Identifying a Faulty Fuse
A faulty fuse usually has a smoked glass area or broken filament. If no break is visible, you can
remove the fuse and test it with an ohmmeter.
Suspect a faulty fuse if:
• The 2410 differential refractometer fails to power on.
• The display is blank.
• The fan does not turn on.
For more information on detecting the cause of a blown fuse, refer to Section 7.3, Hardware
Troubleshooting.
Caution: To avoid electrical shock, power off and unplug the 2410 refractometer before
checking the fuse. For continued protection against fire hazard, replace the fuse only with
another fuse of the same type and rating.
Procedure
To replace a fuse:
1. Power off the 2410 refractometer and disconnect the power cable from the rear panel.
2. Insert your fingers into the fuse holder slots on the rear panel of the detector, then pull
with minimum force to remove the holder from the rear panel (see Figure 6-1).
3. Remove and discard the old fuse.
