Patent ID: 7619420

Claim:
An apparatus comprising: a single measurement device for simultaneously measuring a first capacitance and a second capacitance; a display module for simultaneously displaying at least a first numerical value based on the first measured capacitance and a second numerical value based on the second measured capacitance, wherein the first measured capacitance is provided by a first portion of a motor run capacitor, the second measured capacitance is provided by a second portion of the motor run capacitor, and the first measured capacitance and the second measured capacitance are different; a selector for establishing a first range of measurable capacitances for the first measured capacitance and establishing a second range of measurable capacitances for the second measured capacitance; the selector being further operable to select a first precision for the first numerical value and a second precision for the second numerical value; a common port used in measuring the first measured capacitance and the second measured capacitance; a common lead connected to the common port and configured to attach to a common connector of the motor run capacitor; a first port used in measuring the first measured capacitance; a first lead connected to the first port and configured to attach to the first portion of the motor run capacitor; a second port used in measuring the second measured capacitance; a second lead connected to the second port and configured to attach to a second portion of the motor run capacitor; and a safety circuit connected to the common port, wherein the safety circuit includes a fuse.
