Specification Brand : GOWE BulletPoint : Digital Earth Ground Resistance Tester (0 ~ 4000 Ohm) BulletPoint1 : earth resistance tester is used to measure the ground resistance of the inner electrical equipment; it presents the resistance between the exposed conductive part and electrical equipment. The tester applied 4 points testing method in order to eliminate the influence of the grounding resistance. That is to add current between the exposed conductive part and the all grounding point, then measuring the voltage of both points, finally calculate the resistance. BulletPoint2 : Performance Features:Measuring current:AC/5~30A; Measuring Resistance/0~200m¦¸; Measuring time/1~99s, synchronized display. Measuring time can be set arbitrarily.Alarming threshold 50-600m¦¸; Alert value can be set continuously. Qualified/Unqualified acousto-optic alert. BulletPoint3 : Technique Parameter:Parameter:Constant Current Grounding Resistance Tester; Output Current:AC:5~30A Current Accuracy:¡Ü5%¡À5 counts; Range of Resistance:0~200m¦¸/600m¦¸; Alert Resistance Value:0~200m /600m¦¸ continuously setting; Measuring Error: ¡Ü5%¡À5 counts; Measuring Voltage: 8V max; Isolated Voltage Transformer Capacitance: 300VA; BulletPoint4 : Time Control: 1s~99s/ continuously setting &manual; Alarming threshold: 50-600m¦¸; Display: Digital display: Measuring Judge; Qualified /unqualified, acousto-optic alert unqualified; Working Conditions: ¡Ü75% RH ,-20~50¡ãC; Weight: 11KG; Dimensions(W¡ÁH¡ÁD): 460mm¡Á340mm¡Á260mm; Power supply: AC 220V¡À10% 50Hz¡À5% BulletPoint5 : Carrying case with RTG cable ExternallyAssignedProductIdentifier1 : 0827674781406 ExternallyAssignedProductIdentifier2 : 827674781406 ItemName : GOWE Digital Earth Ground Resistance Tester (0~4000 Ohm) ItemPackageQuantity : 1 ItemTypeKeyword : ground-resistance-meters Manufacturer : Gowegroup ModelNumber : 880 PartNumber : GWE-1027679 PowerSourceType : Battery Powered ProductDescription : Digital Earth Ground Resistance Tester (0 ~ 4000 Ohm) ProductSiteLaunchDate : 2016-06-18T08:03:17.256Z SupplierDeclaredDgHzRegulation : unknown
