HRC Output Frequency Set:
This Technalogix frequency agile product can be set for HRC frequency output.
This feature is controlled by an internal dip switch assembly, DS-1. The switch is
located near the right front corner (with the panel facing you) between the test
point and the output converter module. DS-1 is clearly marked on the PCB.
Switch #3 placed in the OFF position switches the output frequency to HRC on
all channels. The switch is normally set to ON at the factory.
