Earth Bond Testers

AH Controls offers an Earth Bond Tester, AHCEBT-3015. It is designed to check the impedance of protective bonding of electrical equipment. It uses 4-wire technique to measure impedance of the earthing system in the equipment under test. The 4-wire measuring technique eliminates the resistance of the test leads and hence gives more accurate results. It is micro-controller based test equipment, which indicates voltage, current and calculated impedance on a 16 x 2 alphanumeric jumbo LCD display. The equipment is enclosed in a cold rolled mild steel cabinet coated with hard epoxy paint to give a long lasting finish. It gives an output of 15 V and 30. Specifications: supply voltage is 230 V ?10% 50 Hz AC; output current is 30 Ampere AC maximum; output voltage is 15 V AC variable; and impedance varies as per current and voltage (10 ohm maximum). Probes: four probes (clip type) are supplied with the equipment, two for the current and two for the voltage measurement. Two double wire probes also available for fast measurement of impedance.
