The motor driving apparatus according to an exemplary embodiment in the present disclosure may include: a controlling unit outputting a digital code; a converting unit converting the digital code into an analog driving signal; and a correction unit changing the analog driving signal at a predetermined ratio using a plurality of resistors. The user configures a plurality of rating elements by entering customized rating criteria used to calculate raw ratings for each of the rating elements. The sonde housing assembly at least partially defines a sonde interior and is further configured for receiving the pressure sensor body of a pressure sensor in a pressure sealed engagement. The bracket is mounted slidably on the base and connects to the stabilizing panel.
