DISCONNECTING FROM A
HART DEVICE
The HART DC voltage measurement takes a voltage reading at the HART connector
and displays it in the window.
To check the device voltage:
1. From the HART Application main menu, double-tap HART Diagnostics.
2. Double-tap DC Voltage Measurement. The DC voltage measurement appears.
3. Tap OK when you are finished viewing the measurement. To refresh the window,
double-tap DC Voltage Measurement from the HART Diagnostics menu.
CAUTION
Voltage measurements are for reference purposes only. Do not make critical process
control decisions based upon these measurements.
Prior to disconnecting the 475 Field Communicator from a HART device, check the
following items:
• Determine if you want to save a configuration.
• Verify methods, such as calibration or loop test, are complete.
• Resolve any un-sent data to the device.
