Attractive color display. The display has a narrow viewing angle that works best at eye level. Easy to install: 1) current transformer 2) AC voltage lines 3) temperature sensor. Voltage readings are accurate. The current measured value requires a zero correction. My meter has parasitic current readings that cannot be reset. I tried rerouting the cables and moving the current transformer. Not too serious unless you measure very low power consumption. I use mine on a central AC compressor and the current error produces a constant 5W draw when the actual draw is zero. I checked, that's not a heating pan, just not zero. The timer is a mystery. Can it read actual overall performance during or time under load? Mine is stuck for 199.56 hours and not changing. The power factor reading may be correct. I don't have a good way of testing this. The KWH display is accurate enough to keep an eye on power consumption. The memory off function works. Most people will not use the power factor indicator. Maybe a peak power value would make more sense? Has a button to reset values to zero.
