Safety and Installation
About this Manual
This manual contains the safety and installation information that a new user will need to
set up the Tektronix DMM4040
or DMM4050 Digital Multimeter (hereafter referred to
as the Meter) prior to operation. You will also find compliance information,
environmental considerations, general and electrical specifications, a list
of available user
documentation, and a list
of standard and optional accessories for the Meter.
Introduction
Both Meters are 6-1/2 digit, dual-display multimeters designed for bench-top, field
service, and system applications. Their full complement
of measurement functions plus
their RS-232, IEEE 488, and Ethernet Remote Interfaces make these multimeters ideal
candidates for precision manual measurements and use in automated systems.
For
portability, these multimeters include a carrying handle that also serves as a bail for
bench top operation.
There are a few feature differences between these two multimeters, and some
specifications are tighter for thc DMM4050. Features that exist in only one multimeter
will be identified with the addition
of "4050 Only" by each feature that is found only in
that model. Separate specification tables are also used to clarify the differences between
these nvo models.
The following is a list
of some of the features and functions:
• Bright, large-digit, wide-viewing-angle display
• Dual display for displaying two properties
of an input signal (e.g., ac voltage in one
display and frequency
in the other).
• Remote operation via IEEE 488, RS-232, and Ethernet interface.
• Trigger in and measurement-complete
out
• Front panel USB port for optional memory
• 6-1/2 digit resolution
• Half-rack width
• True rms ac
• 2 and 4-wire resistance measurements
• Extended 10 Q and I
GQ ranges
• Frequency measurements to 1
MHz
• Capacitance measurements (4050 Only)

•

Safety and Installation Instructions
Unpacking and Inspecting the Meter
Every care is taken in the choice of packing material to ensure that your Meter will reach
you in perfect condition.
If the Meter has been subject to excessive handling in transit,
there may be visible external damage to the shipping carton. In the event of damage , keep
the shipping container and packing material 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 the carrier and Tektronix immediately.
Save the container and packing material in
case you have to return the Meter.
Storing and Shipping the Meter
To prepare the Meter for storage or shipping, use the original shipping container if
possible, as it provides shock isolation for normal handling operations. If the original
shipping container
is not available, use a box that is 17.5 x 15 .5 x 8.0 inches, with
cushioning material that fills the space between the Meter and the sides of the box.
To store the Meter, place the box under cover
in a location that complies with the storage
environment specifications described in the "General Specifications" section later
in this
manual.
Power Considerations
The Meter operates on varying 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 detennined at the time of ordering. If the selected line
voltage does
not match the power that the Meter will be plugged into, the Meter's line-
voltage setting must be changed and replacement
of the line fuse may be required.
Selecting the
Line Voltage
The
Meter operates on four different input line Voltages. The selected line-voltage setting
is visible through the window in the line-fuse holder on the Meter's rear panel.
I. Unplug the
power cord.
2. Insert a small screwdriver blade into the narrow recess to the left
of the fuse
holder and pry it to the right until the holder pops out. See Figure 2.
3. Remove the voltage-selector block from the fuse holder.
4. Rotate the selector block until the desired voltage rating faces outward.
5. Replace the selector block back into the fuse holder.
6. Install the fuse holder back into the Meter and reconnect the power cord.
Changing the line-voltage setting may require a different line-power fuse for proper
operation.

The Meter has a line-power fuse in series with the power supply. Table 1 indicates the
proper fuse for each
of the four line-voltage selections. The line-power fuse is accessed
through the
rear panel.
I. Unplug the power cord.
2. Insert a small screwdriver blade into the narrow recess to the left of the fuse
holder and pry it to the right until the holder
pops out. See Figure 2.
3. Remove the fuse and replace
it with a fuse of an appropriate rating for the
selected line-power voltage. See Table I.
4. Replace the selector block back into the fuse holder.
