Measurement Display
(Original Document)
Introduction
This process allows you to choose the display format in which measurements are provided to the user application. It's important to differentiate between electrical ranges on the one hand, and thermocouple or thermowell ranges on the other hand.
Standardized Display of electrical ranges
Values are displayed in normalized measuring units (in percent format, with two decimal spaces, also symbolized as °/).
Type of Range
Display
Unipolar range
from 0 to 10000 (0 °/ to +10000 °/)
Bipolar range
from -10000 to 10000 (-10.000 °/ to +10000 °/)
User-specified Display
The user may define the range of values within which measurements are expressed, by selecting:
These lower and upper thresholds are integers between -30000 and +30000.
Example:
Imagine a conditioner providing pressure data on a 4-20 mA loop, with 4 mA corresponding to 3200 mB, and 20 mA corresponding to 9600 mB. You have the option of choosing the User format, by setting the following lower and upper thresholds:
Values transmitted to the program vary between 3200 (= 4 mA) and 9600 (= 20 mA).
Therefore, matches are as follows:
Value transmitted to program
Current
Pressure
3200
4 mA
3200 mB
current value
between 4 and 20 mA
current value
9600
20 mA
9600 mB
Display of Thermal Ranges
Measurements provided to the application are directly usable : you may choose either "In Temperature" Display or Standardized Display:
