Operating the Transmitter
8.1 Overview
This chapter describes how to use the transmitter in everyday operation. The following topics and
procedures are discussed:
• Interpreting mA output data – see Section 8.3
• Recording process variables – see Section 8.4
• Viewing process variables – see Section 8.5
• Viewing and acknowledging status alarms – see Section 8.6
• Viewing and controlling the totalizers and inventories – see Section 8.7
Note: All ProLink II procedures provided in this section assume that your computer is already
connected to the transmitter and you have established communication. All ProLink II procedures also
assume that you are complying with all applicable safety requirements. See Appendix D for more
information.
Note: If you are using AMS, the interface is similar to the ProLink II interface described in this
chapter.
Note: All Communicator key sequences in this section assume that you are starting from the “Online”
menu. See Appendix E for more information.
8.2 Warm-up delay
If you have just powered up the flowmeter, the transmitter may not be warmed up sufficiently, and
may exhibit minor instability or inaccuracy. If you observe this, wait approximately ten minutes. If the
condition does not disappear, follow normal troubleshooting procedures.
8.3 Interpreting mA output data
Verify that the host or mA receiving device is interpreting the mA signal correctly: scaled either from
12–20 mA or from 4–20 mA. If the host is receiving a 12–20 mA signal, you may want to configure it
to rescale the input to 4–20 mA. For more information, see Section 3.4.
Note: If you are reading process data from the display, or if you are reading process data remotely
using HART digital communications, the mA output scale does not affect process values.
Be sure to interpret and rescale process data reported via the mA output as appropriate to your
installation. If you do not, you may experience measurement error and unintended consequences for your
process.
