  • Description
    The UNI-T UT275 earthing pliers belong to the middle class in terms of technology and accuracy. It can quickly and safely measure the grounding system without disconnecting the lightning conductor terminals from the ground line of the circuit and also without the need for auxiliary electrodes. sidewalks and asphalt). It cannot be used with single-lead lightning conductors (without the use of an auxiliary probe), on the contrary, the more leads the collector system has, the more accurate the measurement. It is a very reliable, robust device from a quality manufacturer with the best price / performance ratio on the market. It can measure resistance from 0.01 Ω to 1000Ω and leakage currents from 0 mA to 30A. Current measurement should only be performed on ground cables, not on power cables, as this could affect the magnetic properties of the clamp terminals and thus the accuracy of the resistance measurement. The magnetic circuit of the jaws contains the voltage and current loop of the measuring transformer. It is possible to set an optical and acoustic alarm for current and resistance limits. The device is designed to meet the safety standards IEC61010-1 and IEC61010-2-032. Complies with CATIII 300V category and safety standards for level II pollution. It fully complies with the ČSN EN 61557 standard. It contains a memory storage for 30 sets of measurements. The calibration protocol must be ordered separately, thus extending the delivery date by 1-2 weeks.
