Usually, in 7-21 working days, customers can get the orders after issuing the order. However, we will do our best to dispatch it as soon as possible. If you are urgent, please make us informed it in time. & The 4105A-H digital tester performs three-pole earth resistance and two-pole voltage testing of electrical equipment and systems wiring and grounding to reduce power quality issues and avoid safety hazards. The meter is small and lightweight, with shock-resistant case material and taut-band movement. The OK light verifies proper connection between auxiliary earth resistance and lead wire connection to terminals. The tester warns the user when the resistance of auxiliary earth spikes exceeds tolerance. Ground-resistance meters are used by electricians and contractors working in industrial, utility, and field servicing.The 4105A-H has an IP 54 rating for limited ingress of dust and protection against water splashes and drips. Safety ratings are CE compliant, designed to safety standard IEC 61557, and rated as CAT III 300V. The test kit includes set of three test leads (red 20m, yellow 10m, green 5m), one set of measurement probes, two auxiliary earth spikes, neck strap, and a hard carrying case that holds the instrument and all testing accessories. Specifications Earth resistance range 0-20 0-200 /0-2000 Earth voltage range 0-200V AC (50, 60Hz) Accuracy + or - 3% full scale Withstand voltage 3700V AC for 1 minute Power source (6) AA 1.5V batteries (included) Weight 600g Dimensions 105 x 158 x 70mm (H x W x D)H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back. 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 di
