summaryexistMO-5889-200AA high current micro ohmmeter is a portable, microprocessor controlled instrument. Optimized filters and protection devices can be used for measurement in substations. Can be used for up totwo hundred4ATest the current accurately and measure the extremely low contact resistance of high-voltage circuit breakers, switches, busbars, etc. It adoptsTerminal method（

U / IMeasurement principle) to avoid errors in passing through the test line and its contact resistance.The advanced signal amplification system ensures measurement accuracy, with no offset and long-term stability. The resistance reading is displayed on the alphanumeric screen, with a maximum resolution of4½Position. It allows measurement up to20mΩThe optimal resolution for the resistance is

0.1μΩ200.The operator can adjust the test current and measure its value using a simulated indicator (bar graph). It has an internal memory that can store up toA reading.

USBThe interface can be connected to a computer to download stored values.High current power generation systems based on modern technology can significantly reduce their weight (approximately

twenty-four point two five

lb | 11 kg）And size.The cabinet is made of plastic and has high impact resistance and environmental challenges. The internal thermal sensors in all sensitive components can prevent any damage to the instrument caused by overheating.

This is a sturdy but lightweight device that can be easily carried by one person. It is waterproof and can be used in harsh weather conditions（
