To read a dial meter like this, you start with the rightmost dial and record the number that the pointer has just passed. If the pointer is between two numbers, record the lower number. Do the same for each of the remaining dials, moving from right to left.
In the image, the pointer on the rightmost dial is 5, so we record 5. The pointer on the next dial is just past the 6, so we record 6. The pointer on the third dial is just past the 0, so we record 0. The pointer on the leftmost dial is just past the 2, so we record 2.
