Description

Handheld DC Resistance Tester Transformer DC Resistance with 500 groups Data Product Overview Handheld DC resistance tester, also known as transformer DC resistance tester, DC resistance fast tester, grounding conductivity tester, using microprocessor technology, four-wire method of testing, safety, precision and reliability. Mainly used for measuring the resistance of transformer winding, transformer winding resistance, grounding lead wire conductivity test, cable wire resistance, switch, connector, relay contact resistance, coils, motors, and equipment shells, lightning straps, ground beams, construction, cabinets, steel, water pipes, windows, guardrails, radiators, assembly lines, and other objects of the object of the linkage between the metal components of the resistance test. Widely used in telecommunications, electric power, meteorology, engine room, oilfield, power distribution lines, tower transmission lines, gas stations, factories grounding network, lightning rods. Handheld DC resistance tester consists of a host computer, monitoring software, test line, communication line and so on. Host handheld portable design for easy field application, with charging function without the need to find power on site, full-color LCD display, at a glance, touch-screen operation is convenient and easy to use, the port anti-overload function. Large-capacity storage of 500 groups of data, resistance measurement range: 10.0uΩ-50.00KΩ, measurement accuracy: 0.2%. Upper computer software with historical data reading, access, save, reports and other functions. Technical Parameters Functions 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 Power DC12.6v 2500mAh large-capacity lithium battery Display mode Full colour LCD display Overload protection Yes Backlight Yes, suitable for dark places Touch screen operation Yes LCD size Length and width: 108mm×65mm Size of instrument Length, width and height: 240mm×188mm×85mm The test line length 5 metres, 1 red, 1 black Interface USB interface Operating temperature and humidity -10℃～50℃; 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) Withstanding Voltage AC 3700V/rms (between circuit and case) Power Consumption Standby: Approx. 120mA (20% brightness) Measurement: 27W Max Self discharge Yes Charging function Yes 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 Electromagnetic property IEC61010-4-3, wireless frequency electromagnetic field ≤1V/m Suitable for safety IEC61010-1、CAT Ⅲ 600V、Pollution level 2、JJG724-1991 <<VERIFICATION Regulation of DC Digital Ohmmeter>>, JJG166-1993 <<Verification Regulation of DC Resistor>>, <<VERIFICATION Regulation of DL/T967-2005 Circuit Resistance Tester and DC Resistance Rapid Tester>>
