PREPARATION FOR USE
SAFETY
Before connecting the instrument to a power source, carefully read the following infor-
mation, then verify that the proper power cord is used and the proper line fuse is installed
for power source. The specified voltage is shown at the left side of the power cord on
the rear panel. If the power cord is not applied for specified voltage, there is always a
certain amount of danger from electric shock.
Line voltage
This instrument operates using AC-power input voltages that 100/120/220/240 V at fre-
quencies from 50 Hz to 60 Hz.
Power cord
The ground wire of the 3-wire AC power plug places the chassis and housing of the oscil-
loscope 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.
EQUIPMENT PROTECTION
1. Never allow a small spot of high brilliance to remain stationary on the screen for more
than a few seconds. The screen may become permanently burned. A spot will occur
only when the scope is set up for X-Y operation and no signal is applied. Either reduce
the intensity so the spot is barely visible, switch back to normal sweep operation when
no signal is applied, or set up the scope for spot blanking.
2. Never cover the ventilating holes on the top of the oscilloscope, as this will increase
the operating temperature inside the case.
3. Never apply more than the maximum rating to the oscilloscope inputs.
^ CH1, CH2 INPUT jacks:
EXT TRIG INPUT jack:
Never apply external voltage to the oscilloscope output terminals.
4. Always connect a cable from the earth ground (GND) terminal of the oscilloscope to
the chassis of the equipment under test. Without this caution, the entire current for
the equipment under test may be drawn through the probe clip leads under certain cir-
cumstances. Such conditions could also pose a safety hazard, which the ground cable
will prevent.
5. Always use the probe ground clips for best results. Do not use an external ground wire
in lieu of the probe ground clips, as undesired signals may be introduced.
