UPS III Loop Calibrators
Introduction
The Druck UPS III Series of loop calibrators can supply
power (source mode) and produce readings
(measure mode) to perform field calibrations on 2-
wire devices. The set-up menu enables the user to
"source" or "measure" in either voltage or current and
to perform continuity tests. These user instructions
include the operation, safety instructions and
installation requirements for loop calibrators.
