Megger DLRO10HDX Low Resistance Ohmmeter

DescriptionMegger DLRO10HDX Low Resistance OhmmeterThe Megger DLRO10HDX Low Resistance Ohmmeter is engineered to measure resistance within a range of 0.1µΩ to 250mΩ with a maximum resolution of 0.1µΩ and an accuracy of ±0.2%. This powerful instrument can inject a test current of up to 10A into a conductor for up to one minute, making it ideal for measuring resistance across thick conductors, bonding, and welding. Its robust capabilities suit a variety of sectors, including rail and manufacturing.Operating the Megger DLRO10HDX is straightforward with its simple rotary switch and push buttons, which are designed for easy use even when wearing gloves. It offers specific test modes that allow for measurements in motors and generators, as well as across different metal combinations. The automatic mode conveniently performs a test as soon as the probes are connected, and the continuous mode is perfect for conducting multiple tests on the same conductor, such as on a production line.This ohmmeter can store up to 200 records in its internal memory, which can be easily recalled on its clear backlit LCD display. Additionally, saved files can be downloaded using the Megger PowerDB software. The instrument is supplied with a test lead pouch and user guide as standard. One of its key features is its versatile power supply, which allows it to run on either rechargeable batteries or mains power, facilitating both portable and extended use. Note that the instrument comes without test leads, but users can select either DH4-C probes or KC1 Kelvin clip probes from the drop-down menu.Megger part number: 1008-075Key FeaturesResistance range: 0.1µΩ to 250ΩAccuracy: ±0.2%Resolution: 0.1µΩFive test modes: Normal, automatic, automatic unidirectional, continuous, inductiveSimple rotary switch for ease of use10A test current injection capability200 reading internal memoryDownloadable with Megger PowerDB softwareRugged and durable in testing conditionsComparison of Digital Low Resistance OhmmetersFeatureMegger DLRO10Megger DLRO10XChauvin Arnoux CA6240Megger DLRO10HDMegger DLRO10HDXChauvin Arnoux CA6255Resistance Range0.1 µΩ to 2,000 Ω0.1 µΩ to 2,000 Ω5 µΩ to 400 Ω0.1 µΩ to 2,000 Ω0.1 µΩ to 2,000 Ω1 µΩ to 2,500 ΩTest CurrentUp to 10 AUp to 10 AUp to 10 AUp to 10 AUp to 10 AUp to 10 A (3 ranges)Test ModesManual, Auto, Continuous, InductiveManual, Auto, Continuous, Inductive, UnidirectionalManual, AutomaticManual, Auto, Continuous, InductiveManual, Auto, Continuous, InductiveInductive, Non-Inductive, Non-Inductive w/ auto triggerMeasurement ControlFully AutomaticFully Automatic / ManualManual, AutomaticFully AutomaticFully AutomaticManual, AutomaticMeasurement Speed<3s for forward and reverse current, average display<3s for forward and reverse current, average displayN/A<3s for forward and reverse current, average display<3s for forward and reverse current, average display<3s for forward and reverse current, average displayTest MethodSingle-cycle, reversing DC ratiometric measurementSingle-cycle, reversing DC ratiometric measurementN/ASingle-cycle, reversing DC ratiometric measurementSingle-cycle, reversing DC ratiometric measurementN/ATest Current Accuracy±10%±10%±10%±10%±10%±10%Test Current Stability<10 ppm per second<10 ppm per second<10 ppm per second<10 ppm per second<10 ppm per second<10 ppm per secondLead ResistanceMax. 100 mΩ for 10 A operationMax. 100 mΩ for 10 A operationN/AMax. 100 mΩ for 10 A operationMax. 100 mΩ for 10 A operationN/AVoltmeter Input Impedance>200 kΩ>200 kΩ>200 kΩ>200 kΩ>200 kΩ>200 kΩNoise Rejection<1% ±20 digits additional error with 100 mV 50/60 Hz<1% ±20 digits additional error with 100 mV 50/60 Hz<1% ±20 digits additional error with 100 mV 50/60 Hz<1% ±20 digits additional error with 100 mV 50/60 Hz<1% ±20 digits additional error with 100 mV 50/60 Hz<1% ±20 digits additional error with 100 mV 50/60 HzData TransferNoneReal-Time or from storage via RS232NoneNoneReal-Time or from storage via RS232NoneData StorageNone700 tests100 measurements200 test records200 test records1,500 measurementsMemo FieldNoneUp to 200 characters per test via integral keypadNoneNoneNoneNoneBattery Type7Ah NiMH rechargeable7Ah NiMH rechargeableNiMH rechargeable battery6V 7Ah sealed lead-acid6V 7Ah sealed lead-acidNiMH rechargeable batteryBattery Life1000 x 10 A tests1000 x 10 A testsNot specified>1000 Auto (3 sec) tests>1000 Auto (3 sec) testsNot specifiedBattery Charge Time2.5 hours to 90%, 4 hours full charge2.5 hours to 90%, 4 hours full chargeApprox. 6 hours8 hours8 hours2.5 hours to 90%, 4 hours full chargeOperating Temperature 5°C to 45°C (Full Accuracy) 5°C to 45°C (Full Accuracy)Not specified-10°C to 50°C-10°C to 50°C 5°C to 45°C (Full Accuracy)Storage Temperature-30°C to 70°C-30°C to 70°C-30°C to 70°C-25°C to 60°C-25°C to 60°C-30°C to 70°CTemperature Coefficient<0.01% per °C from 5°C to 40°C<0.01% per °C from 5°C to 40°CN/A<0.01% per °C from 5°C to 40°C<0.01% per °C from 5°C to 40°C<0.01% per °C from 5°C to 40°CMaximum Altitude2,000m (6562 ft)2,000m (6562 ft)N/A2,000m (6562 ft)2,000m (6562 ft)2,000m (6562 ft)Safety RatingCAT III 600 V (with DH6 leads)CAT III 600 V (with DH6 leads)CAT III 50 VIn accordance with IEC61010-1, CATIII 300V (w/ cover)In accordance with IEC61010-1, CATIII 300V (w/ cover)CAT III 50 VEMC RatingIP65 (case closed), IP54 (battery operation)IP65 (case closed), IP54 (battery operation)IP53IP65 (case closed), IP54 (battery operation)IP65 (case closed), IP54 (battery operation)IP53Dimensions (mm)220 x 100 x 237220 x 100 x 237273 x 247 x 280315 x 285 x 181315 x 285 x 181270 x 250 x 180Weight (kg)2.62.656.76.74What’s Included?Megger DLRO10HDX MicroohmmeterTest lead pouch (lid mounted)DLRO10HD user guide CDWarranty book **Available with or without DH4-C Duplex Handspikes – selectable above**The Megger DLRO10HDX Micro-Ohmmeter can be supplied without test leads or with two Megger 1.2m DH4 Duplex handspikes with indicator lights (6111-503).
