Megger-DLRO2
The DLRO2 is a tough, hand-held 2 A low resistance ohmmeter. It’s designed to provide fast, accurate, repeatable measurements, even in electrically noisy locations. The DLRO2 is the latest in a long line of instruments to proudly display the Ducter™ brand, the
Ducter™ testers being as well-known and relied upon as Megger insulation resistance testers.
For the utility or industrial user, a high level of safety is provided with a CATIII 600 V/CATIV 300 V rating to IEC61010. In addition, the instrument can protect itself from inadvertent connections to up to 600 V without blowing a fuse, thereby avoiding essential time lost due to repairs or finding a replacement fuse.
When working outside, the IP54 rating ensures that neither rain nor dust will prevent testing.
The DLRO2 measures low resistance values across a wide range of applications, from railways and aircraft to the resistance of industry components.
Applications requiring long test leads are not a problem for the DLRO2 as it has a dedicated long lead test to optimise the output. The long test lead function is able to provide up to 1 A of test current into 4 ohms resistance. This makes the DLRO2, with its optional cable reel test leads, ideal for testing wind turbine and avionic lightning protection applications.
To allow testing of smaller inductive loads, the DLRO2 can apply 2 A for at least 15 seconds, made possible by the high-capacity built-in rechargeable batteries, together with a separate inductive load function. The batteries can be fully recharged in 2.5 hours, minimising down time.
Note: The DLRO2 is not ATEX/intrinsically safe rated and must not be used in explosive gas environments.
FEATURES
New Difference Meter
The DLRO2 is also equipped with a new innovative feature called a ‘difference’ meter. This allows repetitive measurements to be easily compared with an initial reference measurement. The Difference Meter translates percentage difference to a needle/pointer movement to make it visually easy to see change. New reference measurements can be set at the push of a button.
