Overview / Features
This product is a capacitance mater card compliant with PCI Express bus and equipped with functions for measuring the electrostatic capacity (C) and coefficient of loss (D) of high-capacity ceramic capacitors at high speed and with high accuracy.
It is equipped with two channels of ports that can perform four-terminal measurement of capacitor capacity, and each channel can be set with a separate range and perform measurement separately. Windows device driver is supported with this product.
-
High-capacity ceramic capacitor measurement
- This product can measure the electrostatic capacity (C) and coefficient of loss (D) of 400pF to 1.4mF ceramic capacitors.
Measurement frequencies of 1kHz and 120Hz and measurement voltages of 1.0Vrms and 0.5Vrms are available.

Equipped with two channels of four-terminal measurement ports
- This product is equipped with two channels of ports that can perform four-terminal measurement of capacitor capacity, and each channel can be set with a separate range and perform measurement separately.
-
Capable of high-speed measurement, and capacity of measurement at constant voltage
- The electrostatic capacity (C) and coefficient of loss (D) can be measured in 2msec at a frequency of 1kHz and in 10msec at a frequency of 120Hz. And automatically adjusts the output voltage so the voltage applied to the measurement target (capacitor) becomes the set voltage. Consequently, it is possible to measure the capacity of the capacitor with a constant measurement voltage at all times without being affected by voltage drops caused by, for example, the cable.
-
Built-in trigger synchronization signal output, contact check, and correction functions
- Trigger synchronization signal output function
Applies voltage to the measurement target only during measurement, reducing characteristic changes due to heat generated by this target. Furthermore, the measurement signal is not applied when the connection is changed, reducing contact wear.
Contact check function
Checks whether all four terminals are connected during four-terminal measurement.
Correction function
Built-in open and short-circuit correction functions for eliminating measurement errors caused by the measurement jig or cable.
-
Windows support device driver
- Using the device driver API-TOOL makes it possible to create applications of Windows. In addition, a diagnostic program by which the operations of hardware can be checked is provided.
