DIAGNOSTICS
DC voltage measurement
(HART terminals)
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 ma
in 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.
DISCONNECTING FROM A
HART DEVICE
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.
