Adding to the features of Megger’s DLRO 10 and DLRO 10X ducter tester range the DLRO10HD digital low resistance micro-ohmmeter combines ultimate simplicity of operation with a rugged IP65 case designed for stable field and bench operation and provides memory storage.
This micro-ohmmeter can be powered from either a rechargeable battery or mains power making it suitable for continuous testing in production line or 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 DLRO10HD provides significantly enhanced compliance and is capable of delivering 10 A into measurements up to 250 mO and 1 A into measurements up to 2.5 O. The duration of each test may be up to 60 seconds.
The DLRO10HD is rated CAT III 300 V provided the optional terminal cover is fitted to the instrument, which can be ordered separately.
The DLRO10HD provides five test modes each of which is selected through a simple rotary control on the mode selection rotary switch. A simple control panel enables easy navigation for configuration settings.
The DLRO10HD measures low resistance values in applications ranging from railways and aircraft to resistance of components in industry.
The DLRO10HD is well suited to measuring thick conductors, bonds and quality of welding because of its 10 A range for resistance values up to 250 mO.
Electromagnetic noise induced into the leads can interfere with a reading. A noise symbol alerts the user and prevents a measurement when the instrument detects noise above its threshold.
Automatic unidirectional mode applies current in one direction only to speed up the measurement process. However thermal EMF resulting from dissimilar metal bonds
can cause lower accuracy. Test starts automatically when probes are connected.
Continuous mode allows repeated measurements to be made on the same sample. Simply connect the test leads and press the test button. The measurement is updated every three seconds until the circuit is broken.
Inductive mode is selected when measuring resistance on, for example, motors and generators. When measuring inductive loads it is necessary to wait for the voltage to stabilise as the inductive element is charged. Test leads are firmly connected to the device under test and the ‘Test’ button pressed. The instrument will pass the selected current through the sample continuously in one direction only and take repetitive readings that will gradually decrease to the true value as the voltage stabilises. The operator decides when the result is stable and presses the ‘Test’ button to terminate the test.
