Electronics Trim of an 8712D, 8732C, or 8742C
Magnetic Flowmeter Transmitter

The Rosemount 8714D is a high-precision instrument that supplies a 8712D, 8732C, or 
8742C Magnetic Flowmeter Transmitter with a voltage corresponding exactly to 0.00 ft/s, 
3.00 ft/s, 10.00 ft/s, and 30.00 ft/s. The precise 30.00 ft/s voltage signal may be used to 
recalibrate or verify operation of the transmitter. (This same procedure is used by the factory 
to calibrate the transmitter; it is rarely needed by customers.) 

Perform this procedure only if you believe that transmitter is no longer accurate.

IMPORTANT NOTICE

This installation guide provides basic guidelines for the Rosemount

®

 8714D. It does not 

provide instructions for detailed configuration, diagnostics, maintenance, service, 
troubleshooting. The manual and this QIG are also available electronically on 
www.rosemount.com.

WARNING

Explosions could result in death or serious injury:

 

In an Explosion-proof/Flame-proof installation, do not remove the transmitter covers 
when power is applied to the unit. 

Electrical shock can result in death or serious injury

• Avoid contact with the leads and terminals. High voltage that may be present on leads 

can cause electrical shock.
