If You Encounter a Problem

If You Encounter a Problem

If you have difficulty when installing or using the analyzer, check the following list of commonly encountered problems and troubleshooting procedures. If the problem that you encounter is not in the following list, refer to additional troubleshooting sections in the 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 2-17to remove the fuse from the power module. You can use a 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 Fuse, T 5A 125V, UL listed/CSA certified to 248 standard (part number 2110-1059). For 230V operation, use Fuse, T 4A H 250V, built to IEC 127-2/5 standard (part number 2110-1036).

•Contact the nearest Agilent Technologies office for service, if necessary. A list of Agilent Technologies sales and service offices is provided in Table 2-1 on page 2-26.
