MEATEST M525 Programmable Capacitance Decade

The MEATEST M525 Programmable Capacitance Decade is designed for checking multimeters and simple LRC meter. It is suitable also for repair, adjustment and calibration of measuring instruments. Capacitance value is created via appropriate combination of physical capacitors. Capacitors are switched using special relays designed for high currents. Actual set values are displayed on high resolution TFT display. Comfortable user interface offers direct setting of capacity value, OPEN correction, grounding L terminal, user conversion curves setting and others.

The MEATEST M525 Programmable Capacitance Decade is equipped with an internal calibration menu that allows correcting any deviation of capacity value without opening the instrument and has it’s own re-calibration procedure. The procedure enables to correct any deviation in capacitance without any mechanical adjusting. Decade can be remotely controlled by a computer using standard RS232 interface. LAN, USB and GPIB interfaces are optional.

The MEATEST M525 Programmable Capacitance Decade is a precise capacitance decade box with range from 100 pF to 100 µF. Basic accuracy is 0.25 %. Best resolution on the lowest range is 1 pF. Capacitors are switched using special relays designed for high currents.
