Introduction and Specifications
Introduction 1
Introduction
The DMM4040 and 4050 are 6-1/2 digit, dual-display multimeters designed for
bench-top, field service, and system applications. Their full complement of measurement
functions plus its RS-232, IEEE 488, and Ethernet Remote Interfaces makes 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 additional features in the DMM4050 that are not present in the
DMM4040. These features will be identified with the annotation 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 two 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 Ω and 1 GΩ ranges
• Frequency measurements to 1 MHz
• Capacitance measurements (4050 only)
• Temperature measurement (4050 only)
• 10 A current capability
• Decibels (dB and dBm) with variable reference impedance and audio power
measurement capability
• Input terminals on both front and rear panels of the meter
• Closed-case calibration (no internal calibration adjustments)
This technical reference manual focuses on performance verification and calibration of
the Tektronix DMM4040 and 4050 Digital Multimeters (hereafter referred to as the
Meter).

Measurement Uncertainty
The Meter's measurement uncertainties are expressed in the form ( % of reading + % of
range ). In addition to the reading error and range error, you may need to add additional
errors for certain operating conditions. If the Meter is operated outside the temperature
range specified, an additional temperature coefficient error must be applied. For dc
voltage, dc current, and resistance measurements, apply an additional reading-speed
error. For ac voltage and ac current measurements, apply an additional low frequency
error or crest factor error.
The "% of reading" error varies according to the input level on the selected range. This
error is expressed in percent of input measurement. The “% of range” error represents the
floor noise of the range and represents the lowest meaningful resolution for that range.
The following example shows the reading error applied to the Meter's 24-hour 10 Vdc
specification: 0.0013% of input + 0.0004% of range.
Assuming the Meter is set to the 10V range with an input voltage of 1 V, the
measurement uncertainty would be: +/- [(0.0013% x 1V) + (.0004% x 10V)].
Permissible High Value = 1 + 0.000053V = 1.000053 V
Permissible Low Value = 1 - 0.000053V = 0.999947 V

Introduction
This chapter provides handling, cleaning, fuse replacement, disassembly, and assembly
instructions for the Meter.
Warranty Repairs and Shipping Information
If your meter is still under warranty, see the warranty information at the front of this
manual for instructions on returning the unit. A Tektronix telephone number and the
website address can be found in the “Contacting Tektronix” section at the front of this
manual.
General Maintenance Information
The following sections describe how to maintain the Meter.
Required Equipment
Equipment required for calibration, troubleshooting, and repair of the Meter is listed in
Table 3-1.
Power Requirements
To avoid electric shock, connect the Meter’s power cord to a
power receptacle with earth ground.
The Meter operates on power distribution standards found throughout the world, and
must be set up to operate on the correct line voltage 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. See the DMM4040 and 4050
Safety and Installation Manual for information on switching the Meter’s line voltage.
If you have not already done so, plug the line cord into the connector on the rear of the
Meter.
Static Safe Handling
All integrated circuits, including surface mounted ICs, are susceptible to damage from
electrostatic discharge (ESD). Modern integrated circuit assemblies are more susceptible
to damage from ESD than ever before.
Integrated circuits today can be built with circuit lines less than one micron thick,
allowing more than a million transistors on a 1/4-inch square chip. These submicron
structures are sensitive to static voltages under 100 volts. This much voltage can be
generated on a dry day by simply moving your arm. A person can develop a charge of
2,000 volts by walking across a vinyl tile floor, and polyester clothing can easily generate
5,000 to 15,000 volts during movement against the wearer. These low voltage static
problems are often undetected, because a static charge must be in the 30,000 to 40,000
volt range before a person will feel a shock.
Warning
Most electronic components manufactured today can be degraded or destroyed by ESD.
While protection networks are used in CMOS devices, they can only reduce, not
eliminate, component susceptibility to ESD.
2-3
DMM4040/4050
Technical Reference Manual
ESD may not cause an immediate failure in a component; a delayed failure or
"wounding" effect is caused when the semiconductor’s insulation layers or junctions are
punctured. The static problem is thus complicated in that failure may occur anywhere
from two hours to six months after the initial damage.
Two failure modes are associated with ESD. First, a person who has acquired a static
charge can touch a component or assembly and cause a transient discharge to pass
through the device. The resulting current ruptures the junctions of a semiconductor. The
second failure mode does not require contact with another object. Simply exposing a
device to the electric field surrounding a charged object can destroy or degrade a
component. MOS devices can fail when exposed to static fields as low as 30 volts.
Observe the following rules for handling static-sensitive devices:
1. Handle all static-sensitive components in a static-safe work area.
Use grounded static-control table mats on all repair benches, and always wear a
grounded wrist strap. Handle boards by their nonconductive edges only. Store plastic,
vinyl, and Styrofoam objects outside the work area.
2. Store and transport all static-sensitive components and assemblies in static shielding
bags or containers.
Static-shielding bags and containers protect components and assemblies from direct static
discharge and external static fields. Store components in their original packages until they
are ready for use.
Cleaning
To avoid electric shock or damage to the Meter, never get water
inside the meter.
To avoid damaging the Meter’s housing, do not apply solvents
to the Meter.
If the Meter requires cleaning, wipe it down with a cloth lightly dampened with water or
a mild detergent. Do not use aromatic hydrocarbons, chlorinated solvents, or methanolbased fluids to wipe down the meter.
Fuse Replacement
The Meter employs fuses to protect both the line-power and current measurement inputs.
Line-Power Fuse
The Meter has a line-power fuse in series with the power supply. Table 2-1 indicates the
proper fuse for each of the four line voltage selections. This fuse is located on the rear
panel.
Warning
Caution
To replace this fuse:
1. Unplug the power cord from the Meter and remove any test leads.
2. Remove the fuse holder by inserting 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
2-4
General Maintenance
Fuse Replacement 2
Figure 2-1. The Meter is shipped with a replacement fuse of the same rating as the
fuse installed in the fuse block.
3. Remove the fuse and replace with one rated appropriately for the selected line-power
voltage. See Table 2-1 for fuse ratings with specific line voltage.

Performance Test and Calibration
Introduction 3
Introduction
This chapter of the Calibration Manual provides performance tests to verify the Meter is
operating within published specifications as well as a complete calibration procedure.
The performance test and, if necessary, the calibration procedure can be performed both
periodically and after service or repair.
The performance tests can be used as an acceptance test upon receipt of the Meter. Use
the 90-day specifications when performing an acceptance test after performing a
calibration.

Performance Test and Calibration
Test Considerations 3
Test Considerations
For optimum performance, all test procedures should comply with the following
recommendations:
• Assure the calibration ambient temperature (T
28 °C. Ideally the calibration should be performed at 23 °C ±2 °C.
• Assure ambient relative humidity is less than 80%.
• Allow a 60-minute warm-up period.
• Use shielded twisted-pair PTFE-insulated cables to reduce settling and noise
errors.
• Keep all input cables as short as possible.
• Ensure that the calibration standards and test procedures used do not introduce
additional errors.
Ideally, the standards used to verify and adjust the Meter should be four
times more accurate than each full-scale error specification of the Mete r.
• Use Tektronix’s low thermal 4-Wire short for all voltages and ohmic shorts. See
Table 3-1 for the Tektronix’ part number.
Performance Tests
The following performance tests are provided to ensure that the Meter is in proper
operating condition. If the Meter fails any of the performance tests, calibration
adjustment and/or repair is needed. The performance test works best if executed in the
sequence shown in Table 3-2.
cal) is stable and between 18 °C and
Note
Each of the measurements listed in the following tests assumes the Meter is being tested
after a one-hour warm-up in an environment with an ambient temperature of 18 to 28 ºC
and a relative humidity of less than 80%.
All instrument settings for verification use power up conditions except as
noted by the verification step.
Volts DC Verification
Connect the Meter to the test equipment as shown in Figure 3-1 and, depending on which
meter you are calibrating, apply the voltages listed in Table 3-2 or Table 3-3. Some
verification test steps are firmware dependant. To determine the firmware revision of the
UUT:
1. Press ,
2. Press the softkey labeled System.
3. Press the softkey labeled Version.
Note the OutG SW value.
Verification forms can be found in Appendix A which can be copied and used to record
each meter reading.

Technical Reference Manual
Adjustment (Calibration)
Meter adjustments, or calibration, should be performed at the desired interval, or
whenever a verification test indicates a Meter function is out of tolerance. The Meter
accuracy will stay within specifications only if the adjustment procedure is performed at
regular intervals. A one-year interval is adequate for most applications. The Meter’s
accuracy specifications are not valid beyond the one-year interval.
Meter adjustments are accessed only through the remote interface with a series of
adjustment steps. The remote program directs the test equipment to apply a series of
shorts, opens, voltages, currents, and capacitance (DMM4050 only) to the Meter. At each
step, the Meter internally makes the necessary adjustment to bring the Meter into
specification. No internal mechanical adjustments are necessary.
Using an automated, computer-controlled procedure, the calibration and verification
procedures can be performed on the Meter in under 60 minutes. A sample adjustment
program is listed on the “Sample Adjustment Program” section later in this manual.
The Meter’s adjustments are password protected to prevent accidental or unauthorized
adjustments. The security password must be entered through the front panel or remote
interface before adjustments can be made to the Meter.
Unlocking the Meter for Adjustments (Calibration)
To unlock the Meter for adjustments from the front panel:
1. Press .
2. Press .
3. Press .
Press the soft key labeled
to decrement the character or to increment the
character. The character can be set to 0 through 9, A through Z, period (.), and
dash (-).
To move to the next character, press
.
4. Press to enter the password and unlock the Meter for adjustments.
Find the CALIBRATION:SECURE:STATE command in the “Supported SCPI
Commands” section of the DMM4040 and DMM4050 Programmer Manual for
information on unlocking the Meter for calibration.
The Meter is shipped from the factory with the password set to .
Unlocking the Meter for Adjustments Over a Remote Interface

Once familiar with the calibration series of setups, the calibration time may be sped up by
using the command “CAL OFF”. This command allows the instrument to automatically
go to the next logical step in the series. The last column in Table 3-15 identifies which
steps in the series can be run automatically. For example, all of the Open steps can be run
by entering:
CAL:CAL ORES, 100000000
CAL? OFF
Another example is automatically running the ACV zeros from step 3 through step 12 in
Table 3-15 with:
CAL:CAL ZVAC, 100.0E-3
CAL? OFF
Using the CAL? command without an argument turns off the single step
feature.
AC linearity steps must be run with AC Gain steps t o complete the AC
calibration.

Notes
DMM4040/4050
Technical Reference Manual
Aborting a Calibration Process
Aborting a calibration process while the Meter is attempting to
write new calibration constants to memory may corrupt the
calibration constants memory.
To abort a running calibration process, stop the program or issue a device clear command
over the remote interface. No constants are saved until the Meter receives a record
command.
Sample Adjustment Program
The example below shows an IEEE 488 program that uses some of the commands to
adjust the 1V ACV portion of the Meter. Note that the ACV linearity adjustment must be
followed with a gain adjustment. Print is an output command to the Meter. Input Line
reads a response from the Meter.
