A power load survey apparatus is disclosed with an electronic power sensor for detecting a power load in the form of a pulse signal, a collector cartridge detachably coupled to the electronic power sensor and having a memory for storing the pulse signal and the time of data collection. The time is obtained from a self-contained time keeping circuit. A memory and magnetic tape converting device is detachably coupled to the collector cartridge and includes a magnetic tape device for transferring and recording data from the memory of the electronic power sensor, and a standard clock 52. The time data obtained from the collector cartridge is time rectified to a standard time from the standard clock 52 each time the collector cartridge is coupled to the memory/magnetic tape converting device thereby insuring that the collector cartridge shows a correct time.
