3.PRECAUTIONS BEFORE OPERATION
3-1.Unpacking the Oscilloscope
The product has been fully inspected and tested before shipping from the
factory. Upon receiving the instrument, please unpack and inspect it to
check if there is any damages caused during transportation. If any sign of
damage is found, notify the bearer and/or the dealer immediately.
3-2.Checking the Line Voltage
The oscilloscope can be applied any kind of line voltage shown in the
table below. Before connecting the power plug to an AC line outlet, make
sure the voltage selector of the rear panel is set to the correct position
corresponding to the line voltage. It might be damaged the instrument if
connected to the wrong AC line voltage.
WARNING. To avoid electrical shock the power cord
protective grounding conductor must be connected to ground.
When line voltages are changed, replace the required fuses shown as below:
Line voltage Range Fuse Line voltage Range Fuse
100V
120V 90-110V
108-132V
T 1A250V 230V 207-250V T 0.4A250V
WARNING. To avoid personal injury, disconnect the power
cord before removing the fuse holder.

3-3.Environment
The normal ambient temperature range of this instrument is from 0 ° to
40
°C (32° to 104°F). To operate the instrument over this specific
temperature range may cause damage to the circuits.
Do not use the instrument in a place where strong magnetic or electric
field exists as it may disturb the measurement.
3-4.Equipment Installation, and Operation
Ensure there is proper ventilation for the vents in the oscilloscope case. If
the equipment is used not according to the specification, the protection
provided by the equipment may be impaired.
3-5.CRT Intensity
To prevent permanent damage to the CRT phosphor, do not make the
CRT trace brighten excessively or leave the spot stay for an unreasonably
long time.
3-6.Withstanding Voltages of Input Terminals
The withstanding voltages of the instrument input terminals and probe
Input terminals are shown in the following table. Do not apply voltages
higher than these limits.
Input terminal Maximum input voltage
CH1, CH2, inputs 400V (DC + AC peak)
EXT TRIG input 400V (DC + AC peak)
Probe inputs 600V (DC + AC peak)
Z AXIS input 30V (DC + AC peak)
CAUTION. To avoid damaging the instrument, do not apply input
voltages of the frequency over 1 kHz to the instrument.
