IMPORTANT
Communication signal is superimposed on
analog output signal. It is recommended to set
alow-passlter(approximately0.1s)tothe
receiver in order to reduce the output effect
from communication signal. Before online-
communication,conrmthatcommunication
signal does not give effect on the upper system.
IMPORTANT
Restrictions exist with regard to the distance
over which communication is possible. When
simultaneous output of current and pulse output
or pulse output are used, no communication is
possible depending on the wiring. Read Section
4.6 and Chapter 12 in detail.
IMPORTANT
Ifthepowerofowmeteristurnedoffwithin30
seconds after parameters have been set, these
settings will be canceled. Accordingly, please
keep the power on for at least 30 seconds after
setting parameters.
IMPORTANT
After approximately 5 minutes of inactivity, the
Auto Power-Off function will operate to turn your
BT200 off.
WARNING
Be sure to set parameters as “Protect” on the
writeprotectfunctionafternishofparameter
setting work.
Read Chapter 6 Menu P and Subsection 11.3.2,
how to use the write protect function in detail.
NOTE
In case of BT200, the parameters are displayed
in English only.
Even if the language with the exception of
English is selected at B10/H30:Language,
the parameters are displayed in English upon
BT200.
