The SD1000 phase meter offers superb accuracy, over a wide range of signal conditions. Conventional phase meters can become erratic when small levels of noise and distortion are present - the result is often unstable and incorrect phase readings. The SD1000 overcomes this by using Discrete Fourier Analysis (DFT) - to reject any noise and distortion without the need for tracking filters.
The SD1000 phase meter has totally isolated (floating) measurement inputs, allowing the user to connect anywhere in the circuit. This is very useful when the circuit under test does not have common grounds, eliminating accidental grounding and ground-loop currents. The user may choose voltage-voltage phase measurement, voltage to current phase measurement or current to current phase measurement, ideal for phase protection, power meters, energy meters and current transformer calibration
All measurements made with the SD1000 phase meter are traceable to National and International standards through the measurement standards of Powertek. The SD1000 is supplied with a certificate of conformance necessary for quality assurance standards such as ISO9001. A UKAS (independent measurement certification organisation) certificate is available.
