DC Resistance Tester Transformer DC Resistance Meter Tester with Touch Screen Introduction: Portable DC Resistance Tester, also known as transformer DC resistance tester, DC resistance rapid tester, grounding conductivity tester, adopts microprocessor technology, four-wire test, safe, precise and reliable. Is mainly used for measurement of transformer winding resistance, transformer winding resistance, ground down lead conduction testing, the wire resistance of the cable, switch, socket, relay contact resistance, winding, motor, shell and equipment, lightning protection zone, ground beam, structure, rack, steel, pipe, Windows, fence, radiator, pipeline connection between objects such as metal components resistance test. It is widely used in telecommunication, electric power, meteorology, machine room, oil field, electric power distribution line, tower transmission line, gas station, factory grounding grid, lightning rod and so on. Portable DC Resistance Tester is composed of a host, monitoring software, test line and communication line. Host handheld portable design is convenient for field application, with charging function without on-site power search, full-color large LCD display, clear at a glance, easy to use touch screen operation, port overload protection function. Large capacity storage 500 groups of data, resistance measurement range: 10.0 u Ω 50.00 K Ω, measuring accuracy: ±0.2%FS±10dgt. The upper computer software has the functions of reading, consulting, saving and reporting historical data. Specifications: Function mainly used for measurement of transformer dc resistance, transformer winding resistance, network connectivity, cable conductor resistance, contact resistance of switches, connectors, relays, winding, motor, transformer winding resistance and metal riveting resistance, metal component coupling between resistance test, low resistance testing, contact resistance testing, etc. Resistance range 10.0uΩ-50.00KΩ Resolution ratio 0.1 uΩ Precision ±0.2%FS±10dgt Detection method The four-wire test Measuring current 10A 、 5A 、 1A 、 0.1A 、 10mA 、 1mA Maximum short circuit current 10A overload protection Yes Self discharge Yes Power DC12.6v 2500mAh large-capacity lithium battery Charging function Yes Back light Yes, suitable for dark places Display mode LCD Full-color display Overflow shows The "OL" symbol is displayed when the overrange overflow occurs Touch screen operation Yes The LCD size Length and width: 108mm×65mm Size of instrument Length, width and height: 240mm×188mm×85mm The test line length 5 meters, 1 red, 1 black USB interface With USB interface Line of communication 1 USB communication cable Data storage 500 groups View Data Data access function Cell voltage The battery power is displayed in real time, indicating that the battery should be charged in time when the battery voltage is low Auto power-off Turn off the meter after no operation for about 15 minutes Power dissipation Standby: approx. 116mA (20% brightness) Measurement: 27W Max Weight Instrument: 1100g(including batteries) Test line: 850g Operating temperature and humidity - 10℃~40℃,Below 70%rh Storage temperature and humidity -20℃~60℃,Below 70%rh Insulation resistance More than 10 m Ω (circuit between the shell and 500 V) Withstand voltage AC 3700V/ RMS (between circuit and housing) Electromagnetic property IEC61010-4-3, wireless frequency electromagnetic field ≤1V/m Suitable for safety IEC61010-1 、 CAT Ⅲ 600V 、 Pollution level 2 、 JJG724-1991 <>, JJG166-1993 < Regulation of DC Resistor>>, <>
