Mode of Operation

Input voltages and currents are sampled for calculation of
the corresponding RMS values. All measurements derived
from sampled values are calculated by a processor. Meas-
ured quantities can be displayed on the screens and/or
transmitted via the serial interface.
With the SIMEAS P, it is possible to program limit value
groups for various measured quantities to activate limit
violations when the value of a specific measured quantity
exceeds a programmed threshold. In addition, it is possible
use logical elements (AND, OR) to combine two or more
measured quantities for the purpose of generating a limit
violation. Limit violations are counted, indicated on the
screen and/or utilized to operate the binary output contacts.
The oscilloscope may be triggered via a limit violation as
well. All measured quantities can be displayed on the
SIMEAS P screens as required by the user. Up to 20
screens can be selected with the front keys. The number,
type, content and sequence of the screens are configurable.
SIMEAS P is delivered with pre-programmed default set-
tings.
A status line displayed in the measured value screens indi-
cates status, interfacing and diagnostic messages for the
SIMEAS P.
The display is automatically refreshed every second.
