Detect Problems with Electrical Connections using a DLRO

by Protec Tech Team April 30, 2018

The resistance of an electrical connection increases over time due to temperature, cycling, and other environmental stresses. The degradation of these connections can result in excessive losses due to heating and operability issues . Periodic testing of contact resistance and/or other electrical bonds can help to identify changes in the condition of contacts and other electrical connections.


AEMC Ohmmeters are Available for Rent from Protec

by Protec Tech Team September 28, 2017

Ohmmeters are an electronic device that measure electrical resistance, and come with different levels of sensitivity. Some are designed to measure low-resistance materials, while others measure higher resistance. The higher resistance the material has, the less current will pass through it.Contact Us Now

An ohmmeter is typically not used to measure resistance across an entire circuit, but rather through various parts of the circuit, although it can be used to test that a circuit is not broken.

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.


Many Industries Benefit By Using Megger DLRO 600 Digital Micro-Ohmmeter

by Protec Tech Team August 09, 2016

Reduced electrical connections decrease the effectiveness of the ground bed and can cause substantial power quality-related problems and/or catastrophic failure in the event of a major electrical surge.


Test Resistive and Inductive Material with AEMC 6250 Micro-Ohmmeter

by Protec Tech Team July 22, 2016

The AEMC 6250 10A Micro-Ohmmeter is an accurate Micro-Ohmmeters with results up to 0.05% high accuracy, utilizing a four-lead Kelvin method of testing,

With the AEMC 6250 10A Micro-Ohmmeter resistance measurements are automatically calculated and displayed, taking into account the measurement value, ambient temperature, reference temperature and metal temperature coefficient. Sample temperature can be manually entered by the operator or directly measured by the AEMC 6250 10A Micro-Ohmmeter with an external RTD temperature probe.


Megger DLRO200-115 Digital Low Resistance Ohmmeter Operational Specs

by Protec Tech Team April 13, 2016

The Megger DLRO200-115 Digital Low Resistance Ohmmeter is an a.c. powered low resistance ohmmeter designed to measure d.c. resistances in the low milliohms or microhms using a maximum test current of 200 Amps d.c. The maximum test current available is dependent upon the power supply, the resistance of the test leads and the resistance of the item being tested.


AEMC 6250 Micro-Ohmmeter Resistance Analyzer

by Protec Tech Team March 07, 2016

The AEMC 6250 Micro-Ohmmeter is uniquely designed to conduct tests on both resistive and inductive material, with operator selection directly from the front panel. Three test modes are available: resistive (instantaneous test), inductive (continuous test), and auto (repetitive test). Up to 1500 measurements can be stored and printed directly to a printer or from a PC.
