Find out how accurate our measurements are.
Energy Monitoring is indicative rather than a precise measurement.
The accuracy of the energy use values will depend on the accuracy of the power factor of your machines and the accuracy of the current clamp measurement.
We have had our current clamps independently tested and in the range of 1 - 100 Amps, the accuracy is +/- 5.5%.
Energy monitoring in this way, however, is accurate enough to show you trends and anomalies.
For applications requiring more accurate data on energy monitoring, you can scale the energy use stated by FourJaw to that given by an accurately calibrated ammeter by changing the power factor of the machine.
