Operated Stand Alone; Coverage Factor K=2.58 (99 % Confidence Level) - Fluke 52120A User Manual

Operated Stand Alone

The stand-alone specifications are stated for the accuracy of transconductance with a voltage input, or current gain with a
current input. These specifications do not include the errors of the instrument that provides the voltage or current signal to
the Product input. To get the absolute accuracy of the current output, combine the source and Product specifications with
the "root sum of squares" (RSS) method found in the 52120A Users Manual.
Up to ten 52120As (one master and nine slaves) can be chained together in stand-alone mode. Any additional slave units
are ignored by the control system.
