Applications
The calibrated energy meter can be used to acquire and bill active
energy in industrial, household, commercial and building manage-
ment applications. Relevant values are transmitted to data log-
ging, billing and optimizing systems, as well as to building auto-
mation and control technology applications, by means of a pulse
output or via a bus interface. Installation itself is extremely simple
because the meter detects connection errors, which are indicated
immediately. Maximum convenience is assured by displaying
active power, which provides immediate information regarding
momentary circuit load. If you wish to have more ample informa-
tion about mains parameters, you have the option of adjusting the
functions flexibly to your measuring task.
Applicable Regulations and Standards
Multifunctional Variant
Depending on the type of multifunctional variant, the meter is also
capable of acquiring reactive power and indicating up to 33 addi-
tional measured quantities directly on the display.
As a result, voltage level, utilization of individual phases, reactive
power component and the functioning of compensation systems
can be evaluated at any time by simply pressing a button without
any additional measuring equipment. Refer to the table below for
details.

Total power (kW/kVAr) appears in auxiliary display 2 with sign.
2
Not approved for billing purposes in Switzerland
3
The greatest current value per phase is used as a reference value for accuracy.
