Design and function,

Max. Values
The calculator creates max. values for power and
flow rate based on consumption time, which are
stored in the EEPROM. The integration intervals
are adjustable to 6, 15, 30 or 60 minutes and 24 h.
Default setting is 60 minutes.
Tariff Function
The calculator offers two optional tariff
memories for monitoring plant load states for
limit tariffs. Here it concerns threshold value
tariffs. Extensive tariff conditions make it possible
to adapt the calculator individually to the
required customer-specific applications.
Both tariffs are separately configurable and
independent from each other. Energy or time
can be measured alternatively per tariff register
dependent on the tariff mode adjusted in each
case.
With the “time triggered tariff function” (type Z)
the switch-on time and the switch-off time are
adjustable independent from each other for each
day of the week in steps of 15 minutes.
The following limit types are possible:

Display Control
The readings are displayed on the calculator by a
7-digit LCD with units and symbols.
Loop Structure
The INFOCAL 6 display has six loops. Some
display windows consist of two (to maximum
seven) displays that are shown alternately at
4-second intervals. Some pictures in loops or a
complete loop can be deactivated separately.
For quick visual guidance, the loops in the
display are numbered from 1 to 6.
The main loop with the current data, e.g. for
energy, volume and flow rate, is programmed as
default setting.
In the standard setting the loop no. 5 (tariff loop)
is not activated.
