DLRO10HDX
10 A Digital Low Resistance Ohmmeter
DLRO10HDX
10 Amp Digital Low Resistance
DESCRIPTION
Augmenting Megger’s DLRO10 and 10X range the
DLRO10HDX combines ultimate simplicity of operation with
a rugged IP65 case designed for stable ground and bench
operation and provides memory storage.
These units are powered from either rechargeable battery
or mains power making it suitable for continuous testing in
production line/repetitive use environments.
Rotary switch controls are simple and easy to operate in all
weather conditions and with gloved hands. A large, clear,
backlit LCD display is easy to read from a distance. The
DLRO10HDX provides significantly enhanced compliance
and is capable of delivering 10 A into measurements up
to 250 mΩ and 1 A into measurements up to 2.5 Ω. The
duration of each test may be up to 60 seconds.
The DLRO10HDX is rated CAT III 300 V provided the
optional terminal cover is fitted to the instrument. Details of
which can be found in the ordering information panel of this
data sheet.
The DLRO10HDX provides five test modes each of which is
selected through a simple rotary control on the Mode selection
rotary switch. All memory functions, delete, download to
PowerDB and recalling test results are also accessible via the
Range Selection rotary switch.
A simple control panel enables easy navigation for
configuration settings.
History of ‘Ducter’ testing
For over 100 years the ‘Ducter test’ has been used to describe
a simple test for measuring very low contact resistances
and “Ducter”, which is still used as a trade mark, was the
name originally given to the low resistance ohmmeter
manufactured by Megger. The name Ducter was registered
by Megger in June 1908 and ‘Ducter’ has since become the
industry standard.
ADDITONAL FEATURES AND BENEFITS
n Rugged case well suited to transportation with shoulder
strap and lead set pouch

n Operational ingress protection is IP 54 (battery power
only) ensuring protection from the elements
n 7Ah lead acid battery provides extended operation and
can be charged whilst operating from line power
n Rotary mode switch with bidirectional (current reversal
with averaging cancels thermal EMFs), unidirectional,
automatic, continuous and inductive modes
n Large, clear LCD display with backlight and contrast
adjustment
n Auto power off function conserves battery
