Understanding Micro and Milli Ohmmeters for Testing

Low resistance testing plays a big role in electrical maintenance and quality checks. Even small changes in resistance can point to loose joints, worn contacts, or damaged cables. Meco Instruments offers the Micro-Ohmmeter (Model 7272) and Milli-Ohmmeter (Model 7002) for this exact purpose. These instruments are built for accuracy, reliability, and ease of use in the field or lab.

High Accuracy and Wide Measurement Range

Both models offer a basic accuracy of 0.25%. This level of precision is important when testing critical joints and connections. The instruments come with 6 ranges and a best resolution of 1µΩ. Model 7002 supports a maximum test current of 5A, while Model 7272 goes up to 10A. This wide range makes them suitable for many different testing needs.

Four Terminal Kelvin Measurement for Reliable Results

These ohmmeters use four terminal Kelvin measurement. This method removes errors caused by lead and contact resistance. As a result, users get clean and dependable readings every time. The instruments can measure both resistive and inductive materials with equal accuracy. This makes them useful across different types of electrical equipment.

Smart Features for Everyday Use

The Micro-Ohmmeter and Milli-Ohmmeter come packed with helpful features. Users can choose manual or auto range based on their testing needs. The device stores up to 3000 measurement readings for later review. It also offers programmable HI-LO alarms with memory for 20 data points. A large LCD with backlight and hold function makes readings easy to view. Clear HI, LO, and PASS indications help users make quick decisions on site.

Practical Design for Field and Lab Work

These instruments are designed with real-world use in mind. They run on a rechargeable battery and show a low battery warning when needed. A built-in calendar clock and battery charging circuit add extra convenience. Cable length can be measured in both feet and meters. An LED indication also alerts users to invalid resistance readings. The set includes Kelvin clips, an AC adaptor, and a carrying bag for safe transport.

Easy Data Management with PC Software

Data handling is simple with these instruments. They come with user interface software for PC communication. This works through an RS232C to USB bridge cable. Users can transfer, view, and store test data with ease. This feature is useful for teams that need proper record keeping and analysis.
