Measuring the accuracy of electric meters (electronic and mechanical) (MI 2892/MI 2885)
PC Software PowerView v3.0 is an integral part of a measuring system which provides easiest
way to download, view and analyse measured data or print reports.
o
PowerView v3.0 analyser exposes a simple but powerful interface for downloading
instrument data and getting quick, intuitive and descriptive analysis. Interface has been
organized to allow quick selection of data using a Windows Explorer-like tree view.
o
User can easily download recorded data, and organize it into multiple sites with many
sub-sites or locations.
o
Generate charts, tables and graphs for your power quality data analysing, and create
professional printed reports.
o
Export or copy / paste data to other applications (e.g. spreadsheet) for further analysis.
o
Multiple data records can be displayed and analysed simultaneously.
o
Merge different logging data into one measurement, synchronize data recorded with
different instruments with time offsets, split logging data into multiple measurements,
or extract data of interest.
o
Instrument remote access over internet connection.

Safety considerations
To ensure operator safety while using the MI 2893/MI 2892/MI 2885 instruments and to minimize the
risk of damage to the instrument, please note the following general warnings:
The instrument has been designed to ensure maximum operator safety. Usage in a way
other than specified in this manual may increase the risk of harm to the operator!
Do not use the instrument and/or accessories if any visible damage is noticed!
The instrument contains no user serviceable parts. Only an authorized dealer can carry out
service or adjustment!
All normal safety precautions have to be taken in order to avoid risk of electric shock when
working on electrical installations!
Only use approved accessories which are available from your distributor!
Instrument contains rechargeable NiMH batteries. The batteries should only be replaced
with the same type as defined on the battery placement label or in this manual. Do not use
standard batteries while power supply adapter/charger is connected, otherwise they may
explode!
Hazardous voltages exist inside the instrument. Disconnect all test leads, remove the power
supply cable and switch off the instrument before removing battery compartment cover.
Maximum nominal voltage between any phase and neutral input is 1000 V
RMS
. Maximum
nominal voltage between phases is 1730 V
RMS
.
Always short unused voltage inputs (L1, L2, L3, GND) with neutral (N) input to prevent
measurement errors and false event triggering due to noise coupling.
