Repair |
| Notes: |
The mux was returned from Campbell where they repaired it:
The unit had a high current drain and would not read input channels properly. Replaced three ICS 4052 analog mux/demux. Calibrated PRT. The multiplexor was probably damaged by a large voltage surge.
Maybe lightening, need to make sure things are properly grounded. |
