Power-On the Oscilloscope
Power
Requirements
Line voltage, frequency, and power:
• ~ 100-120 Vac, 50/60/400 Hz
• ~ 100-240 Vac, 50/60 Hz
• 275 Watts MAX
Mains supply voltage fluctuations are not to exceed ±10% of the nominal supply
voltage.
Ventilation
Requirements
The air intake and exhaust areas must be free from obstructions. Unrestricted air
flow is required for proper cooling. Always ensure that the air intake and exhaust
areas are free from obstructions.
The fan draws air in from the left side and bottom of the oscilloscope and pushes it
out behind the oscilloscope.
When using the oscilloscope in a bench-top setting, provide at least 2" clearance
at the sides and 4" (100 mm) clearance above and behind the oscilloscope for
proper cooling.
To power-on the
oscilloscope
1 Connect the power cord to the rear of the oscilloscope, then to a suitable AC
voltage source. Route the power cord so the oscilloscope's feet and legs do not
pinch the cord.
Install the instrument so that the detachable power cord is readily identifiable
and is easily reached by the operator. The detachable power cord is the
instrument disconnecting device. It disconnects the mains circuits from the
mains supply before other parts of the instrument. The front panel switch is only
a standby switch and is not a LINE switch. Alternatively, an externally installed
switch or circuit breaker (which is readily identifiable and is easily reached by
the operator) may be used as a disconnecting device.
2 The oscilloscope automatically adjusts for input line voltages in the range 100
to 240 VAC. The line cord provided is matched to the country of origin.
3 Press the power switch.
The power switch is located on the lower left corner of the front panel. The
oscilloscope will perform a self-test and will be operational in a minute or so.
To power cycle the
oscilloscope
From the menu, choose File > Power Cycle. This is the same as pressing the front
panel power button to power down the oscilloscope and then pressing the power
button again to start the oscilloscope.
WARNING
Always use a grounded power cord. Do not defeat the power cord ground.
