Resistance testers for electrical equipment and connections

A micro-ohmmeter measures the resistance of a joint, connector, busbar, cable or connection using Ohm’s law, where a DC is passed through the item under test, and the voltage drop across the circuit or connection is measured. Basic micro-ohmmeters are suitable for measuring the resistance of simple equipment such as joints, welds and cables. However, more complex equipment such as transformers and motors require more specialised equipment with features such as inductive load testing capabilities to test the equipment safely.

What is a micro-ohmmeter?

A micro-ohmmeter, often referred to as a ductor tester, gauges the resistance of electrical circuits or connections. It applies Ohm’s law by sending a DC through the test item and measuring the voltage drop. While basic models assess simple equipment like joints and cables, advanced ones with inductive load testing are needed for complex objects like transformers and motors.

What are the different types of micro-ohmmeters I can rent from Brandis Hire?

At Brandis Hire, we offer micro-ohmmeters from well-known brands, including:

  • AEMC — Known for its precision, versatility and features like data storage and automatic temperature compensation.
  • DV Power — A leader in electrical wire testing equipment with over 15 years of expertise, ensuring accuracy and reliability.
  • Megger — High-performance micro-ohmmeters perfect for assessing contact resistance in various applications.
  • Omicron CPC100 — A user-friendly choice favoured by utilities and railway systems for its accuracy.
  • Sonel — Ideal for low-resistance measurements, especially in junctions and transformers.

What are the applications of a micro-ohmmeter?

Micro-ohmmeters are primarily used for measuring very low resistances with high precision. Typical applications include testing electrical joints, bonding, connectors, busbars, cables, welds and larger equipment like transformers and motors. They’re also used in quality control for manufacturing processes and maintenance checks for aerospace, electronics and power distribution industries.

What is the measuring range of a typical micro-ohmmeter?

A typical micro-ohmmeter can measure resistances from several micro-ohms (µΩ) up to several ohms, depending on the model and specifications. The exact range varies by device, but they are designed to capture extremely low-resistance values accurately.

How accurate are micro-ohmmeter measurements?

Micro-ohmmeters are designed for high precision and accuracy. Many models can measure resistances with accuracies of 0.1% or better. However, the exact accuracy depends on the specific model, the quality of the device and the conditions under which measurements are taken.

What safety precautions should I take while using a micro-ohmmeter?

Always ensure the device is in good working condition before use, and avoid measuring on live circuits. Ensure the equipment under test is de-energised and isolated. Use appropriate personal protective equipment, and always refer to the manufacturer’s safety guidelines provided in the user manual.

Can a micro-ohmmeter measure the resistance of live circuits?

No, micro-ohmmeters should not be used on live circuits. Before taking measurements, ensure the circuit is de-energised and isolated to prevent any risk of electric shock or damage to the instrument.

What are the advantages of using a micro-ohmmeter over a standard ohmmeter?

Micro-ohmmeters are designed to measure extremely low resistances with high precision. They often employ a four-wire measurement technique to eliminate lead resistance errors. Standard ohmmeters might not have the sensitivity or precision to capture such low-resistance values.

How long does it typically take to get a stable reading with a micro-ohmmeter?

The time to get a stable reading can vary based on the device and the resistance being measured. However, many modern micro-ohmmeters provide stable readings within seconds. For very low resistances or when using high precision modes, it might take a bit longer.

How do temperature variations affect micro-ohmmeter measurements?

Temperature can influence resistance values. Many metals, for instance, see their resistance increase with rising temperatures. Some micro-ohmmeters come with automatic temperature compensation features to account for this. However, for the most accurate readings, it’s advisable to measure at a consistent, known temperature or use correction factors.

Is it possible to perform automated testing with a micro-ohmmeter?

Yes, many advanced micro-ohmmeters come with features that allow for automated testing. This can include programmable sequences, data storage and even connectivity options to interface with computers or other devices for data logging and analysis.
