Maintenance
The Analyzer needs little maintenance or special care.
However, treat it as a calibrated measuring instrument.
Avoid dropping or other mechanical abuse that could
cause a shift in the calibrated settings.
 Warning
To prevent possible electrical shock, fire, or
personal injury:
• Remove the mains power cord. Stop for
two minutes to let the power assemblies
discharge before you open the fuse door.
• Replace a blown fuse with exact
replacement only for continued protection
against arc flash.
• Do not operate the Product with covers
removed or the case open. Hazardous
voltage exposure is possible.
• Disconnect the mains power cord before
you remove the Product covers.
• Remove the input signals before you clean
the Product.
• Use only specified replacement parts.
• Use only specified replacement fuses.
• Have an approved technician repair the
Product.
Testing and Replacing the Fuses
For electrical protection of the equipment outlet, the
Analyzer uses one fuse in the live (L1) line and one fuse in
the neutral (L2) line.
To test the fuses, do the following while referring to
Figure 14:
1. Remove the holster.
2. Remove the fuse door from the Analyzer by removing
the screw holding the fuse door with a #2 Phillips head
screwdriver and lifting the fuse door from the Analyzer.
3. Remove the fuses from the Analyzer.
4. Using a multimeter, measure the continuity of each
fuse.
If one or both fuses do not show continuity, replace the
fuse(s) with fuses that have the same current and
voltage rating. Appropriate fuse ratings are posted on
the case bottom label of the Analyzer. Table 6 lists
available fuses with Fluke Biomedical part numbers.
5. Reinstall the fuse door and secure it with the screw.
