Megger DLRO 10X Repair and Calibration



TheMegger DLRO10 and Megger DLRO10X bring new standards to low resistance measurement. Both are fully automatic instruments, selecting the most suitable test current, up to 10 A dc to measure resistance from 0.1 µΩ to 2000 Ω on one of seven ranges. For users who desire more control over the measurement process, the Megger DLRO 10X uses a menu system controlled by a two-axis paddle to allow manual selection of the test current. The Megger DLRO10X also adds real-time download of results and on-board storage for later download to a PC. Both instruments are built into a strong, lightweight case that is equally at home in the field or in the laboratory. Light enough to be worn around the neck, they are small enough to be taken into areas which were previously too small to access. The Megger DLRO 10 uses a large, bright 4-1/2-digit LED display while the Megger DLRO 10X has a large, backlit LCD display.

 Megger Features:

• Accurate results in less than three seconds

• Auto current reversal cancels standing emfs

• Fuse protected to 600 V

• NiMH battery –  reduces weight

• 250 mW power limit (with optional override) to avoid heating the test sample

• Automatically detects continuity in potential and current connections

• Visible warning of high voltages present at the terminals

• Visible warning of current flowing in the test sample

• Multiple operating modes including fully automatic

• Alpha-numeric keypad for entering test notes (DLRO10X)

• User settable high and low limits (DLRO 10X)

• Auto ranging with Manual option (DLRO 10X)

• Printer output and memory (DLRO 10X)

The Megger DLRO10HD is a heavy duty low resistance ohmmeter combining rugged construction with accuracy and ease of use. It features an internal rechargeable battery and can also operate from a mains supply, even if the battery is completely flat.

• High or low output power selection for condition diagnosis
• Rechargeable battery or line power supply, continuous operation, even with dead battery
• 10 A for 60 seconds, less time waiting to cool, great for charging inductance
• High input protection to 600 V, inadvertent connection to line or UPS voltage will not blow a fuse
• Heavy duty case: IP 65 lid closed, IP54 operational (battery operation only)
• Rotary switch selects one of five test modes, including auto start on connection, giving ease of use

The Megger DLRO Digital Low Resistance Ohmmeters (DLRO®) are a family of highly accurate instruments that provide a simple, practical and reliable means of making low-resistance tests in the field. They also are ideal for production quality control. They operate on the four-wire measurement principle, thus eliminating lead and contact resistances. With basic accuracies of ±0.25% and resolution down to 0.1 μΩ, they are nonetheless designed to be rugged and portable for use at the job site. A variety of optional test leads and calibration resistance standards are offered for use withMegger DLRO’s.

Megger General-Purpose DLRO:2 Megger models specially designed for general-purpose testing applications are available. Each provides up to 10 amperes of test current for measuring resistances to 60 ohms with 1 μΩ resolution and ±0.25% accuracy.

Megger Dual-Pak General-Purpose Megger 247000 –  ThisMegger battery-powered DLRO 247000 features separate measuring and charger modules for maximum portability. The charger can be left in the shop, and the measuring module taken to the job site. It weighs less than 8 pounds and provides hours of testing.

Megger Single-Pak General-Purpose Megger 247001 This compactMegger DLRO instrument 247001 packages measuring circuits, rechargeable batteries and charger in one self-contained unit. Ruggedly built to handle the most demanding field applications, the Single-Pak is housed in a tough case with hinged, removable lid and carrying handle. This model also includes captive wing nuts.

Megger Single-Pak/Low-Range Megger 247002 TheMegger DLRO 247002 model provides an extra range, 0 to 599.9 μΩ, for applications requiring 0.1 μΩ resolution. It also features a current-reversing switch to average out any voltage offset in the test sample. Captive wing nuts are also standard.

Megger Low-Range/High-Current Megger 247100 and Megger 247101 These Megger instruments are used when a continuous test current of 100 amperes is required. These models include a separate 100 ampere current supply module with a modified standard battery-powered 10 ampere system. These combinations provide a sixth range, 0 to 599.9 μΩ, with the 100 ampere current. For 100 ampere measurements, an interconnecting cable from the 100 ampere current supply module is plugged into a special receptacle on the measuring module. When the 100 ampere range is not used, a jumper plug is inserted in place of the interconnecting cable. This feature allows the measuring module to be used as a standard battery-powered, 10 A instrument. Cat. No. 247100 meetsANSIC37.09, Test Procedure for AC High Voltage Circuit Breakers.
