Input power overload protection is provided by a 1.5 A slo-blo surface mount fuse installed in a fuse holder on the interface board. (To
access this board see
Accessing the Interface Board Connection Terminals
●
AC-powered instruments: Locate the fuse at the center of the interface board on top.
●
DC-powered instruments: Locate the fuse at the center of the interface board on the back (solder side). With power OFF remove two
securing 6-
32 x ½″ Phillips pan head screws and star washers from
the DC-powered interface board. Pull board straight up from mating
sockets to access the fuse at the back.
To check for a blown fuse:
1. Turn instrument power OFF.
2. Access the interface board (see text above).
3. Using an ohmmeter touch metal cap at each end of fuse with the test leads. Any reading other than a short (i.e., open circuit)
indicates a blown fuse. Replace with Littelfuse 454 Series fuse, part no. 045401.5.
