Example:

the high level voltage of a bus must be between +3.0 V

(MIN) and +15.0 V (MAX). Depending on the

measurement result the displayed indicator will be:

If the result is between 4.2 and 13.8V. (10% of

12 V = 1.2 V)

If the result is between 3 V and 4.2 V, or between

13.8 V and 15 V.

If the result is < 3 V or >15 V.
