Tektronix 466 User Manual

The instrument has a three-wire power cord with a
three-terminal polarized plug
for connection to the power
source and safety-earth. The
ground (earth) terminal of
the plug is directly connected to the instrument frame. For
electric-shock protection, insert this plug
only in a mating
outlet with a safety-earth contact.
OPERATING VOLTAGE
This instrument may be damaged if operated with
the line voltage
selector switch or the regulating
range
selector set for the wrong applied line voltage
or if the wrong line fuse is used.
Line Voltage Selection
This instrument operates from either a 115-volt or a
230-volt nominal line voltage source, 48 to 440 hertz. To
convert from one nominal line voltage range to the other,
move the Line Voltage Selector
switch (located on side
panel)
to indicate the correct nominal voltage. A 115-to-
230 volt adapter may be required
for the line-cord plug. Be
sure to use the
correct line fuse for the line voltage
selected (see Table 1).
Regulating Range Selection
The Regulating Range Selector assembly (located on
the rear panel) is set
for one of the line voltage ranges
shown in Table 1. It also contains the line fuse for overload
protection.
To change the regulating range:
1. Disconnect the instrument from the power source.
2. Loosen the two captive screws that hold the cover
on
the selector assembly; then pull to remove the cover.
3. Pull out the range selector switch bar (see Fig. 1 ).
Select a range from Table 1 which is centered about the
average line voltage. Slide the bar
to the desired position
and plug it in. Push the cover on and tighten the screws.
