In the event that a channel on a module quits responding with proper values,
it may be an indication that this protective fuse has blown. The fuse can be
removed from the circuit and checked for continuity with an ohm-meter
and/or replaced with a Littelfuse P/N: 273.050 fuse available from Omega
Engineering Incorporated or many electronic distributors.
