The 3503 C HiTester is a capacitance measurement instrument that can measure capacity with constant voltage, making it ideal for testing large-value multilayer ceramic capacitors (MLCCs). The high-speed (4-ms) measurement performance of the standard comparator and phase-synchronous functions are particularly well-suited for high-speed MLCC measurement. Featuring a compact body with easy-to-read LED display, the 3503 allows the user to check settings at a glance, as well as provide easy operation. In addition, the device comes equipped with an RS-232C interface and external I/O as standard features, providing a lowcost means of building automated production lines and reducing production line tact time.

The 3503 can perform constant voltage measurement at 1 V or 500 mV, and supports voltage-dependent measurements. Select from a measurement frequency of 120 Hz or 1 kHz.

Except for turning the instrument's power on and off, all other functions for the 3503 can be controlled from a computer. This allows efficient handling when controlling or processing data in batches on a computer or when setting measurement conditions. The GP-IB interface can be installed as an option.
