway the question remains... always to see it or not (only after Operation Button)
