Digital Line Testers

The Digital Line Testers measure electrical resistance across dual ranges from 0-999 ohms and 1000-1999 ohms with automatic range selection and LCD display readout. The device operates on three AAA 1.5V batteries and maintains IP65 protection rating against dust and moisture ingress. Physical dimensions measure 140 x 69 x 34 millimeters with a total weight of 0.23 kilograms for field portability.

The OOM-4 model features measuring accuracy of ±0.5% or ±0.1 ohm tolerance with resolution capabilities of 0.1 ohm for lower ranges and 1 ohm for higher resistance measurements. Safety protocols limit maximum line testing current to 1 milliampere to prevent accidental detonation during circuit verification. The unit functions across temperature ranges from -20°C to +50°C at 100% relative humidity, with continuous measurement mode activated after 10 seconds of button release.

Military specialists utilize Digital Line Testers for verifying electric detonator circuit integrity before controlled demolitions. Combat engineers deploy these instruments during bridge demolition operations, obstacle clearance missions, and defensive position preparation where electrical firing systems require resistance validation. The continuous monitoring capability serves extended operations where detonator lines remain exposed during charge placement and concealment procedures.

Tactical Supply Pakistan delivers authentic line testing equipment that meets international explosive safety standards for military applications. The company maintains strict quality assurance protocols ensuring each tester performs reliably during critical demolition operations.

How does the automatic range selection function during multi-circuit testing operations?
The device automatically switches between 0-999 ohm and 1000-1999 ohm ranges based on detected resistance values, eliminating manual range adjustment during sequential circuit testing. When connecting to different detonator lines, the tester instantly selects the appropriate measurement range and displays results with corresponding resolution accuracy, allowing operators to rapidly verify multiple circuits without interrupting testing procedures.
