The AVO / Megger DLRO10 Micr ohmmeter sets the standard for low resistance measurement. The DLRO10 ductor is a fully automatic instrument, selecting the most suitable test current up to 10A DC to measure resistance from 0.1 µΩ to 2000 Ω, on one of seven ranges.
The Megger DLRO10 Micr ohmmeter instrument is built into a strong, lightweight case that is equally at home in the field or in the laboratory. Light enough to be worn around the neck, this DLRO is small enough to be taken into areas that were previously too small to access.
Features:
-
Small, lightweight and portable - can be used in tight places, reduces the need for extra long leads and two person operation
-
Four terminal resistance method shows the true resistance of the item under test
-
Bright LED displays are easily visible under all lighting conditions and reduce human error
-
Automatically applies forward andreverse currents which cancel out any standing voltages across the sample under test
-
Checks for undue noise during measurement, reducing the possibility of recording the incorrect result
-
Automatically detects continuity in P and C circuits, preventing erroneously high reading to be taken due to high resistance contact
-
Battery module has a battery condition indicator allowing the user to check the state of spare batteries without connecting to the instrument
Applications:
The needs for accurate low resistance measurement are well known and very diverse. They range through Goods Receiving inspection of components to ground bonding and welded joints. Typical applications include, but are not limited to, making DC resistance measurements of:
-
Switch and contact breaker resistance
-
Busbar and cable joints
-
Aircraft frame bonds and static control circuits
-
Integrity of welded joints
-
Inter-cell connections on battery systems up to 600 V peak
-
Quality control of resistive components
-
Transformer and motor winding resistance
-
Rail and pipe bonds
-
Metal alloys, welds and fuse resistance
-
Graphite electrodes and other composites
-
Wire and cable resistance
-
Transmitter aerial and lightning conductor bonding
