DLRO 10HD Digital Microhmmeter

The DLRO 10 Digital Microhmeter is a lightweight robust instrument which is equally at home in the field or in the laboratory.

Typical applications for the DLRO 10 are:

• Switch and contact breaker resistance
• Bushbar and cable joints
• Aircraft frame bonds and static control circuits
• Integrity of welded joints
• Intercel connections on battery systems up to 600V 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 lighting conductor bonding

Features

• Four terminal resistance method shows the true resistance of the item under test
• Automatically applies forward and reverse currents which cancel out any out standing voltages across the sample under test
• Checks for undue noise during measurement, reducing the possibility of recording the incorrect results
• Automatically detects continuity in P and C circuits, preventing erroneously high reading to be taken due to high resistance contact
• Alpha-numeric keypad for entering test notes
• User selectable high and low limits
• Printer output and memory
