**Example 1: Error When Displaying 85.000 km/h**

Calculation: 85.000 km/h × (0.006%) = ±0.0051 km/h

In this case, three digits are displayed below the decimal point, so the fourth digit below the decimal point in ±0.0051 km/h is rounded off to yield an accuracy of ±0.005 km/h. There is also an error of ±1 added to the rightmost digit (±0.001 km/h) for a total error of ±0.005 km/h ±0.001 km/h = ±0.006 km/h. Consequently, the display may vary between 84.994 and 85.006 km/h.

**Example 2: Error When Displaying 85.00 km/h**

Calculation: 85.000 km/h × (±0.006%) = ±0.0051 km/h

In this case, two digits are displayed below the decimal point, so the third digit below the decimal point in ±0.0051 km/h is rounded off to yield an accuracy of ±0.01 km/h. There is also an error of ±1 added to the rightmost digit (±0.01 km/h) for a total error of ±0.01 km/h ±0.01 km/h = ±0.02 km/h. Consequently, the display may vary between 84.98 and 85.02 km/h.

**Example 3: Error When Displaying 85.0 km/h**

Calculation: 85.000 km/h × (±0.006%) = ±0.0051 km/h

In this case, one digit is displayed below the decimal point, so the second digit below the decimal point in ±0.0051 km/h is rounded off to yield an accuracy of ±0.0 km/h. There is also an error of ±1 added to the rightmost digit (±0.1 km/h) for a total error of ±0.0 km/h ±0.1 km/h = ±0.1 km/h. Consequently, the display may vary between 84.9 and 85.1 km/h.
