Megger's DLRO10HD ohmmeter combines ultimate simplicity of operation with a rugged IP65 case and is designed for stable ground and bench operation. The unit is powered from either its rechargeable battery or line 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 DLRO10HD provides significantly enhanced compliance and is capable of delivering 10A into measurements up to 250mΩ and 1A into measurements up to 2.5Ω. The duration of each test may be up to 60 seconds.
The DLRO10HD is rated CAT III 300V. A range of test leads is available to suit the application.
The DLRO10HD provides five test modes each of which is selected through a simple rotary control: Rotary mode switch with bidirectional (current reversal with averaging cancels thermal EMFs), unidirectional, automatic, continuous and inductive modes.
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 stabilize 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 stabilizes. The operator decides when the result is stable and presses the ‘Test' button to terminate the test.
