Introduction

This chapter explains how to prepare the Meter for operation by selecting the proper line
voltage, connecting an appropriate line power cord, and turning on the Meter. Also
included is information on the proper storage and cleaning of the Meter.

Unpacking and Inspecting the Meter

Every care is taken in the choice of packing material to ensure that your equipment will
reach you in perfect condition. If the equipment has been subject to excessive handling in
transit, there may be visible external damage to the shipping carton. In the event of
damage, the shipping container and cushioning material should be kept for the carrier's
inspection.
Carefully unpack the Meter from its shipping container and inspect the contents for
damaged or missing items. If the Meter appears damaged or something is missing,
contact both the carrier and Tektronix immediately. Save the container and the packing
material in case you have to return the Meter.

Storing and Shipping the Meter

The Meter should be stored under cover. The shipping container provides the most
suitable receptacle for storage, as it provides the necessary shock isolation for normal
handling operations.
Place the Meter inside a sealed bag. Place the bag into the cushioning material inside the
shipping container, and store in a location that complies with the storage environment
specification described in Chapter 1.
If the Meter is shipped, use the original shipping container if possible. It provides shock
isolation for normal handling operations. If the original shipping container is not
available, a box that is 17.5 x 15.5 x 8.0 , with cushioning material that fills the space
between the Meter and the sides of the box, should provide similar shock isolation.

Power Considerations

The Meter operates on power distribution standards found throughout the world, and
must be set up to operate on the line voltage that will power it. The Meter is packed ready
for use with a line voltage determined at the time of ordering. If the selected line voltage
does not match the power the Meter will be plugged into, then the Meter's line voltage
setting must be changed and the line fuse possibly replaced.

Selecting the Line Voltage

The Meter will operate on any one of four different input line voltages. The set line
voltage is visible through the window in the line fuse holder, found on the Meter's rear
panel.
To change the line voltage:
1. Remove the power cord from the Meter.
2. Insert a small screwdriver blade in the narrow recess to the left of the fuse holder and
pry to the right until the holder pops out, as shown in Figure 2-1.
3. Remove the voltage selector block from the fuse holder.
4. Rotate the selector block until the preferred voltage rating faces outward.
