The software also lets you generate tabular listings. The table gives a summary of a PQL 100's comprehensive capabilities. In use, a PQL100 can record up to 12 data channels, and you can program it for up to one year of operation. Color-coded LEDs indicate the mode of operation a unit is in. True RMS Note also that the system makes true-RMS measurements, and AEMC guarantees that a PQL100 will never miss a single cycle.
Frequency is tracked every cycle and is synchronized dynamically under phase-locked loop control.
As such, the frequency resolution is a close 0.01 Hz. Temperature drift is also minimized automatically. For current, the PQL 100 accommodates a range extending to 15 A, with a 70 A peak capability. Perhaps the only shortcoming of this unit is its limited voltage range. That aside, I think you'll find AEMC's PQL Series worth looking into.
