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.
