Fuse and Power Supply Check

Fuse and Power Supply Check

If the attenuator/switch driver fails to respond when the power switch is turned on, the power line fuse should be checked. The 1 A, 250 V time delay, power line fuse (part number 2110-0782) is located inside the AC input module.

You will have to remove the top cover of the instrument to check the power supply fuses. Two 3A, 250 V fuses, one with black and white wires

(+ 24 Vdc line) attached to the fuse holder and the other with violet and gray wires (+ 5 Vdc line) attached to the fuse holder, are located on the deck, next to the power supply board.

For continued protection against fire hazard, replace the power line fuse with the same type and ratings only (1A/250V time delay).

Figure 6-2 Power Supply Test Points

Power Supply Check

The power supply (part number 0950-2252) may be checked by measuring the voltages between TP3 (ground) and the following test points:

TP1	24 V + 10% – 5%
TP2	5.1 V ± 2%
