LOAD SURVEY RECORDER FOR MEASURING ELECTRICAL PARAMETERS |
摘要 |
<p>LOAD SURVEY RECORDER FOR MEASURING ELECTRICAL PARAMETERS A survey recorder for measuring electrical loads and providing a magnetic tape record of data with time reference signals in format capable of providing computer compatible information. The data recording circuit utilizes a light emitting diode with a phototransistor to determine each quantum measurement by the meter, and a trigger circuit driven by the phototransistor feeds a solid state divider circuit which is programmable to provide various I/O pulse ratio outputs to the data recording head. A power outage circuit detects outages which are greater than a predetermined duration and provides distinctive pulses to a time recording circuit to effect a recognizable format on the magnetic tape which identifies the power outage.</p> |
