Searchpoint Optima Plus can communicate with the SHC1 Handheld Interrogator, which can be used to
access comprehensive diagnostic information, and to carry out calibration and configuration. As an option,
HART communications are available to perform the same functions either using a HART
®
or from a central control room.
Note: Searchpoint Optima Plus can be installed, commissioned and functionally tested using only the
4-20 mA output. However, configuration, calibration and fault diagnosis require either the SHC1 Handheld
Interrogator, HART communications or the XNX Universal Transmitter.
