2.6. Power Source-related warnings
Protection of Power Cord and Unplugging
Power-supply cords should be routed so that they are not likely to be waked on or pinched by items placed upon or
against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit
from the instrument. For added protection for this instrument during a lightening storm, when it is left unattended and
unused for long periods of time, unplug it from the power source. This will prevent damage to the instrument due to
lightening and power-line surges.
Overloading
Do not OVERLOAD power source and extension cords as this can result in a risk of fire or electric shock.
2.7. Place-related warnings
Object and Liquid Entry
Never push objects of any kind into this instrument through openings as they may touch dangerous voltage points or
short out parts that could result in a fire or electric shock. Never spill liquid of any kind on the instrument. Do not use
this instrument near water- for example, near a bath tub wash bowl, kitchen sink, or laundry tub, in a wet basement, or
near a swimming pool, and the like. Keep the instrument away from damp air, water and dust. Unexpected trouble
may be caused when the instrument is placed in a damp or dusty place.
FLAMMABLE AND EXPLOSIVE SUBSTANCE
Avoid using this instrument where there are gases, and where there are flammable and explosive substances in the
immediate vicinity.
Unstable Location
Do not place this instrument on an unstable cart, stand, tripod, bracket, or table. The instrument may fall, causing
serious injury to a person, and serous damage to the instrument. Do not place or use the instrument in a place subject
to ventilation.
2.8. Operation-related warnings
Power Switch
Before plugging the power cord in be sure to check that the power switch is set to off for protection of the instrument.
Ground Connection
When connecting a probe , connect the ground side of the probe to the ground of the signal source. At a floating
status, a potential might be produced with respect to other devices or ground, resulting in damaging the instrument,
probe, other measuring instruments, etc.
Excessive Input Voltage
In order to avoid electric shock or fire, the input voltages to the probes, BNC connectors are specified as follows. Do
not apply higher voltages. Before using probe, check the rated voltage with the naked eye. Remove the unused probe
not to contact with ambient high voltage parts. If you apply a higher voltage more than 400Vpk , remove the probe out
of BNC terminals to ensure against accidental danger
Maximum Input Voltage
- CH1, CH2 all 400 V
