Normally, it is an electrical instrument that measures small resistances with high precision. In other words, it could be defined as a microcontroller-based instrument, which is available in various designs. It has a high level of precision and is ideal for use in laboratories, universities and any other manufacturing unit. Unique features of the micro ohmmeter include: a fully automatic range adjustment and hold function, which are very easy to operate. In fact, all the operations of this instrument could be done manually.

Important features of this instrument:

• This resistance meter has a special compare function, a comparator with good and bad output values. In this way, faulty components could be removed separately.
• This resistance meter has other additional functions such as mains loss protection, battery backup, password protection and speakers.
• Its large display is very bright and clear and provides a wide viewing angle that acts as a perfect laboratory measurement tool or as a resistance meter in an automatic test system.
• The readings displayed by this measurement resistor are very fast to read on interfaces. Its simple set of instructions makes it easy to integrate with existing measurement technology.
• These instruments are available from 1 A to 200 A. The special protection setting protects against voltages, for example, from charged devices being tested. You will likely choose to control the measurement tool itself via an external, internal, or fuzzy trigger. It has measurement software, and its features include fast data acquisition and saving.
• Overall it has a very low measurement device with 4-wire Kelvin probe procedures and powerful resolution as well as a high measurement current to measure the smallest resistances.
• A resistance tester of this design is well suited for laboratory use, for the automotive industry, for testing the quality of mechanical connections and contacts, for aircraft construction, in automatic test systems, and for all other purposes where measurement of small resistance value is required.
• Other applications include: It is very useful in the electrical and electronic industry. It could be used to find the resistance of transformer or motor winding.

This precision instrument is extremely suitable for measuring low value resistors. It uses state-of-the-art technology for the measurement of low resistance values. The technique used by him is useful for eliminating errors caused by resistance in connection cables. The instrument uses precision low-drift integrated circuits to ensure measurement stability under widely changing conditions. Micro ohmmeters are available from different brands, all of which are very accurate, affordable, and are available with auto-ranging capabilities. Various accessories are also available that will enable accurate and efficient measurements of very low resistance values.
