autoranging

autoranging

[′ȯd·ō‚rānj·iŋ]
(engineering)
Automatic switching of a multirange meter from its lowest to the next higher range, with the switching process repeated until a range is reached for which the full-scale value is not exceeded. Also known as automatic ranging.

Autoranging and the ability to internally combine outputs deliver higher current at more voltage settings allowing them to cover a wider range of applications.
This ability is commonly known as 'Autoranging'--a term when a programmable source automatically offers a wide output range of both voltage and current to maintain full power output across a wide operation range.
Additionally, DirectStrain and intelligent autoranging test controls help eliminate the guesswork involved in selecting test settings that will be successful when testing over a wide range of temperature and stiffness.
Mort, "A computer-controlled variable light attenuator for protection and autoranging of a laser-induced fluorescence detector for capillary zone electrophoresis," Electrophoresis, vol.
introduced two high-power system power-supply families: the Advanced Power System (APS) family of 1-and 2-kW power models for demanding ATE applications, and the N8900 Series featuring programmable, 5-, 10-and 15-kW units with autoranging outputs for basic ATE applications.
Autoranging delivers increased resolution across diverse applications
For optimal accuracy, all models are autoranging. In data logging models, readings comprising up to 250 points can be stored and downloaded.
Operating from an 85-264V AC autoranging input, the PSU is available in both 12V and 24V versions and features fan cooling as standard, enabling it to deliver 200W continuously at the maximum permissible ambient temperature of 70[degrees]C, with a peak output capability of 300W.
