No Power to the Analyzer
If there are no characters on the front panel LED display and the fan does not
work while the analyzer is plugged in, the problem is most likely a blown fuse.
First check the power to the analyzer. Make sure the power cord is firmly
seated at both ends. Make certain that there is power to the outlet at the wall
or surge protector.
There are two fuses in the analyzer; a main power fuse and a power supply
fuse.
To check the main fuse:
1. Unplug the power cord from the left-hand side of the analyzer.
2. Use a small screw driver to pry open the AC inlet adapter located on
the left-hand side of the analyzer (see Figure 10-4).
3. Remove the fuse from the holder and replace, if necessary:
Analyzer Voltage Replacement Fuse Type
100V, 120V F 3.0A, 250 VAC, fast acting fuse (size 3AG)
230V* T 1.25A, 250 VAC, Time-Lag fuse (size 5x20mm)
* 230V unit has a second fuse in place of the spare fuse; both fuses must be the same type and rating.
