Abstract
A parasitic drain tester that measures a parasitic battery drain. A current measuring circuit includes a capacitor smoothing the current distribution within the circuit, a first interface connected to a vehicle power source and the capacitor, a second interface accommodating an outside connection for communication, a first processor connected to the second interface and the capacitor, the processor communicating with the second interface and performing analysis and calculation of the data received, and a converting unit connected to the processor, converting the signal received through the first interface from a first form to a second form. The first unit is connected to the current measuring circuit, and includes a memory storing information retrieved from the current measuring circuit through the second interface, and a second processor analyzing the information received from the current measuring circuit and providing instructions to the first processor through the second interface.
