Preparation for Use
This section gives you important safety information and tells you
how to proceed with initial start-up of the TEKTRONIX 2205 Oscil­
loscope.
Before connecting the 2205 Oscilloscope to a power source,
read this entire section. Also refer to the Safety Summary at the
front of this manual for power source, grounding, and other
safety considerations pertaining to the use of the instrument. Be
sure that you have the training required to safely connect the
2205 to the signals you want to measure.
The 2205 operates from either a 115-V or a 230-V nominal ac
power line with any frequency from 48 Hz to 440 Hz. Before
connecting the power cord to a power source, verify that the
LINE VOLTAGE SELECTOR, located on the rear panel, is set cor­
rectly and that the proper line fuse is installed. Refer to Table
1 -1 , Figure 1 -1 , and the instrument rear panel.
To convert the 2205 for operation on the other line-voltage
range, first check that the power cord is not connected to any
power source. Then use a flat-bladed screwdriver to move the
LINE VOLTAGE SELECTOR to the required position and install the
appropriate fuse (listed on the rear panel and in Table 6 -1 ).
S A F E T Y
This instrument may be damaged if operated with
the LINE VOLTAGE SELECTOR (on the rear panel)
set for the wrong applied ac source voltage or if a
wrong line fuse is installed.
