Abstract
The present invention relates to a digital DC voltage and horse power multimeter device unitized in determining the voltage and horse power on a locomotive system. The meter is permanently mounted onboard the locomotive and is capable of instantaneous determination of the voltage reading and horse power to provide real time evaluation of the locomotive's functions. The meter is built into the voltage test panel, replacing the test receptacles, and is designed to prevent operator error in that a voltage range is not required to be set before the multimeter reads a desired voltage. The meter is capable of reading the main generator, a load shunt test millivoltage, and is capable of determining the horse power of a locomotive system. The invention is therefore a device for metering electrical energy and calculating the horse power on a locomotive system which is permanently installed which operates off the existing 74V DC accessory power and is safer due to the absence of manual range settings.
