Introduction: Digital DC low resistance meter, also known as micro-ohmmeter, ohmmeter, equipotential tester, using the microprocessor technology, four-wire test, safety, precision and reliability.Mainly used to measure the wire resistance of cables, the contact resistance of switches, connectors, relays, the resistance of coils, motors, transformer windings, and equipment enclosures, lightning protection belts, ground beams, structures, cabinets, steel bars, water pipes, windows, guardrails, and heat dissipation Connection resistance test between metal components of objects such as devices, assembly lines, etc.It is widely used in telecommunications, electric power, meteorology, computer rooms, oil fields, power distribution lines, tower transmission lines, gas stations, factory grounding grids, lightning rods, etc.Digital DC low resistance meter is composed of host, monitoring software, test line, communication line, etc. The large-screen LCD display of the main unit is clear at a glance, and the port overload prevention function prevents the instrument from being burned out by misoperation.Store 500 sets of data, resistance measurement range: 0.001mΩ~ 300.0KΩ. The upper computer software has functions such as historical data reading, consulting, saving, and reporting. Technical Specification: Function:Mainly used to measure the wire resistance of cables, the contact resistance of switches, connectors, relays, the resistance of coils, motors, transformer winding and metal riveting resistance, the connection resistance test between metal components, the low-value resistance test, and the grounding grid Resistance test of connecting conductor, contact resistance test, etc.Detection method:Four-wire method testTest current:≥1AOpen circuit voltage:≤4.2VOverload protection:YPower:Measuring power≤8Wpower supply:DC 3.7V 2000mAhBacklight:Controllable gray and white screen backlight, suitable for dim placesDisplay Model:LCD LCD Size:72 mm×55mmInstrument size:187 mm×119 mm×50mmTest line length:About 60cm，red, black 1pcsmeasure time:About 2 times/secUSB interface:With micro USB interfaceCommunication line:micro USB 1pcsData storage:500 groups, "MEM" storage indication, display "FULL" symbol to indicate storage is fullData review:Data review function：“MR”symbol displayOverflow display:Over-range overflow function: "OL" symbol displayBattery voltage:Real-time display of battery power, reminding timely charging when battery voltage is lowAutomatic shut-down:"APO" indicates, automatic shutdown after 15 minutesPower consumption:Standby: about 100mA (backlight off);Turn on backlight: about 105mA;Measure：2A Max(backlight off)Weight:Instrument:480g(including battery);Test line：250gWorking temperature and humidity:-10℃～50℃；below 80%rhStorage temperature and humidity:-20℃～60℃；below 70%rhOverload protection:AC 220V/0.0001 second between C1-C2 P1-P2 ports, after overload protection, you need to restart the meter to test normallyInsulation resistance:More than 10MΩ(Between circuit and case 500V)Pressure resistance:AC 3700V/rms(Between circuit and case)Electromagnetic properties:IEC61010-4-3，Wireless frequency electromagnetic field≤1V/mSuitable for Safety Regulations:IEC61010-1, CAT III 600V, Pollution Level 2, JJG724-1991 "Determination of Direct Current Digital Ohmmeter", JJG166-1993 "Dialect Resistor Verification Regulation", "DL/T967-2005 Loop Resistance Tester and DC Resistance Fast Tester Verification Procedures Please click here Please click here Add to Cart Add to Cart Price $205.00$205.00 $255.00$255.00 Resistance Range 0.01mΩ～30.00KΩ 0.001mΩ～300.0KΩ Resolution 10uΩ 1uΩ Accuracy ±0.1%FS ±0.1%FS Data storage 500 sets 500 sets USB Data upload function NO ✓ Charging function ✓ ✓
