• The latest circuit design permits the instrument to operate with the minimum of influence from earth voltage and earth resistance of auxiliary earth spikes.• Dust and drip proof. (designed to IEC 529 IP54)• Earth resistance value can be read directly from the scale.• Designed to meet IEC 61010-1 safety standard.• Capable of measuring earth voltage.• Small and lightweight. Shock resistant new case material.• 2mA measuring current permits earth resistance tests without tripping earth leakage current breakers in the circuit under test.• Lead wire connection to C and P terminals and proper auxiliary earth resistance can be checked by "OK" lamp. Lead wire connection to C and E terminals is good when "OK" lamp is illuminated. Inc. Accessories: 7095A (Earth resistance test leads) × 1set (red-20m, yellow-10m, green-5m), 8032 (Auxiliary earth spikes) × 1set, 7127A (Simplified measurement probe) × 1set, R6 (AA) × 6, Neck strap, Instruction ManualCarrying case : 9164(Carrying case[Hard]:4102A-H only)
