EC-3V AC Voltage Data Logger with Integral Phase Sequence/Rotation Checker
The EC-3V AC Voltage Data Logger allows engineers to quickly and cost-effectively monitor and resolve single & 3-phase voltage problems. It has an integral Phase Sequence/Rotation Checker. The voltage levels are stored with dates and times. With the back-up battery, the Electrocorder data logger can continue to record for a year.
Kit includes data logger, voltage input leads, USB lead, Electrosoft software and carry case.
Why is the Electrocorder better than other similarly priced competitors? The Electrocorder range use a constant sampling technique, unlike the single reading of competitors. When the loggers start to record, they sample every channel 16 times per cycle, a cycle is 16ms at 60Hz and 20ms at 50Hz. At the end of each averaging period, 3 quantities are saved for each channel, the True RMS average, the Max, which is the highest cycle value during the period and the Min, lowest cycle value. This means that it will record all the peaks and troughs which are one cycle or longer.
