Configuration & Calibration
25
A. Begin configuration by using Tag ID (8 characters) to
identify the unit or vessel. Use the Scratchpad (32
characters) to record the date of calibration or other
similar notes. Press Tab or Enter on your keyboard.
B. Select Level or Vessel in the Analog Loop Assign
selection box. Press Tab or Enter on your keyboard.
• Level configuration sets the output to follow the level of
the material being measured.
• Vessel configuration sets the output to follow the
strapped volume in the vessel. For example, gallons in
a horizontal vessel.
Note: Changing between Level and Volume will
automatically change the LRV value to 0 and the
URV to the maximum level or maximum capacity as
appropriate.
C. Edit Damping Time from 0-90 seconds, if desired.
D. Click on Write to Transmitter.
E. Move to Level Configuration section of menu.
3.4.1 Level Configuration
A. Select Level Units. The default is feet. Choose the units
that correspond to the level measurement.
Note: Changing Level Units will automatically convert
unedited entries for maximum level, LRV, URV, lower
level and upper level to the new units when the change
is written to the transmitter. For example: Changing
from feet to inches will automatically multiply all
entries by 12 unless they have been manually edited.
B. Edit the Maximum Level to agree with the sensing
element length or the actual tank height if referencing
vessel dimensions for output. For an accurate volume
conversion the maximum level must equal the tank
height.
C. Click on Write to Transmitter and move to the
Vessel Configuration section of the menu.
