Data Acquisition Interface in DC Systems – ORM400

The ORM400 dual-channel picoammeter manufactured by Bentham is used as a data acquisition interface in DC systems using current generating detectors.

Broad dynamic range measurements with outstanding linearity can be achieved as this picoammeter offers short-circuit detector operation and an incredible six decades of gain.

The ORM400 dual-channel picoammeter, offered with an auxiliary voltage input, can be worked from the front panel or totally automated over the USB interface. Under-load and over-load flags are incorporated to enhance remote operation.
