Note:
1. The minus sign is displayed in the most significant digit, together with 1. The display
range is -199.9...999.9 if di.P = ---.-,
2. When setting the signal limits, take into account that in some cases the correct value
cannot be displayed though there is no error indication.
Example 1:
di.Lo: -999 -> 4 mA di.Hi: 9999 -> 20 mA
For the input current of 3.8 mA the correct indication should be “-1068”. Actually “1068”
will be displayed.
