DLRO2

Ducter™ Low Resistance Ohmmeter 2 A

DESCRIPTION

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.

 New ‘Difference Meter’ for quick

data comparisons

 Use long leads at 1 A without compromising

test speed

 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

CATIII 600 V/CATIV 300

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.

DLRO2 Ducter™ Low Resistance Ohmmeter 2 A DLRO2 keeps you testing and produces reliable measurements To ensure the DLRO2 is always ready to test, the supplied fitted as standard HR6 rechargeable NiMH batteries can easily be swapped for non-rechargeable standard AA alkaline batteries to keep you testing. Hand held is not a compromise in quality of measurement. The DLRO2 provides 1% accuracy with a focus on repeatability making it ideal for repeated quality tests in production environments.

DLRO2 Ducter™ Low Resistance Ohmmeter 2 A Fast/long test leads mode: only has one user option, which is manual/auto. ‘Manual’ starts the test when the TEST button is pressed, ‘auto’ starts the test automatically when the instrument detects continuity. In this mode, the instrument settings are optimised for speed and, if needed, the use of very long test leads. The test current is only in one direction for speed, 1 A and above, resistance is only displayed in mΩ.
