DLRO2 2A Low Resistance Ohmmeter

The DLRO2 2 A Low resistance ohmmeter is a handheld instrument designed to give you 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 insunsulation resistance testers.
The DLRO2 can measure low resistance values across a wide range of applications, including railways, aircraft, and industry components. This tough device comes with a brand new ‘difference’ meter that allows repetitive measurements to be easily compared with an initial reference measurement. The difference meter also translates the percentage difference to a needle/pointer movement, making the changes clear to see.
If your applications require long test leads, then the DLRO2 can provide this without compromising test speed or safety. It has a dedicated long lead test to optimise the output, and this long test lead function is able to provide up to 1 A of test current into 4 ohms resistance. The DLRO2, with its optional cable reel test leads, is therefore ideal for testing wind turbine and avionic lightning protection applications.
Test Current Output @ Normal resistance test mode
Current ranges: 2 A, 1 A, 100 mA, 10 mA, and 1 mA
Maximum compliance output voltage: 3.24 V (1 A mode) 2.2 V (2 A mode)
Accuracy:
Normal and inductive mode: ±10 %
Long lead test mode: +10 % -0 %
at all battery conditions except with low battery indication
Low Resistance Measurement:
Overall resistance range: 1μΩ – 2000Ω
Max resistance across C terminals: 2 A with up to 1.1 Ω total resistance and 1 A with up to 3.2 Ω total resistance.
Basic accuracy:
Bi-directional test current mode: ±1% ±2 digits.
Uni-directional test current mode: ±1% ±10 digits.
Inductive mode or unidirectional mode will introduce an undefined error if an external EMF is present.
