Description
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. |
Step1:
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. |
