The NF Corporation ZM2376 LCR meter covers 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.
Wide measurement frequency range and high-resolution settings
The ZM2376 covers frequencies from 1 mHz to 5.5 MHz. The resolution can be set to 5 digits or 6 digits 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.
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 +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.
DC resistance (DCR) measurement
It is possible to perform DC resistance measurements on the winding resistance of such equipment as coils or transformers.
The measured values of the inductance can be displayed in the primary parameters at the same time as the DC resistance in the secondary parameters.
Contact check function
In order to prevent measurement and selection errors due to poor contact between the measurement tip and components, ZM2372 performs a contact check measurement at four terminals to determine defects. This eliminates the output of defective products. (Additional time required for contact check: 4 ms)
Contact check and low capacitance check detects abnormally low capacitance, abnormal voltage and current, and can detect contact failures with little additional time.
Triggered synchronous drive
This function can be used to drive a sample for a period of time while contact is being made.
When performing measurements of large-capacity capacitors, it is possible to reduce the damage caused by the contact by removing the sample.
For samples with hysteresis characteristics, when measurements are performed in a short period of time, the measured values have larger fluctuations. By using triggered synchronous drive, the relationships between the time and the phase of the drive signal applied to each sample and the acquired signal are made constant. This suppresses deviations of the measured values ??and makes it possible to significantly reduce the measurement time.
Deviation display
When measuring a component, a preset value can be set and the deviation and the deviation % of the measured value compared with the preset can be displayed.
This can be useful for making acceptance judgments against standard component tolerance values as well as for temperature characteristic tests.
Comparator
A maximum of 14* primary parameters can be classified in bins, and measurement results can be sorted on a set of upper and lower limits that have been set by secondary parameters. Sorting is possible by measured value, deviation or deviation %, and the comparator results can be output to the handler interface*. In addition, a beeper can be turned on depending on the comparator results.
Using the limit determination function with the remote control interface, is also possible to determine the upper and lower limits (for each one set) of the primary parameters and secondary parameters.
Multi-measurement
When measuring a component, a preset value can be set and the deviation and the deviation % of the measured value compared with the preset can be displayed.
This can be useful for making acceptance judgments against standard component tolerance values as well as for temperature characteristic tests.
