The JOFRA ASC-400 Adjustment Manual provides step‑by‑step procedures for calibrating and adjusting the Advanced Signal Calibrator via USB.
The ASC-400 Advanced Signal Calibrator includes a built‑in adjustment function that is accessed through a simple ASCII protocol over the USB interface. This manual describes the terminal‑mode adjustment process, required temperature conditions, and the calibration menu.
Adjustment is performed by connecting the calibrator to recommended test equipment, entering the calibration menu, and following the prompts for each function (current, voltage, resistance, thermocouple, barometric pressure, etc.). The document also lists the necessary USB driver installation steps and the password needed to access the menu.
