ZM serie
nF ZM series LCR meters cover 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
Product Description
Wide measurement frequency range and high-resolution settingsThe ZM2371 and ZM2372 have a measurement frequency range of 1 mHz to 100 kHz and a setting resolution of 5 digits. The measurement frequency range of the ZM2376 is 1 mHz to 5.5 MHz, and the setting resolution is 6 digits. It is suitable not only for measuring general electronic components, but also for evaluating the impedance of batteries and various materials.
Highly repeatable measurement results
The deviation of the measurement results of ZM2372 is about 0.01% or less, and the ZM2376 is even better. And highly repeatable measurement results are very important for impedance measuring instruments.
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 +2.5 V for ZM2371 and ZM2372, and 0 to +5 V for ZM2376 enables the measurement of polar components such as electrolytic capacitors. The ZM2376 can be used to measure impedance of battery by eliminating the DC voltage of it.
Also there is an optional DC bias voltage adapter for larger DC voltages. A bias voltage of up to ±40 V can be applied to the sample with an external DC power supply. So it is possible to test the voltage dependence of MLCCs (multilayer ceramic capacitors) as well.
