Emerson.com/Global. Shipping considerations for wireless products: Emerson shipped the transmitter to you without the power module installed. Remove the power module prior to shipping the transmitter. Each power module contains one D size primary lithium-thionyl chloride battery. Primary...
Power up sequence Do not install the power module on any wireless device until the Emerson Wireless Gateway is installed and functioning properly. This transmitter uses the green power module (order model number 701PGNKF). Power up wireless devices in order of proximity from the Gateway, beginning with the closest.
2. Mount the transmitter beside or below the taps. Mount the transmitter so the drain/vent valves are oriented upward. 2.2 Mount the transmitter in gas applications Procedure 1. Place taps on the top or side of the line. 2. Mount the transmitter beside or above the taps. www.Emerson.com...

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.

(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...
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.
