ZM2376             
Measurement frequency 1mHz to 5.5MHz
Basic accuracy 0.08%
Measurement speed Max. 2ms
Equipped with contact check and Low capacitance check functions and a handler interface
 
NF's ZM series LCR meters cover a wide frequency range, from the low-frequency region of 1 mHz up to 5.5 MHz. Supports a wide range of applications, from materials research to component production lines, by means of high-speed, low measurement fluctuation.
 
ZM2376 covers frequencies from 1 mHz to 5.5 MHz. The resolution can be set to 5 digits or 6 digit* making it possible to perform measurements at frequencies actually used for a variety of components, in addition to evaluation of the frequency dependence of the parameters.
 
ZM2376: 6 digits
 
Wide range of test signal and ALC functions 
The measurement signal level can be set at a resolution of 3 digits to 10 mVrms to 5 Vrms, or 1 μArms to 200 mArms. In addition, by means of the automatic level control (ALC) functions, constant voltage and constant current mode can be set, making it possible to perform measurements with high reproducibility at a stable signal level that takes into account the voltage and current dependence of the sample.
 
High speed measurement Measurement speed is selectable from 5 levels: RAP (rapid) , FAST, MED, SLOW and VSLO (very slow). When set to RAP, high-speed measurement at 2 ms (1 kHz/1 MHz) or 10 ms (120 Hz) can be performed. This high-speed, high-precision LCR meter will help to improve the measurement efficiency of production lines and automatic inspection equipment.
 
DC bias voltage
The built-in DC bias power supply of 0 to +2.5 V for ZM2371 and ZM2372, and 0 to +5 V for ZM2376 enables the measurement of polar components such as electrolytic capacitors. With the ZM2376, high-speed impedance measurements, such as for lithium-ion batteries (single cell), are also possible. In addition, the use of an optional DC bias voltage adapter* makes it possible to apply a bias voltage of ± 40V to a sample enabling support for such measurements as the voltage dependence of high-capacity multi-layer ceramic capacitors.
 
Contact check and low capacitance check
Detects abnormally low capacitance, abnormal voltage and current, and can detect contact failures with little additional time.
 
Multi-measurement (ZM2376 only)
Multi-measurement is a function used for overall acceptance judgments by performing up to 32 steps for each sample. Multiple measurement conditions can be set for each step such as measurement frequency, measurement signal level, internal DC bias, and measurement parameters.
Measurements and limit determinations can be performed based on the set of upper and lower limits of the primary parameters and the set of upper and lower limits of the secondary parameters.
