ZM2371/ZM2372 cover the frequency range of 1mHz to 100kHz, and ZM2376 covers 1mHz to 5.5MHz. 5-digit/6-digit resolution can be set*, so in addition to measuring various components at their actual operating frequencies, the frequency dependence of parameters can also be evaluated.
*ZM2371/ZM2372: 5 digits, ZM2376: 6 digits

The measurement signal level can be set with 3-digit resolution from 10 mVrms to 5 Vrms / 1 μArms to 200 mArms. In addition, the ALC (automatic level control) function enables constant-voltage/constant-current drive, allowing stable drive signals that account for the voltage/current dependence of the sample, achieving highly reproducible measurements.

Measurement time can be switched among 5 levels: RAP (Rapid), FAST, MED (Medium), SLOW, and VSLO (Very Slow). Selecting RAP enables fast measurement of 2 ms (1 kHz/1 MHz) and 10 ms (120 Hz). A fast, high-precision LCR meter helps improve the measurement efficiency of production lines and automatic inspection equipment.

Achieves high-precision measurement with basic accuracy of 0.08% and display resolution of up to 6 digits. Reliable measurement is indispensable for improving product performance and quality, from cutting-edge device development to component sorting on inspection lines.

Can measure the DC resistance of the winding resistance of coils and transformers. Inductance can be displayed as the primary parameter and the DC resistance measurement value as the secondary parameter at the same time.

● ZM2372

4-terminal contact check

(Additional time for contact check: 4 ms)

● ZM2376

Contact check, low capacitance check

Enables driving the sample only during the contact period.
This reduces contact damage caused by attaching and detaching samples when measuring large-capacitance capacitors. When measuring samples with short measurement history characteristics, measurement values can show large errors. With trigger circuit synchronized drive, the drive signal applied to each sample and the timing and phase relationship of signal acquisition are fixed, suppressing measurement value errors and greatly shortening measurement time.

By presetting the displayed value of the measured component, the deviation and deviation % from the preset value can be displayed. This can be applied to pass/fail judgment against tolerance specification values of components and temperature characteristic tests, etc.

Up to 14 BIN categories for the primary parameter*BIN categories; in the secondary parameter, measurement results can be sorted against one set of preset upper/lower limit values. Measured values can be sorted by deviation or deviation %, and judgment results are output via the handler interface*Output. In addition, depending on the judgment result, a beep sound may be emitted.
In remote control, using the limit judgment function, the upper and lower limit values (one set each) of the primary and secondary parameters can also be judged.
*ZM2371: Up to 9 classifications, not equipped with a handler interface.

Composite measurement is a function that can specify measurement conditions for up to 32 steps for one sample and comprehensively perform pass/fail judgment. The measurement frequency, measurement signal level, internal DC bias, measurement parameters, etc. can be set for each step, and measurement and limit judgment are performed for one set of upper/lower limits for the primary parameter and one set for the secondary parameter.
*A function unique to the ZM2376.

Standard interfaces for remote control. Production line integration and automated inspection systems can be supported without additional options.

Software that can set and acquire various measurement conditions and display measurement data is included as standard.
Measurement data can be obtained as CSV files, which is convenient for handling large amounts of data in research and development. In addition, sweep measurement supports impedance-frequency characteristic measurement.
