VALUE 20 mA
(4003)
Use this function to assign the 20 mA current a value. The value can be higher or lower
than the value assigned to 0/4 mA (function VALUE 0_4 mA (4002), see Page 59).
Positive and negative values are permissible, depending on the measured variable in
question (e.g. volume flow).
Example:
4 mA assigned value = –250 l/h
20 mA assigned value = +750 l/h
Calculated current value = 8 mA (at zero flow)
Note that values with different signs cannot be entered for 0/4 mA (function 4002) and
20 mA, if SYMMETRY is the setting selected in the function MEASURING MODE
(4004). In this case, the message "INPUT RANGE EXCEEDED" appears.
Example for STANDARD measuring mode
User input:
5-digit floating-point number, with sign
Factory setting:
Depends on nominal diameter and country (see Page 153 ff.).
!
Note!
• The appropriate unit is taken from the function UNIT VOLUME FLOW (0402) or
UNIT MASS FLOW (0400).
• When conductivity is selected the value 20 mA must be equal or >0.

Caution!
It is very important to read and comply with the information in the function
VALUE 0_4 mA (under "
