SAFETY
Before connecting the instrument to a power source, care-
fully read the following information, then verify that the
proper power cord is used and the proper line fuse is
installed for power source. The specified voltage is shown
on the rear panel. If the power cord is not applied for
specified voltage, there is always a certain amount of dan-
ger from electric shock.
Line voltage
This instrument operates using ac-power input voltages
that 100/120/220/230 V at frequencies from 50 Hz to
60Hz.
Power cord
The ground wire of the 3-wire ac power plug places the
chassis and housing of the oscilloscope at earth ground.
Do not attempt to defeat the ground wire connection or
float the oscilloscope ; to do so may pose a great safety
hazard. The appropriate power cord is supplied by an
option that is specified when the instrument is ordered.
The optional power cords are shown as follows in Fig.1

Line fuse
The fuse holder is located on the rear panel and contains
the line fuse. Verify that the proper fuse is installed by
replacing the line fuse.
Voltage conversion
This oscilloscope may be operated from either a 100V to
230V, 50/60 Hz power source. Use the following proce-
dure to change from 100 to 230 volt operation or vice
versa.
1. Remove the fuse holder.
2. Replace fuse F1 with a fuse of appropriate value, 1
amp for 100 VAC to 120 VAC operation. 630 m amp for
220 VAC to 230 VAC operation.
3. Reinsert it for appropriate voltage range.
4. When performing the reinsertion of fuse holder for the
voltage conversion, the appropriate power cord should
be used. (See Fig. 1.)
