1.5 Note Concerning Transport
The Lithium-batteries in our equipment are subject to
Special Provision 188 of the UN Recommendations on the
Transport of Dangerous Goods Model Regulations and
Special Provision A45 of the IATA Dangerous Goods
Regulation and the ICAO Technical Instructions.
This is only valid for the original battery or original spare
batteries.
1.6 Range of Application
The SIMEAS P is capable of recording several different
power system measurements. In addition, the SIMEAS P is
designed to be utilized in a number of different industries.
The display of measured quantities can be easily configured
to the specific requirements of the user.
Network linking is possible with the integral RS 485 port
equipped with the standard PROFIBUS DP V1 or Modbus
RTU/ASCII protocol which provide for indication, evaluation
and processing of several SIMEAS P measurements at a
central master station.

8
1.7 Mode of Operation
Input voltages and currents are sampled for calculation of
the corresponding r.m.s. values. All measurements derived
from sampled values are calculated by a processor.
Measured 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, etc.) 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
settings.
A status line displayed in the measured value screens
indicates status, interfacing and diagnostic messages for
the SIMEAS P.
The display is automatically refreshed every second.
