Keysight’s NEW Truevolt Digital Multimeters
(DMMs) offer a full range of measurement
capabilities and price points with higher levels of
accuracy, speed, and resolution.
Measure low-power devices
The ability to measure very low current, 1 µA range with pico
second resolution, allows you to make measurements on very low
power devices.
Maintain calibrated measurements
Auto calibration allows you to compensate for temperature drift
so you can maintain measurement accuracy throughout your
workday.
Get more insight quickly
Truevolt DMM's graphical capabilities such as trend and histo-
gram charts offer more insights quickly. Both models also provide
a data logging mode for easier trend analysis and a digitizing
mode for capturing transients.
The bright, 4.3” high-resolution monitor is a prominent feature of
Keysight’s Truevolt DMM family.

Measure with Unquestioned Truevolt
Condence
Worry about the quality of your design, not the
quality of your measuments
In a rack or on a bench real-world signals are never at. They
have some level of AC signal riding on top from power line noise,
other environmental noise, or injected current from the meter
itself. How well your meter deals with these extraneous factors
and eliminates them from the true measurement makes a big dif-
ference to your accuracy. Behind the scenes, Keysight’s Truevolt
technology accounts for measurement errors created by these
real-world factors so you can be condent in your measurements
and it is only available on Keysight DMMs.
Truevolt technology starts with an analog-to-digital converter
that enables a patented metrology-grade architecture. Using this
architecture, Keysight delivers a good balance of measurement
resolution, linearity, accuracy, and speed at a value price, all de-
rived and guaranteed per ISO/IEC 17025 industry standards.

05 | Keysight | Digital Multimeters: 34460/61/65/70A - Data Sheet
What Truevolt technology means to you:
You can measure your real-world signals,
not instrument error
Noise and injected current: Keysight Truevolt DMMs contribute
less than 30% of the injected current than alternatives. Compared
to some lower cost alternatives, Truevolt DMMs offer almost
100% less noise.
You can measure your real-world signals with
condence
All Truevolt DMM specications are tested
and guaranteed for compliance with ISO/
IEC 17025 standards so you can prove the
effectiveness of your lab or production
line’s quality management system. Many
lower-cost DMMs in this class do not
carry a guarantee of their measurement
specications.
You can take advantage of expanded
measurement functionality
Compared to the 34401A DMM, Truevolt DMMs offer expanded
current ranges from 100 µA to 10 A. We have also added
a temperature measurement function (RTD/PT100, 5 kΩ
thermistor). Additionally, diode measurement capability has been
expanded to allow a larger full-scale voltage to be measured (5 V)
to enable the measurement of more diode types such as LEDs.
Peak value
RMS value
AC measurement
accuracy is degraded
when signals have
energy contained in
higher frequencies
than a typical sine
wave.
Crest factor: the ratio of the
peak value to the RMS value
of a waveform
Digital AC rms measurements: For meters in this class, only
Keysight uses digital direct sampling techniques to make AC rms
measurements. This results in a true rms calculation technique
that avoids the slower response of analog RMS converters used
in all other vendor’s 6½ digit DMMs. This allows for crest factors
up to 10 without additional error terms. This is a unique, patented
technique – only used by Keysight.

Input bias current: Ideally, no current ows into the measurement
terminals of your DMM. In real measurement situations, there are
always input currents creating additional measurement errors.
Truevolt DMMs take care of input bias current. Some alternative
DMMs offer 20% to innitely poorer performance (some are too
noisy to measure).

YES
Measurements Will I have the same performance so it
doesn’t affect the results on my line?
YES
Cost Will it cost the same to buy, use,
maintain, and repair?
YES
(and potentially less since the
DMMs now include a 3-year
standard warranty)
Reliability My 34401A never breaks. Are the
Truevolt DMMs going to be as good?
YES
That’s why we can offer
a 3-year standard warranty
Use Will we be able to use it easily? Quickly? YES
34461A: The industry’s only 100% drop-in, SCPI-compatible replacement for the 34401A DMM
Migrate with confidence:
Everything you depend on with
the 34401A and more
Like most 34401A DMM owners, you rely
on your DMM and you trust the answers
it gives you. Now, with the Keysight
Truevolt 34461A DMM, you can get all of
the advantages of the 34401A and more.
Now you can get faster answers and have
even more confidence in your results.
The best news of all? You can migrate
from the 34401A to the 34461A without a
hassle. No need to rewrite your software
programs or spend hours learning a
brand-new, complicated interface.
Use your existing programs: The 34461A
DMM is the industry’s only 100% drop-
in, SCPI-compatible replacement for
the 34401A DMM. Other DMMs may
claim 34401A SCPI compatibility, but
only a subset of SCPI commands are
implemented.
No long learning curve: The Truevolt
DMMs were designed by the same team
that created the 34401A. The team kept
34401A measurements, reliability and
familiarity in mind as they created the
Truevolt family of DMMs. So you can use it
without spending hours learning how.
The 34461A represents everything you
have known and trusted with your Keysight
DMM measurements for decades – it just
keeps getting stronger.

1. For DC: Specications are for 60-minute warm-up, aperture of 10 or 100 NPLC, and auto zero on. For AC: Specications are for 60-minute warm-up, slow AC lter, sine wave.
2. 20% overrange on all ranges, except 1,000 V DCV, 750 ACV, 3 A AC, and diode test.
3. Relative to calibration standards.
4. Add this for each °C outside TCAL ± 5 °C.
5. Specications are for sine wave input > 0.3% of range and > 1 mVrms. 750 ACV range limited to 8 x 107 Volt–Hz.
6. Low-frequency performance: three lter settings are available: 3 Hz, 20 Hz, 200 Hz. Frequencies greater than these lter settings are specied with no additional errors.
7. Specications are for 4–wire ohms function or 2–wire ohms using math null for offset. Without math null, add 0.2 Ω additional error in 2-wire ohms function.
8. Specications are for sinewave input > 1% of range and > 10 µA AC.
9. Specications are for the voltage measured at the input terminals. The 1 mA test current is typical. Variation in the current source will create some variation in the voltage
drop across a diode junction.
10. Actual measurement range and probe errors will be limited by the selected probe. Probe accuracy adder includes all measurement and ITS-90 temperature conversion errors
PT100 Ro settable to 100 Ω ± 5 Ω to remove the initial probe error.
11. Specications are for 60-minute warm-up and sine wave input unless stated otherwise. Specications are for 1-second gate time (7 digits).
12. Applies to sine and square inputs ≥ 100 mV. For 10 mV to < 100 mV inputs, multiply % of reading error x10.
13. Amplitude 10% – 120% of range and less than 750 ACV.
14. Square wave input specied for 10 – 300 kHz.
15. Specications are for using Math Null zeroing. High dissapation factor capacitors may show different results than a single frequency measurement. Film capacitors usually
have lower dissapation factors than other dielectrics.

1. For DC: Specications are for 60-minute warm-up, aperture of 10 or 100 NPLC, and auto zero on. For AC: Specications are for 60-minute warm-up, slow AC lter,
sine wave.
2. 20% over range on all ranges, except 1,000 V DCV, 750 ACV, 10 A DC, 3 A AC, 10 A AC, and diode test.
3. Relative to calibration standards.
4. Add this for each °C outside TCAL ± 5 °C.
5. Specications are for sinewave input >0.3% of range and > 1 mVrms. 750 ACV range limited to 8 x 10 7 Volt–Hz.
6. Low-frequency performance: three lter settings are available: 3 Hz, 20 Hz, 200 Hz. Frequencies greater than these lter settings are specied with no additional
errors.
7. Specications are for 4-wire ohms function or 2-wire ohms using math null for offset. Without math null, add 0.2 Ω additional error in 2-wire ohms function.
8. The 10 A range is only available on a separate front-panel connector. Add 2 mA base per amp or inputs > 5 A rms.
9. Specications are for sinewave input > 1% of range and > 10 µA AC.
10. Specications are for the voltage measured at the input terminals. The 1 mA test current is typical. Variation in the current source will create some variation in the
voltage drop across a diode junction.
11. Actual measurement range and probe errors will be limited by the selected probe. Probe accuracy adder includes all measurement and ITS-90 temperature
conversion errors. PT100 Ro settable to 100 Ω ± 5 Ω to remove the initial probe error.
12. Specications are for 60-minute warm-up and sine wave input unless stated otherwise. Specications are for 1-second gate time (7-digits).
13. Applies to sine and square inputs ≥ 100 mV. For 10 mV to < 100 mV inputs, multiply % of reading error x10.
14. Amplitude 10% – 120% of range and less than 750 ACV.
15. Square wave input specied for 10 – 300 kHz.

Measurement
considerations
All frequency counters are susceptible to error
when measuring low-voltage, low-frequency
signals. Shielding inputs from external noise
pickup is critical for minimizing measurement
errors.
Autozero OFF operation
Following instrument warm–up at a stable ambient temperature ± 1 °C and
< 10 minutes.
Add 0.0002% of range + 5 µV for DCV or + 5 mΩ for resistance.
Measurement settling considerations
High-power settling
Applying high-power signals (more than 300 Vrms, 500 VDC, 1A DC or
1 Arms) can cause self-heating in the signal-conditioning components.
These errors are included in the instrument specications. Internal
temperature changes due to self-heating may cause additional error on
other functions or ranges. The additional error will generally dissipate within
a few minutes.
DC blocking capacitor
Errors will occur in ACV and Frequency functions when attempting to
measure an input following a DC offset voltage change. The input blocking
RC time constant must be allowed to fully settle (up to 1 second) before the
most accurate measurements are possible.
External connections
Reading settling times are affected by source impedance, cable dielectric
characteristics, and thermal EMF of connections. Keysight recommends
the use of PTFE or other high-impedance, low-dielectric absorption
wire insulation for these measurements. To maintain low thermal EMF,
connectors and wires made of copper are recommended.
1. For power-line frequency ± 0.1%
2. For power-line frequency ± 1%, the NMR is 40 dB
For ± 3%, use 30 dB

Denitions
Specication (spec)
The warranted performance of a calibrated instrument that has
been stored for a minimum of 2 hours within the operating tem-
perature range of 0 – 55 °C and after a 60-minute warm up pe-
riod. All specications include measurement uncertainty and were
created in compliance with ISO-17025 methods. Data published
in this document are specications (spec) only where specically
indicated.
Typical (typ)
The characteristic performance, which 80% or more of manu-
factured instruments will meet. This data is not warranted, does
not include measurement uncertainty, and is valid only at room
temperature (approximately 23 °C).
Nominal (nom)
The mean or average characteristic performance, or the value
of an attribute that is determined by design such as a connec-
tor type, physical dimension, or operating speed. This data is not
warranted and is measured at room temperature (approximately
23 °C).
Measured (meas)
An attribute measured during development for purposes of com-
municating the expected performance. This data is not warranted
and is measured at room temperature (approximately 23 °C).
TCAL
The temperature at which the instrument was calibrated.
