Very Accurate and Convenient
1 of 1 found this helpful I checked the readings against other watt meters and against power using devices with known wattages, and found the readings to be very accurate - possibly within 1 per cent. The meter gives real wattages and not just volt amperes in that it accurately corrects for inductive loads with low power factors. I tested loads with power factors between 0.35 and 1.0, and it gave consistently accurate results. Although the meter does not display the volt-ampere and power factor reading, you can easily get it by multiplying the volts by amps, and then dividing watts by volt-amperes to get power factor. I was at first skeptical about how accurate the clamp-on current transformer coil would be compared to regular current coils, but found it to be just as accurate, and much more convenient in that you do not have to disconnect and reconnect circuit breaker wires in distribution boxes to get the current transformer coil on it. Depending on your application and testing usage, it may be useful to solder on additional wire lengths and test clips for easier connections.
