It is interesting to see how different hour glass type patterns are used to display the decimals on a modern kilowatt hour meter instead of the normal numbers.

This meter is an Enermet 3 phase 100 Ampère kWh meter.

The red impulsing led speed was not correctly picked up by the camera as it was pulsing faster than the 24 FPS of the video.

decimal 0 at 0:56 and 2:35
decimal 1 at 2:58
decimal 2 at 1:03 and 3:39
decimal 3 at 1:12 and 3:44
decimal 4 at 1:19
decimal 5 at 1:23
decimal 6 at 1:32
decimal 7 at 1:55
decimal 8 at 2:00
decimal 9 at 0:47 and 2:04
