The first four digits of the water meter are black, the fifth digit is red, and there are only three red pointers.
The "x0.1" next to the red pointer means "the number pointed by the pointer x 0.1 ton"; the "x0.01" next to the red pointer means "the number pointed by the pointer x 0.01 ton". Therefore, the upper scale should be 0.3485 tons.
