Digital Earth Resistance PAT Tester for Houses and Buildings
PAT Tester (resistance/voltage) for houses and buildings
This PAT Tester is used to measure lightning-arresters or ground connection lightning-arresters for all kinds of buildings. earth tester possesses a hermetic case and fulfills all the VDE 0413 safety requirements for technical service operators. The PAT Tester is appropriate for measuring ground electrodes, lightning-arresters or little earth resistance systems as well as for measuring power resistance, conductive elements and coupling components.
Modern switching circuits reduce the influences of both pressure and earth resistance of the surrounding earth electrodes. Calibration of the earth tester with the adjoining control mechanism avoids the loss of precision at measuring.
Frequency control of 850 Hz avoids the influence of scattered currents of the net and its harmonic elements. Besides, this tester has a filter incorporated to delete distorted signs. The PAT Tester is delivered with the factory calibration however it can also have ISO calibration certificate.
