NOTE:
During calibration, the analog output is automati-
cally held at the last measured value and, upon
completion, returned to its active state.
The transmitter is completely safe to handle. Only low DC
voltage is present.
NOTE:
The transmitter can be located in a Class 1, Div. 2
hazardous area.
All user-entered configuration values are retained indefi-
nitely, even if power is lost or turned off. The non-volatile
transmitter memory does not require battery backup.
A label with the transmitter model number, serial number,
and build date is located between the terminal blocks.
The transmitter is designed to provide protection from most
normally encountered electromagnetic interference. This
protection exceeds U.S. standards and meets European
IEC 1000 (EN 61000) series testing for electromagnetic and
radio frequency emissions and immunity. Refer to Figure 1-
1 and the specifications in Section 2.1 for more information.
