The above EMC tests have been carried out with the flowmeter installed properly in accordance with
this instruction manual. However, there is no guarantee that interference will not occur in a particular
installation.
To reduce interference to or from other equipment, please check the following installation points.
(1) Use shielded cables for all I/O cables. When the flowmeter is the separated type, the signal cable
and excitation cable for the connection between the detector and the converter are supplied by
Toshiba. To improve immunity, pass each cable through a thick steel conduit tube.
(2) If this device is installed in an area where RFI exists, deviation of the current output signal may
be caused. In this case, ferrite cores will be required on each I/O cable. Please contact Toshiba or
the agency if required.
(3) This device is designed to be used in an industrial environment and may cause reception
interference to radio, television or wireless communications. In this case, relocate the receiving
antenna.
(4) The use of a transceiver or wireless equipment near this device may cause interference to the
accurate measurement. If deviation of the output signal appears during use of a radio, increase
the distance between the converter or the signal cable and the antenna.
