4.4.1.3 BLOCK DIAGRAM DESCRIPTION
Figure 4-2 shows that the level input is converted to a string that is compatible with the power
supply, floating with 5 places to the right of the decimal (%.5f). Then, using the VISA write func-
tion, the string is sent to the power supply. The case statement in the middle of Figure 4-2
shows that all Kepco power supplies support this same functionality.

Figure 4-3 shows that when the error is true ( not equal to zero), the function is a null function,
passing the inputs (VISA session, Model, Channel and error) through the function without modi-
fication.
