1. Compact micro-ohmmeter MIKO-10 is designed for easy measurement of the DC electrical resistance using a current of 1 A / 10 A.
Applications include:
– contacts of high-voltage circuit breakers (including with built-in current transformers);
– connecting or disconnecting switches, busbars, wires and cables;
– bolted, riveted, welded and brazed joints, aircraft skins, etc.
2. The instrument has 3 start modes for the measurement process:
- AUTO: is designed to measure the contact resistance of high voltage circuit breakers without current transformers and any demountable or non-demountable connections with current of 10 A. The measurement starts automatically when the test cables are connected;
- SINGLE: is designed to measure the contact resistance of high-voltage circuit breakers without current transformers and any demountable or non-demountable connections with current of 1 or 10 A.
· BUILT-IN CT: is designed to measure the contact resistance of high-voltage circuit breakers with built-in current transformers.
3. The instrument has a number of important additional functions that meet the latest user requirements:
– Auto thermal EMF balancing in the test circuit;
– Auto power off, if the instrument is not used;
– Circuit continuity test;
– Auto measurement start against the test circuit continuity confirmation;
– Sounds an alarm at the start and at the end of the measurement.
4. MIKO-10 can justly be referred to portable instruments due to its light weight of only 0.5 kg and small dimensions 165 × 100 × 60 mm.
