AM/FM Scaling

The magnitude of the AM/FM output signal at full-scale is selection-specific and may be adjusted to fit the requirements of the application (see AM Terminal Adjustment on pg. 55 and FM Terminal Adjustment on pg. 73. Also see AM/FM Scaling on pg. 142).

Table 8 shows the default full-scale output setting of the AM/FM terminal for each selection. The column on the right side of Table 8 shows the actual AM/FM output for a keypad display of 100% (default setting).
