Zero and Span Adjustment Requirements

Zero and span values can be set anywhere within the range limits stated in Table A-1.

Span must be greater than or equal to the minimum span stated in Table A-1.

A.3 Wireless Self-Organizing Networks

Output

IEC 62591 (WirelessHART) 2.4 GHz DSSS

Wireless Radio (Internal Antenna, WP Option)

Frequency: 2.4 - 2.4835 GHz

Channels: 15

Modulation: IEEE 802.15.4 compliant DSSS

Transmission: Maximum of 10 dBm EIRP

Local Display

The optional 3-line, 7-digit LCD can display user-selectable information such as primary variable in engineering units, scaled variable, percent of range, sensor module temperature, and electronics temperature. The display updates based on the wireless update rate.

Digital Zero trim

Digital Zero trim (option DZ) is an offset adjustment to compensate for mounting position effects, up to 5% of URL.
