Manufacturer: B&K Precision Corporation Brand: B&K Precision Model: 309

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. Specifications Measuring frequency 820Hz at approximately 2mA Earth resistance ranges and resolutions 0 - 20Ω range (0.01Ω resolution); 0 - 200Ω range (0.1Ω resolution); 0 - 2000Ω range (1Ω resolution) Earth resistance accuracy + or - 2% reading + 2 digits Earth voltage range 0 to 200V AC (40-500Hz) Earth voltage accuracy + or - 1% reading + 2 digits or + or - 0.1Ω, whichever is greater Temperature range 0 to 40 degrees C/32 to 104 degrees F Power source (6) 1.5V AA batteries (included) Weight 410g/0.9lbs.

Manufacturer: AEMC Brand: AEMC Model: 3640 Kit-300ft

The AEMC 3640 portable digital ground resistance tester with 300 ft. leads performs 3-point fall-of-potential ground resistance testing and 2-point continuity tests on bonding, and is suitable for rugged use by maintenance crews performing multiple tests. The compact unit is well-suited for a range of applications, such as testing single rod and small ground grids at telecommunications sites, cellular towers, and for lightning protection systems, grounded equipment, and new construction. The tester is designed for ease of use, with “connect–press–read” operation, three color-coded terminals, and a large Press to Measure button. The large LCD screen indicates low battery status, over-range, and lead reversals. The tester displays direct readings from 10 to 1999Ω. It is engineered to reject high levels of interference in difficult conditions, such as high stray currents that can affect accuracy. Response time is approximately six seconds for a stabilized measurement. Ground-resistance meters are used by electricians and contractors working in industrial, utility, and field servicing.The AEMC 3640 double-insulated tester with CE mark meets or exceeds IEC mechanical and safety specifications for shock, vibration, and drop tests. It is fuse-protected and can withstand 250V RMS in the event of a system fault with spikes of 3000V AC or 1000V DC. Safety ratings include EN61010-1, CAT III, and pollution degree 2. The tester kit includes two 300ft. color-coded leads (one red, one blue), two 100ft. leads (one green, one black), four 14.5" T-shaped auxiliary ground electrodes, five spaded lugs, and a 100ft. tape measure, a carrying case for the tester, and a carrying case for the kit accessories. Specifications Operating frequency 128Hz square wave Measurement range 0 to 19.99Ω/20.00 to 199.9Ω/ 200.0 to 1999Ω Resolution 10mΩ/100mΩ/1Ω Test current 10mA/1mA/0.1mA Accuracy + or - 3% of reading + 3ct/ + or - 5% of reading + or - 3ct Operating temperature ra...
