Features
Key features
– 20,000 counts resolution
– 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
Frequency up to 100 kHz
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.
Automated identication
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.
Detailed component analysis
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 compo-
nent test.
