For Accurate Low Resistance Measurement Rent the Megger DLRO10HD

by Protec Tech Team February 08, 2017

Low resistance measurement is used to determine the condition of joined junctions like circuit breaker and relay contacts and terminals. When these joints weaken, carbon deposits, grease, dirt and other contaminants resulting in the resistance to increase, which in turn causes the junction to not efficiently carry the current, dissipating the power losses as heat. Thus, leading to further deterioration and eventual failure.

Detect Changes in Low Resistance Early with the Megger DLRO200-115

by Protec Tech Team May 04, 2015

Resistance (R) is the property of a circuit or element that determines, for a given current, the rate at which electrical energy is converted to heat in accordance with the formula W=I2R. The practical unit is the ohm. The low resistance measurement will indicate when degradation has or is taking place within an electrical device.

Megger DLRO10HD Digital Low Resistance Ohmmeter Suitable For Continuous Testing

by Protec Tech Team April 30, 2015

An ohmmeter is an electronic device that measures electrical resistance, such as that of a circuit component. Ohmmeters come with different levels of sensitivity; some are designed to measure low-resistance materials, while others measure higher resistance.

An ohmmeter functions by passing a constant current or voltage though an object, such as voltage from a battery, and then measuring the resulting voltage with an ammeter after it passes through the resistance. The higher resistance the material has, the less current will pass through it. An ohmmeter is typically not used to measure resistance across an entire circuit, but rather through different parts of the circuit, although it can be used to test that a circuit is not broken. Components of a circuit can be removed and tested individually for resistance.
