Extensions for Customer
Applications: standard or to
order
Mk6E GENIUS plus®meter
continues the successful concept
of meter “Extensions” introduced
in the original Mk6 Genius® Using
“EziScript”, complex register
manipulations can be performed
allowing sophisticated meter
functions. New Extensions are
constantly under development,
contact us to find out the
latest updates.
Some examples of currently available
Extensions are:
• Send SMS at percentage of
maximum demand, or equipment
failure alarm
• Maximum demand control of loads
via pulsing outputs
• Time Of Use history etc
Software
• EziView Windows® software
(optional), can be used for
programming and reading
the meter
• EziView also allows offline
configuration of tariff programs
and all meter parameters, for
later upload
Dimensions
• 262mm (L) 175 mm (W) 93mm (D)
