Description
The B&K Precision 309 lightweight portable meter tests earth ground resistance and earth AC voltage for new and existing buildings, structures, equipment, and electrical systems. When in use, the 2 milliAmp (mA) measuring current permits earth resistance testing without tripping ground fault breakers of the circuit under test. The data hold function with screen indicator allows the user to retain the measurements on the display for manual recording. The auto power-off feature turns off the meter after 3-6 minutes of continuous testing and the battery indicator notifies the user when batteries are low to ensure accurate measurements. Ground-resistance meters are used by electricians and contractors working in industrial, utility, and field servicing.
The B&K Precision 309 meter comes with a set of three test leads, two auxiliary earth spikes, a hard carrying case, and batteries. The meter is rated for indoor use, altitude up to 2,000m/6561ft., maximum relative humidity to 80 percent, and for use at pollution degree 2. Applicable safety standards are IEC/EN 61010-1 and Installation CAT III 200V.

Ground-resistance meters test the condition of a grounding system, and provide resistivity measurements in ohms. The meters are available in digital, analog, and clamp models. Grounding systems protect people and equipment, and provide a safe path for the dissipation of fault currents, lightning strikes, static discharges, EMI and RFI signals, and interference. Regular testing of a grounding system is important for safety and protection of equipment. For example, corrosive soil with high moisture content can degrade ground rods and connections in existing systems and increase the resistance of the system. Ground-resistance meters are used in conjunction with a variety of testing methods to troubleshoot intermittent electrical problems or as part of a regular maintenance plan.
