19.4.5 Levels - Design
The data on the LEVELS - DESIGN worksheet is entered by typing the appropriate numerical value into a cell
on the worksheet. An error message will be displayed if the value is invalid or incorrect.
To set polarity through the LEVELS - DESIGN worksheet, enter either + (positive) or – (negative) in the
polarity eld. The polarity of each output can be independently locked using the LOCK POLARITY? eld,
which is only available via this worksheet.
To lock polarity of an output, change the value in the associated LOCK POLARITY? eld to Y. The example
Module in Figure 19-16 has the polarity of all channels locked except for the input and lowest output.
