M-520 Programmable Capacitance Decade
Capacitance decade is designed especially for calibration of capacitance ranges of multimeters and RCL meters. Due to its versatility it can be used in cal labs, repair centers and in production lines, where remote control of capacitance is requested. Main parts of the M-520 decade create relays with high current capability and capacitors with polypropylen dielectricum. Important feature is calibration procedure, which allows to recalibrate decade easily. Process of recalibration consists of measuring of partial capacitors inside the instrument and writing new calibration values into internal calibration memory. Calibration can be performed via RS-232 interface with calibration SW. Capacitance decade contains both calibration data for floating and grounding connection. Decade can be ordered as 19” module for easy assembling into a 19” rack. Module height is 3HE.
