About Product

The NF ZM237x Series LCR Meters cover a wide frequency range, from the low-frequency region of 1mHz up to 5.5MHz. The ZM237x Series support a wide range of applications, from materials research to component production lines, by means of high-speed, high precision and low measurement fluctuation and stable measurement.

Product Features

  • Wide measurement frequency range
    • 1mHz to 100kHz (ZM2371 and ZM2372)
    • 1mHz to 5.5MHz (ZM2376)
  • High-resolution setting
    • Up to 5 digits for ZM2371 and ZM2372
  • Up to 6 digit for ZM2376
    • Wide range of test signal and ALC functions
  • The measurement signal level can be set at a resolution of 3 digits to 10mVrms to 5Vrms, or 1μArms to 200mArms. 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 2ms (1kHz/1MHz) or 10ms (120Hz) can be performed. This high-speed, high-precision LCR meter will help to improve the measurement efficiency of production lines and automatic inspection equipment
  • Built-in DC bias power supply
    • DC bias voltage: 0 to +2.5V (ZM2371 and ZM2372) and 0 to +5V (ZM2376)
    • The use of an optional DC bias voltage adapter makes ZM237x Series 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 on the winding resistance of 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
  • Versatile interface
    • ZM2371: USB interface, RS232 interface
    • ZM2372: USB interface, RS232 interface, GPIB interface, Handler interface
    • ZM2376: USB interface, RS232 interface, GPIB interface, Handler interface, LAN optional
  • Application Software for remote control and data acquisition is provided as standard

Product Functions

  • Contact check function
    • 4 terminal contact check (ZM2372)
      • In order to prevent measurement and selection errors due to poor contact between the measurement tip and components, the 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: 4ms) (See photo section)
    • Contact check and low capacitance check (ZM2376)
      • 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 on ZM2372 and ZM2376 and equipped with Handler Interface whilst 9 classifications max on ZM2371 and without Handler Interface equipped. 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 I 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 (ZM2376)
    • 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 and for temperature characteristic tests
  • Various correction functions are available including open correction, short correction, load correction and cable length correction
  • Setting and correction value memory (32 sets, switchable to be saved to non-volatile memory)
  • Monitor display (voltage and current)
  • Discharge protection
  • Application software (included as standard)
  • Sample program (C #, VB.NET) included
  • LabVIEW driver included (ZM2371 and ZM2372)
  • IVI instrument drivers included (LabVIEW drivers automatically generated on the LabVIEW system) (ZM2376)

Product Application

  • Impedance measurement on inductance, capacitance and resistance at spot frequencies
  • High-speed impedance measurements such as for lithium-ion batteries (single cell)
  • Polar components measurement such as electrolytic capacitors
  • DC resistance (DCR) measurement on the winding resistance of coils and transformers
  • Evaluation and research of dielectrics and magnetic materials
  • For integrating into component production lines and automatic sorting devices
    • With measurements at a maximum speed of 2 ms and with small deviation, correction functions to suppress the influence of the cable connecting to the sample, comparator and contact check functions and Handler Interface for automatic sorting, the ZM237x Series support a variety of line need. In note, both contact check function and Handler Interface are not available for ZM2371 (See photo section)
  • Support various impedance-frequency measurements by Application Software (Standard Accessory)
    • The Application Software capable of setting various measurement conditions and acquiring and displaying measurement data is included as standard. Measurement data can be acquired in CSV file format, making it convenient to process very large amounts of data for research and development. In addition, measurement of impedance frequency characteristics is supported by means of frequency sweep measurement (See photo section)
