The MO-5898-200A high current micro-ohmmeter employs the 4 terminals-method to avoid measurement errors caused by test leads and their contact resistances. Resistances readings are shown in the alphanumeric display with up to 4½ digits-resolution. It allows to measure resistances up to 200 Ω, with a resolution of up to 0.1 µΩ.
Using its internal rechargeable battery, measurements with up to 10 A test current may be carried out without connecting the equipment to mains power. Powered by to mains power, it allows to measure with any test current up to 200 A.
Measurement accuracy is guaranteed by an state-of-the-arts signals amplification system, offset-free and of high long-term stability.
Test current may be adjusted by the operator in every one of the scales and their values are measured using an analogue indicator (bargraph), making it easy to measure resistances with a significant inductive component, as in the case of big transformers windings.
The high-current generation system is based on modern technology that allows to significantly decrease both its weight (16 kg) and size. The cabinet is made of plastic material highly resistant to impacts and to environmental challenges.
Internal thermal sensors in all sensitive components avoid any damaged caused to the instrument due to overheating.
This is a strong but lightweight equipment, and may be easily carried by one person. It is water-resistant and can be used under severe weather conditions offering an excellent performance working both in the laboratory and out in the field.
