open.
If the SCB-68 does not work when you power on the DAQ device, check the switch
settings, then check the fuse on the SCB-68, shown in Figure 2, and the output fuse
(if any) on the DAQ device. Littelfuse part number 235.800 (
www.littelfuse.com) is a
suitable replacement fuse. Before replacing any fuses, check for short circuits from
power to ground.
