HP U1730C

Agilent U1730C Series
Handheld LCR Meters
Take your expectations higher with
the latest LCR meters
Data Sheet
Agilent’s U1730C Series handheld LCR meters allow you to
measure at frequencies as high as 100 kHz—a capability typically
found only in benchtop meters. Get measurements done faster
using the one-touch automatic identification function button which
displays component type and more detailed component analysis
such as Z, ESR, and DCR. Ideal for testing on the go, these LCR
meters operate on a battery that lasts up to 16 hours. With the
U1730C Series that is built for your convenience, you can perform
quick and basic LCR measurements at an affordable price.
It’s a good time to retool your expectations in handheld LCR
meters.
Features
Key features
Frequency up to 100 kHz
Detailed component analysis
• 20,000 counts resolution
The test frequency now extends
as high as 100 kHz, providing more
flexibility to test a wider range of
components. A higher test frequency,
for example 100 kHz, is useful for
applications such as testing aluminum electrolytic capacitors used in
switching power supply circuits.
The handheld LCR meters allows
you to test various component types,
including secondary components
of Dissipation Factor (D), Quality
Factor (Q), and Angle Indication of
Impedance (θ). This new handheld
series also includes other functions that result in a more detailed
component analysis. For example, the
built-in Equivalent Series Resistance
(ESR) function helps you better
understand the inherent resistance
behavior typically found in capacitors
across selected frequencies. DCR is a
built-in DC resistance measurement
that eliminates the use of a separate
digital multimeter (DMM) for component test.
• 0.2% basic accuracy
• Wide LCR ranges with three to five
selectable test frequencies (up to
100 kHz for U1733C)
• Auto identification (Ai)
automatically determines and
displays component type and
measurements
• Detailed component analysis with
DCR, ESR, Z, D, Q, and θ functions
• Battery life of 16 hours/
AC-powered
• IR-to-USB connectivity for data
logging to PC
Automated identification
With Ai the testing and measuring
experience is easy; eliminating unnecessary trial and error time—with just
a single push of a button. This unique
feature automatically specifies L, C,
or R with parallel and series mode,
without the need to manually change
buttons.

U1731C/U1732C/U1733C Electrical Specifications
Accuracy is given as ±(% of reading + counts of least significant digit) at 23 °C ± 5 °C, with relative humidity less than
80%. Please refer to the User Guide about the measuring mode specified for each range of L/C/R, series or parallel mode.
Measurements performed at the test socket and necessary Open and Short corrections must prior be done. The accuracy
is verified by design and specified type tests.

b. Resistance is specified to Q < 10 and D > 0.1, otherwise the accuracy is (AZ + Offset) x √ 1 + Q2
c. Equivalence Series Resistance (ESR) measurement is determined by impedance measurement and range. The maximum
display is up to 199.99 kΩ and the accuracy is (AZ + Offset) x √ 1 + Q2
