Step
20 When the display in Step 18 appears, choose Exit, then press ENTER.
Return the loop to automatic control.
21 Press HOME to return to the "Online" display.
22 From "Online" menu, step through the following menu selections:
Device setup
•
• Process variables
23 At "Process variables" display, read 100% output for corresponding full tank pressure applied.
Check that milliammeter reading is 20 mA (100%) output.
24 Take communicator and milliammeter readings to check that output signal does correspond to
empty and full tank pressures.
If readings do not correspond, check that transmitter has been installed correctly. If applicable,
blow down piping to be sure no foreign matter is entrapped in it.
Check communicator and milliammeter readings again. If readings are still not correct, verify
transmitter's configuration data and change its range setting, if needed.
Ranging the transmitter in this way makes it reverse acting.
25 Remove communicator and milliammeter from loop.

Pressure or Liquid Level Measurement with GP Transmitter

Procedure
The procedure in Table 33 outlines the steps for starting up a gauge pressure (GP) type transmitter in a
pressure or liquid level measurement application. Refer to Figure 32 and Figure 33 for the piping
arrangement identification and Figure 27 for typical communicator and meter connections..
