(25.000) or goes below -15000 (-15.000).
2 point Linearization: In this mode the display will relate indirectly to the electrical
input. This case is typically used to create a process meter.
Using the example of a 20V DC meter, a 1 to 10VDC process output will be
monitored and will display the result in percent. 1 Volt represents 0% and 10 Volt
represents 100%. Notice that on 2 point linearization no symmetry is assumed.
The display will show over-range (EEE or -EEE) when the display exceeds 10000,
(100.00), (input above 10V even though the card is designed to handle up to 20V)
or goes below 0(0.00).
Multi-point Linearization: In this mode the display will not relate to the electrical
input. This case is typically used to flatten a logarithmic response. This feature is
only included on the 4-1/2 digit unit. Up to 16 points of data can be entered.
Using the example of a 20V DC meter, we wish to monitor a -5 to 20V DC pressure
transducer that spans 0 psi to 300 psi but in a non linear way.
The transducer manufacturer provides the following information:
-5 Volts = 0 Psi
0 Volts =10Psi
5 Volts = 40Psi
15 Volts = 80Psi
18 Volts =200Psi
20 Volts =300Psi
We will use this data to develop 6 point linearization.
Notice that on Multi-point linearization no symmetry is assumed. The display will
