Product Overview: Megger DLRO2X Ducter Low Resistance Ohmmeter 2A
Megger DLRO2X Ducter Low Resistance Ohmmeter 2A
Manual and auto save results for export to USB (DLRO2X)
‘Difference Meter’ for quick data comparisons
Use very long test leads at 1 A using dedicated test mode
Safely test the resistance of inductive loads at 1 A
<600 V active protection against inadvertent live connections without blowing a fuse
Ideal for outdoor use with protection against dust and moisture to IP54
Industry standard safety rated at CAT III 600 V/CAT IV 300
For the utility or industrial user, a high level of safety is provided with a CAT III 600 V/CAT IV 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 optimize the output. The long test lead function is able to provide up to 1 A of test current into 3.2 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 1 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, minimizing downtime.
Easily select functions using the rotary dial.
Option to run the test in bidirectional mode or in unidirectional mode to save time and battery power.
The ability to view 3 results on the screen at any time makes it ideal for 3-phase systems.
Overcome the effects of standing EMF voltages using the bidirectional test mode. Forward and reverse results can be viewed on the secondary display.
Keeps testing as long as you can, with as many as 500 x 2 A – 3 second tests from a full charge.
Supplied with compact CAT III 600 V/CAT IV 300 V rated kelvin clip test leads.
Noise rejection range with Confidence Meter TM (DLRO2X only)
