P48: - - - -
Number of linearization data pairs
FACTORY DEFAULT: L( i ) = 0 r( i ) = 0
The data pairs defining the characteristic points must be entered into a table of three columns. The table can be filled with pre-calculated data or
data measured while filling the tank. Column L shows the measured level (LEV) values. Column
“r”
shows the output values assigned to the
measured level (as per
P01 (a)
).

Conditions of correct programming of the data pairs
The table must always start with: L(1)= 0 and r(1)= value (assigned to 0 level)
Column L cannot contain the same values.
If the table contains less than 32 data pairs, the row after the last valuable data pair in column L must be 0.
If the above conditions are not met and P47 = 1 (table active), an error code will be displayed (see chapter: Error Codes).
Note:
for further information about programming in reference to linearization see user’s manual of the EView software and MultiCONT process controller
5.4.7.
Informational parameters
P60: - - - - Overall operating hours of the unit [h]
P61: - - - - Time elapsed since last switch-on [h]
P62: - - - - Operating hours of the relay [h]
P63: - - - - Number of switching cycles of the relay
P64: - - - - Actual temperature of the transducer [°C]
Broken loop of the thermometer will be indicated by Pt Error message that is initiated by a signal sent via HART. In this case the transmitter will
perform temperature correction corresponding to +20 °C (+68 °F).
