Linearization Menu - K-TEK MT5000 Installation & Operation Manua

4.6.4. LINEARIZATION MENU

The LINEARIZATION function of the MT5000 is a multi-purpose tool designed to enhance the operating capabilities
of the MT5000 transmitter. The format of the LINEARIZATION TABLE allows a set of values to be assigned to
measured level points along the PROBE LENGTH. The points in the table can be assigned exact measured values
to linearize the measured level for increased accuracy at the top and bottom of the probe, assigned volume points
for tank strapping, or assigned flow rates for measurement of flow in an open channel.
LINEARIZATION MENU items:
1. LIN UNITS
Allows the selection of the desired output UNITS based on the values of the lin-
earization table. LIN UNITS include measurement selections such as meters,
volume selections such as gallons, and flow selections such as liters/hour.
(Table 2)
2. LIN MINIMUM
The value assigned to the lowest measurable point along the PROBE LENGTH.
Typically this will be set to 0, although it is not required.
3. LIN MAXIMUM
The value assigned to the highest measurable point along the PROBE
LENGTH. This value will be greater than the largest point in the Linearization
Table.
4. LIN MODE
This will determine how the values in the table will be assigned. Manual Mode
allows the entry of the values along with the respective measured level. Auto-
matic requires the level of the product to be at the measured level when the re-
spective value is set.
5. LINEARIZATION TABLE
The set of parameters used to collate Measured Level and a user selected set
of values for those Measured Levels. Table points will be entered based on the
LIN MODE. Table points must be entered from smallest value to largest value
from point 01 to point 20. In Manual Mode, the table will ask for Output Point 01
-20 then ask for the corresponding Input Point 01-20. The Output Point is the
desired reading. The Input Point is the Measured Level. In Automatic Mode, the
table will only ask for the Output Point 01-20. The corresponding Input Point will
be gained by setting the level to the correct location along the PROBE LENGTH.
Changing the UNITS in the BASIC SETUP menu will automatically change the UNITS of the Input Points. Changing
the LIN MAXIMUM after table points are set will cause the table points to change based on the percentage change
of the LIN MAXIMUM.
