Need help? If an error message appears:
• Verify the HART address of the transmitter, or poll HART addresses 1–15.
• Ensure that there is at least 1 VDC across the connection terminals. Add resistance as
necessary to achieve at least 1 volt.
• Ensure that you have specified the correct port on your PC.
• Check the wiring between the PC and the transmitter.
• Ensure that the mA output is powered.
• Increase or decrease resistance.
• Disable burst mode.
• Ensure that the resistor is installed correctly. If the mA output is internally powered
(active), the resistor must be installed in parallel. If the mA output is externally powered
(passive), the resistor must be installed in series.
• Ensure that there is no conflict with another HART master. If any other host (DCS or PLC) is
connected to the mA output, temporarily disconnect the DCS or PLC wiring.
