Instrument setup on remote measurement site
Installation procedure on remote site starts by connecting MI 2893/MI 2892/MI 2885 instrument to the
grid or measurement point. As measurement campaign can last for days or weeks it is necessary to
assure reliable power supply to the instrument. Additionally, fully charged instrument batteries can
provide power to the instrument during interrupts and blackouts for more than 5 hours (from 5 to 7
hours for MI 2892/2885) and more than 3 hours (from 3 – to 5 hours for MI 2893), depends on the
battery capacity and battery state. After instrument installation, connection parameters should be set.
In order to establish remote connection with instrument through PC software PowerView v3.0,
instrument communication parameters should be configured. Figure below shows COMMUNICATION
menu in GENERAL SETUP.
