Fct 1.00
Level
(LEVEL)
You must start with this level menu to configure and calibrate
the Univesal IV device. 'Level' is defined as the distance
from the tank bottom to the level of the material. Two
calibration points are required to configure the unit. 'Point
Cal' requires an actual level to be present in the vessel.
'Calculated Level' is a predetermined calculated value that is
independent of the level in the vessel. The user can mix and
match 'Point Cal' and 'Calculated' (i.e. two 'Point Cal', two
'Calculated level', 'High Point Cal' and 'Low Calculated Level'
or vice versa)
Fct 1.01
Units
(UNITS)
Feet (FEET) - default Setup level units in feet
Inches (INCHES) Setup level units in inches
millimeters (MM) Setup level units in millimeters
centimeters (CM) Setup level units in centimeters
Meters (METERS) Setup level units in meters
Fct 1.02
Tank height
(TANK HT)
200 feet (DEFAULT) Enter the tank height from the bottom to the top of the tank in
level units selected above. This entry is required for volume
conversions only.
Greater than 0 Example: For a 20 foot tall tank '20' will be entered if 'Feet'
was selected as the level unit above or "240" will be entered
if "Inches" was selected
Fct 1.03
Low Point Cal
(PCAL LO)
0 feet (DEFAULT) Enter your current low level value in your vessel. You
must know the actual level before performing a 'Point Cal'
calibration. Entering a value above the "High Point Cal" will
invert the output.
0..No upper limit In level units selected above
Fct 1.04
High Point Cal
(PCAL HI)
100 feet (DEFAULT) Enter your current high level value in your vessel. You
must know the actual level before performing a 'Point Cal'
calibration. Entering a value below the "Low Point Cal" will
invert the output.
0..No upper limit In level units selected above. 'High Point Cal' and 'Low Point
Cal' must be at least 10% apart.
Fct 1.05
Low Calibration Level
(LOW LVL)
0 feet (DEFAULT) Display actual value from Fct 1.03 or edit to change to a
calculated value. The level in the vessel does not have to
change if you are entering a calculated value. This step is
typically done in conjuntion with Fct 1.06
0..No upper limit Enter the desired level in units selected above. This entry
is read only unless you are performing a calculated level
calibration
Fct 1.06
Low Calibration
Capacitance
(LOW CAP)
pF (DEFAULT) Read the capacitance in pF for the low calibration level
associated with Fct 1.05 and 1.03. Edit to change to a
known or calculated value for the 'low calibration level' in Fct
1.05. Contact Drexelbrook Service department for values if
required.
"0..45,000 (on Pro models)
0..7,000 (on Lite models)"
Capacitance value in pF. This entry is read only unless you
are performing a calculated level calibration
Fct 1.07
High Calibration Level
(UPR LVL)
100 feet (DEFAULT) Display actual value from Fct 1.04 or edit to change the
current stored value. The level in the vessel does not have
to change if you are entering a calculated value. This step is
typically done in conjuntion with Fct 1.08
0..No upper limit Enter the desired level in units selected above. This entry
is read only unless you are performing a calculated level
calibration
