Ignore any red dials.
Adjacent dials turn in opposite directions.
The number and position of dials may vary.
If the pointer is between two ﬁgures, always read the lowest of the 2 numbers (so if the pointer is between 5 and 6, the number you read is 5).
If the pointer is directly on a number, for example 7, look at the next dial to the right. If that dial on the right is between 9 and 0, you read 6 for the initial dial. If the dial on the right is between 0 and 1, you read 7 for the initial dial.
Always provide any zeroes to the left of the decimal point part of your reading
