2-3. Fuse Check
A spare fuse should be included with the LPT 3000. The holder is located in the upper
part of the power switch on the back of the device. The spare is contained behind the
fuse currently in use. If there is no longer a spare fuse in this location, a replacement
should be acquired that matches the following properties. (250 VAC, 3.15 A type T 5 ×
20 mm).
2-4. Power Cable
In accordance with International Safety Standards, the LPT 3000’s power cable uses 3
lines including ”Ground.” When connected to a power outlet, the cable grounds the
cabinet of the unit.
2-5. Environmental Conditions
The LPT-3000 Spectrum Analyzer will operate normally between the temperatures of 0 ℃
and 40 ℃. However, for best performance, it is important to avoid exposing the unit to
conditions involving severe vibration, high moisture, direct sun rays, or areas where the
source voltage changes constantly.
To reduce the risk of fire, please use only the recommended fuses.
Using a fuse with a different power rating may cause serious damage to
the spectrum analyzer.
Please use a grounded power cable with three lines, or connect the
spectrum analyzer to a protective “Ground” line. Operating the unit
without following these requirements may put you at risk of an electric
shock. It is also important to check the source voltage, because if it
exceeds the recommended value, the spectrum analyzer may be
permanently damaged or catch fire.
