Emerson Transmitter LTM-300- Manuals

Level/Interface. A second float may be added below the first one, and the second output will be calibrated automatically. The second time interval is measured in the same manner as the first and added to the first to derive the position of the heavier float. The same six inch dead zone applies to the mea...

If the transmitter is configured as Level Only or Level plus Temperature, the screen to the left shows the information displayed to the user. However if the tran...

Starting at the Calibration screen, select the Zero Level Trim procedure. This procedure trims the Level digital value measurement at the position that the user desires to be the zero reference position. If the user selects Zero Level Trim from the Calibration screen, this screen will appear remindi...

The HART Communicator now requests that the level float be set to the desired level upper trim point. The second trim point can be any other level point but it is recommended that this point be as far away from the zero point as possible. When the float is at this position, the transmitter will always...

The user is then notified that the loop may now be returned to automatic control. After the user presses OK the HART Communicator returns to the Calibration screen. The HART Communicator is now at the starting screen for the Zero Temper Trim . Full Temperature Trim Starting at the Calibration screen,...

The next screen gives the user a choice to set the 4mA or 20mA values or to Exit the procedure. Here the user will select the 4mA menu position. The HART Communicator requests the user to set the Level (or Interface) to the position that is to provide the 4mA loop current output. When that has been ...

If the user selects Revision #’s from the Device information screen, the screen to the left will display the revisions of the transmitter.
