About Megger DLRO10X
DLRO10 10 A digital low resistance micro-ohmmeter brings new standards to low resistance measurement (also known as the Megger Ducter test). It's a fully automatic instrument, selecting the most suitable test current, up to 10 A DC, to measure resistance from 0.1 to 2000 on one of seven ranges.
The DLRO10 uses a large, bright 4.5-digit LED display visible under all lighting conditions and help reduce errors in reading results.
The instrument is built into a strong, lightweight case that is equally at home in the field or in the laboratory and is light enough to be worn around the neck, enabling you to take it into areas which were previously too small to access.
To ensure you are able to choose the best test leads to suit their application, the DLRO10 may be purchased in one of two packages. The first option is supplied with a pair of duplex handspikes with 1.2 m (4 ft) leads, the second option is supplied without test leads to allow customers to order exactly the test leads they require from the accessory list.
The instruments are supplied as standard with a Lithium Ion battery pack. The battery packs are interchangeable so that an exhausted battery may be recharged using the external charger supplied while testing continues using a spare pack. Although full charging will take 4 hours, a fast charge mode allows the battery to be 90 % charged within 2 1/2 hours from a 12 V battery or from a standard 120/230 V AC supply via the supplied charger. The battery pack contains its own battery state indicator, which allows the charge state to be monitored, even without being connected to the instrument.
Exceptional Storage CapacityThe Megger DLRO10X offers ample internal memory, capable of storing up to 700 test results. This feature allows engineers and technicians to perform multiple tests on-site or in the lab without frequent data transfers, enhancing productivity and record-keeping efficiency.
Robust Safety and ComplianceWith a CAT III 300V safety rating and adherence to IEC61010-1 standards, the DLRO10X provides strong protection for users during high-current low-resistance tests. Its robust construction and high-quality test leads further contribute to safe and reliable operation in demanding environments.
Versatile Performance and Ease of UseSupporting both manual and automatic modes, the DLRO10X enables flexible operation for a range of applications. Instant readings, automatic current reversal, and an intuitive interface simplify testing processes. Its lightweight, portable design ensures comfort and convenience in the field.
FAQ's of Megger DLRO10X:
Q: How does the data storage feature of the Megger DLRO10X benefit users?
A: The device can securely store up to 700 test results, eliminating the need for manual result recording and simplifying data management, especially during extensive testing sessions. This facilitates efficient data retrieval and reporting, which is essential for field engineers and laboratory technicians.
Q: What safety features are included in the DLRO10X for user protection?
A: The Megger DLRO10X is rated CAT III 300V, offers over-range indication via its display, and is compliant with IEC61010-1 standards. These features collectively provide a safe testing environment, helping to protect operators from electrical hazards.
Q: When is manual versus automatic control mode used on the DLRO10X?
A: Manual mode allows users to initiate tests individually, ideal for situations requiring precise control. Automatic mode is preferred for repetitive measurements or batch testing, as it streamlines the testing process and saves time.
Q: Where can the Megger DLRO10X be deployed for testing?
A: Due to its portability, robust construction, and broad temperature and humidity tolerance, the DLRO10X can be used effectively in field locations, such as substations or construction sites, as well as in controlled laboratory environments.
Q: What is the process for powering the Megger DLRO10X?
A: The DLRO10X is equipped to operate on 8 AA NiMH rechargeable batteries or alkaline cells. A built-in battery charger ensures convenient recharging, and each full charge supports approximately one hour of continuous operation at maximum test output.
Q: How does the over-range indication function work?
A: When a resistance reading exceeds the instrument's maximum range, the DLRO10X alerts users through its display by showing an over-range indicator, ensuring clarity in test results and preventing potential misinterpretation.
Q: What are the benefits of using the Megger DLRO10X for low resistance measurements?
A: Offering high accuracy (0.2% of reading +2 digits), instant readings, and easy operation, the DLRO10X allows quick, reliable resistance measurements that are crucial for the integrity assessment of switchgear, cables, and busbar joints.
