Review on πŸ’‘ bayite AC 80-260V Digital Power Energy Analyzer with Current Voltage Meter and Open-Close Split Core CT by Jay Buford

Revainrating 4 out of 5

Good little device at a great price

It's easy to use and easy to connect. I like the terminal block for connections. The device has two separate functions and two separate circuits. One is the Current Transformer (CT) which reads amps no matter what voltage is used to power it. The voltmeter circuit on the other pair of terminals is used for the other three functions. You can disconnect it from any voltage within the allowable range, and it doesn't have to match the voltage of the line being monitored. Note, however, that the wattage and energy readings assume you are using the same voltage as your current monitor. It's just multiplying volts by amps to get watts, and then by hours to get watt-hours of energy. So feeding the 120v side of the voltmeter and then clipping the CT to the 240 line will give you the correct amps, but the watts and watt hours are only half of what they should read. I'm not sure how accurate each unit is, but mine is showing low current. I hooked up an expensive meter to the same line and it read 3.09 amps while the Bayite meter read 3.02 or 97.7% of what it should have. Given the cost of this device, I can safely accept a 2.3% error rate. I'm annoyed by the flashing display when I turn it on. I have to hit the reset button every time. Found out it's Power Alarm. If you don't set an alarm value, it defaults to zero, so it "beeps" every time you turn it on. To stop blinking, simply set the power alarm value between 0.1 and 22.0 kW. Also, if you want to reset the energy value, you need to press and hold the reset button long enough for the number to flash. If you release it too soon, adjust the power alert setting on the wattage display instead. A bit confusing at first.

Pros
  • Easy to use
Cons
  • Lots of things
