Page 15: Trimming The Transmitter
Quick Start Guide January 2025 5 Trimming the transmitter The factory calibrates the transmitters. Once installed, Emerson recommends performing a zero trim on gauge and differential pressure transmitters to eliminate error due to mounting position or static pressure effects. You can perform a zero trim either a Field Communicator or configuration buttons. - Page 16 (no O-ring visible). Figure 5-1: Digital Zero button A. Digital Zero button Note You can also use AMS Wireless Configurator to perform a zero trim once the device has joined the network. www.Emerson.com...

Page 17: Verifying Transmitter Configuration
You can verify configuration in four locations: • At the device via the local display (LCD display) • By using the Field Communicator • Via the Emerson Wireless Gateway’s integrated web interface • Via AMS Wireless Configurator 6.1 Verifying transmitter configuration using LCD display The LCD display will show the output values at the same rate as the wireless update rate. - Page 18 Status. This page will show whether the device has joined the network and if it is communicating properly. Note It may take several minutes for the device to join the network. See the Emerson Wireless 1420 Gateway Quick Start Guide for more information. www.Emerson.com...
