NF ZM2371 LCR Meter
A LCR meter measures impedance (inductance, capacitance and resistance) at spot frequencies. It is used for testing components and materials in R&D applications and in component manufacturing.

  • Basic accuracy 0.08%
  • Measurement frequency 1mHz to 100kHz
  • Measurement speed Max. 2ms
  • Equipped with 4-terminal contact check function and a handler interface
Primary parameters
Displays measured values for Lp, Ls, Cp, Cs, Rp, Rs, |Z|, |Y|, G.
Automatic selection is possible.
Secondary parameters
Displays measured values for Q, D, X, B, Rs, Rp, G, Lp, Rdc (DC resistance).
Automatic selection is possible.
Measurement frequency
Select one of the four frequencies (120 Hz, 1 kHz, 10 kHz, and 100 kHz) or input a numeric value (5-digit resolution).
Equivalent circuits(Primary parameter)
For the L, C, and R, specify the equivalent circuit. Automatic selection is possible.
Measurement range
Automatic selection (AUTO) and manual selection (HOLD) can be switched.The default setting is automatic selection.
Measurement speed
Switchable between 5 levels from 2 ms to 501 ms.
ZM2372 Functions to improve yield and sorting efficiency
Comparator function and handler interface
The comparator result can be output to the handler interface.
4-terminal contact check function
Detects defective contact of four measurement terminals.
Basic accuracy: 0.08 %, display resolution of 6 digits (max.)
Measurement speed: Max. 2 ms at 1 kHz
Measurement speed is selectable between 5 levels: RAP (rapid) , FAST, MED, SLOW and VSLO (very slow). When set to RAP, high-speed measurement at 2 ms (1kHz) or 10ms (120 Hz) can be performed.
Measurement frequency: 1 mHz to 100 kHz, 5-digit resolution
Measurement signal level: Max. 5 Vrms, 3-digit resolution
Measurements parameters: Lp, Ls, Cp, Cs, Rp, Rs, |Z|, |Y|, G, Q, D, X, B, Rdc
Internal DC bias: 0 V to +2.50 V
Constant-voltage/constant-current drive (ALC:Auto Level Control)
DC resistance measurement
4-terminal contact check function and a handler interface for production lines (ZM2372)
ZM2372 is equipped with contact check function to prevent mis-measurement or incorrect sorting due to defective contact between the measurement tip and component. It checks contact with 4 measurement terminals, and if a contact defect occurs, it halts measurement/sorting and determines the contact defect. This function contributes to improved yield.
Checks whether there is continuity along the dotted lines (contact check).
Determines there is a defect if contact is defective.
Once the contact failure is detected, ZM2372 allows the measured value “NC” to appear without performing normal measurement.
The additional time necessary for 4-terminal contact check is approx. 4 ms.
Step2: Measures along the dotted lines (main measurement)
Other functions:
Correction functions (Open, Short, Load and Cable length), Deviation measurement, Comparator function etc.
