This Megger DLRO-10X digital low resistance ohmmeter uses a menu system controlled by a two-axis paddle to allow manual selection of the test current. DLRO10X also adds real-time download of results and on-board storage for later download to a PC. 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, they are small enough to be taken into areas which were previously too small to access. The DLRO 10X has a large, backlit LCD display. Uses a menu system controlled by a two-axis paddle to allow the user to manually select the maximum test current. DLRO 10X displays both forward and reverse measurements as well as the average of the two. DLRO 10X allows the user to set high and low pass limits, thereby enabling simple go-no-go testing. At the end of a test DLRO10X will store the test results, as well as any notes relevant to the test.

Normal mode initiates a test by pressing the Test button on the instrument front panel after connecting the test leads. Continuity of all four connections is checked, forward and reverse currents are applied.

Auto mode allows forward and reverse current measurements to be made and the average displayed simply by making contact with all four probes. This mode is ideal when working with the supplied handspikes. Each time the probes are removed and reconnected to the load another test will be performed without the need to press the test button on the instrument.

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 3 seconds until the circuit is broken.

Inductive mode is intended for use when measuring inductive loads. When measuring inductive loads it is necessary to wait for the voltage to stabilise. This means that the measurement could take a few seconds or several minutes. The test leads are firmly connected to the item to be measured and the Test button is pressed. The instrument will pass a current through the sample and wait for the voltage to stabilise. If possible the current will be increased. This procedure will be repeated until the voltage detected falls into the range 15 mV to 200 mV. The instrument will then continue to take readings, which will gradually decrease to the true value as the voltage stabilises further. The operator decides when the result is stable and presses the Test button to terminate the test. Measurement is made with forward current only.

Unidirectional mode, on DLRO 10X only, applies a current in one direction only. This does not enable any standing emfs to be negated but speeds up the measurement process. Test starts automatically when probes are connected.

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 d.c. 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
