Fluke 7526A combines a precision signal source and an isolated measurement channel for laboratory and workshop calibration. It sources and measures DC voltage, current, resistance, RTD and thermocouple signals; two displays show source and measured results simultaneously. It supports nine RTD types, thirteen thermocouple types, nine stored setpoints per parameter and switch testing. Pressure checks require a compatible external 700P or 750P module and a separate pressure source. RS-232 and IEEE-488 interfaces support automation. Select MET/CAL software and pressure modules separately.
