MEASURE WITH UNQUESTIONED TRUEVOLT CONFIDENCE

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 derived and guaranteed per ISO / IEC 17025 industry standards.

WORRY ABOUT THE QUALITY OF YOUR DESIGN, NOT THE QUALITY OF YOUR MEASUREMENTS

Noise and injected current: Keysight Truevolt digital multimeters (DMMs) contribute less than 30% of the

injected current as alternatives. Compared with some lower-cost alternatives, Truevolt DMMs offer almost

100% less noise.

INPUT BIAS CURRENT:

Ideally, no current ﬂows into the measurement terminals of your DMM. In real measurement situations,

input currents create additional measurement errors. Truevolt DMMs take care of input bias current. Some

alternative DMMs offer 20% or more, poorer performance (some are too noisy to measure).

DIGITAL AC ROOT-MEAN-SQUARE (RMS) MEASUREMENTS:

For meters in this class, only Keysight uses digital direct sampling to make AC RMS measurements. The

result is a true RMS calculation technique that avoids the slower response of analog RMS converters used

in all other vendors’ 6½-digit DMMs. This technique allows for crest factors up to 10 without additional error

terms. This is a unique, patented technique — used only by Keysight.

WHAT TRUEVOLT TECHNOLOGY

MEANS TO YOU:

AC measurement accuracy is degraded

when signals have energy contained in

higher frequencies than a typical sine wave
