Megger DLRO10HD 10A Low Resistance Ohmmeter
Product Description
Equally at home in the laboratory, the workshop or in the field, on the bench or on the ground, Megger’s new heavy duty DLRO10HD low resistance ohmmeter combines 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.
Overview
- 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: IP65 lid closed, IP54 operational (battery operation only)
- Rotary switch selects one of five test modes, including auto start on connection, giving ease of use
- Rugged case well suited for transportation and includes a lead set pouch
- Removable lid facilitates easy test lead connection
- Operational ingress protection is IP54 (battery power only) ensuring protection from the elements
- 7Ah lead acid battery provides extended operation and can be charged whilst operating from line power
- Rotary mode switch with bidirectional (current reversal with averaging cancels thermal EMFs), unidirectional, automatic, continuous and inductive modes
- Large, clear LCD display with backlight and contrast adjustment
- Auto power off function conserves battery
The DLRO10HD features two ranges with extended compliance. Effectively there are two 2.5 Ω and two 250 mΩ ranges one low power, and one high power. The chart below shows the power output curves for the two 250 mΩ ranges. Each range provided 10 µΩ resolution allowing the user to make comparative measurements at either 0.25 Ω or 25 Ω maximum outputs.
