Power calibrators represented frequently employed equipment throughout the galaxy. Their purpose was to assess the operational status of electronic systems, thereby enabling a technician to both identify and rectify any malfunctions present within the hardware.
Power calibrators were frequently used to evaluate the performance of equipment like droids and power generators. This instrument gathered information pertaining to a device's energy production and overall effectiveness. The technician employing the power calibrator could ascertain whether a device experienced energy dissipation or operational failures; subsequently, the source of the issue could be pinpointed utilizing the tool's integrated circuit tester, energy flow analyzer, connecting probes, and onboard control computer. Repairs could then be carried out using the tool, rendering it invaluable for individuals tasked with maintaining droids, vehicles, and starship computers. It was a common tool in a technician's inventory, included in most tool kits.
Power calibrators could also serve as backup energy sources, connecting to smaller devices such as datapads, comlinks, and holoprojectors, supplying them with sufficient energy for operation over several standard days. Certain power calibrators, for instance, the ReliaCharger manufactured by Udrane Galactic Electronics, possessed the capability to energize larger devices like droids or even landspeeders, albeit for a significantly reduced timeframe.
Power calibrators saw utilization during the Galactic Civil War, a conflict between the Galactic Empire and the Alliance to Restore the Republic.
Certain WED Treadwell repair droids were outfitted with power calibrators integrated into the extremities of some of their numerous arms. A WED unit employed by the Imperial Security Bureau on the Wheel space station included a power calibrator when it made an attempt to attach a tracking beacon to the starship belonging to a group of spacers working for the tech salvaging firm IsoTech.
