APPLICATION
Please read this important information!
Intended Use/Use for Intended Purpose
The MAVOWATT 2XX series by GOSSEN METRAWATT comprises models
MAVOWATT 270, MAVOWATT 270-400, MAVOWATT 240 and MAVOWATT 230.
They are portable, hand-held, eight-channel power quality meter/monitors which are
very similar in operation, although the MAVOWATT 270 also has a high speed
sampling board for capturing the details of very fast transients. The features common
to all monitors are covered in this document, and the MAVOWATT 270 name will be
used to represent all four instruments. These cutting-edge power quality instruments
are designed with a 7” WVGA wide screen LCD, using touch screen technology.
They can monitor, record and display data on four voltage channels, as well as four
current channels simultaneously.
The MAVOWATT 270 is designed to meet both the IEEE 1159 and IEC 61000-4-30
Class A standards for accuracy and measurement requirements. It can do PQ-
optimized acquisition of power quality related disturbances and events. It is designed
with a statistical package called Quality of Supply (QOS), with monitoring and setup
protocols set to determine voltage measurement compliance required for EN 50160
monitoring. European standard EN 50160 requires that measurement parameters
must be within a specified percentage for 95% of the time.
The MAVOWATT 270 also allows you to perform automatic setup or to customize
threshold settings for power quality or energy/demand. The power quality and
energy/demand dashboard interface helps you monitor and manage energy
consumption including utility costs.
The MAVOWATT 270 firmware can monitor power quality and energy/demand
phenomena for troubleshooting and/or compliance purposes. It can record inrush
conditions, carry out long-term statistical studies to establish performance baselines,
and perform field-based equipment testing and evaluation for commissioning and
maintenance. The firmware integrates an intuitive instrument setup procedure to
ensure the capture of all relevant data for additional post process analysis, report
writing, and data archiving using other compatible GOSSEN METRAWATT software
applications such as Dran-View®.
.
Use for Other than Intended Purpose
Using the instrument for any purposes other than those described in these
condensed operating instructions, or in the instrument’s operating instructions, is
contrary to use for intended purpose.

INSTALLATION AND CONFIGURATION
NOTICE
•Charge Battery Before Use!
Always charge the battery fully before using the instrument! The instrument
will fully charge its internal battery in three (3) hours.
The instrument will always operate on the charger and is designed to do so
regardless of the state of charge of the battery.
Refer to the User Guide for additional information.
•Set Time and Date
From the Home screen, press the Setup Instrument ( ) icon, then press Set
Time and Date.
Set the time zone applicable to your application using the Time Zone drop down
selection list.
NOTE: Time and/or date cannot be changed if monitoring is on.
The MAVOWATT 270 also lets you synchronize time, so that all of your devices
are using the same time for data recording. Time sync options include GPS, NTP
or Real Time Clock (RTC). Each Time Sync Source button toggles the respective
source enabled or disabled.
If all three are enabled, time sync is sourced by the instrument in the following
priority order: If GPS is available, then it is used. If not and NTP is available, then
NTP is used. If neither GPS nor NTP is available, then RTC is used.
NOTE: If the battery is removed and only RTC time is available, the instrument
reverts to the default time/date.
Refer to the operating instructions for further information, which can be found at
http://www.gossenmetrawatt.com. Retain the document for future reference.

Measurement Cable with Optional Fused Voltage Adapter
WARNING
To avoid the risk of electric shock or burns, always connect the safety (or earth)
ground before making any other connections.
WARNING
To reduce the risk of fire, electrical shock, or physical injury, it is strongly
recommended to fuse the voltage measurement inputs. Fuses must be located as
close to the load as possible to maximize protection.
WARNING
For continued protection against risk of fire or shock hazard, replace only with same
type and rating of recommended fuse.
WARNING
Do not replace fuse again if failure is repeated. Repeated failure indicates a defective
condition that will not clear with replacement of the fuse. Refer condition to a qualified
technician.
