Service Guide.

Power-Up Problems

If the analyzer display does not light:
• Check that the power cord is fully seated in both the main power receptacle and the
analyzer power module.
• Check that the AC line voltage selector switch is in the appropriate position
(230 V/115 V) for your available power supply.
• Check that the analyzer AC line fuse is not open.
WARNING For continued protection against fire hazard, replace the fuse with
the same type and rating.
Refer to Figure 2-17
continuity light or an ohmmeter to check the fuse. An ohmmeter should read very close
to zero ohms if the fuse is good. For 115V operation, use a 5A 125V TD fuse (HP part
number 2110-1059). For 230V operation, use a T 4A 250V fuse (HP part number
2110-0734).
