Description |
|
The MI 2092 is a three-phase, multifunctional,
portable power harmonics analyzer with six differential channels.
This useful tool has the ability to measure, record, and analyze
power distribution systems – including functions for power
quality, measuring energy, and harmonics. The test set also
comes with Power Link; a comprehensive, easy-to-use software
program that makes it a snap to download, store, and analyze
test information.
