Comments:
1. Factory settings are highlighted.
2. With particular setting parameters the device cannot display the necessary minus sign due to the re-
striction to four segments. The parameters are configured as follows:
di.Lo:
-999 è 4 mA
di.Hi:
9999 è 20 mA
With an input measured current of 3.8 mA the correct display should be "-1068". Due to the restriction to
four segments, the minus sign is removed and the display is "1068".
3. With particular setting parameters the device cannot actually display the necessary 5 figures due to the
restriction to four segments. The parameters are configured as follows:
di.Lo:
-999 è 4 mA
di.Hi:
9999 è 20 mA
With an input measured current of 20.8 mA the correct display should be "10548". Due to the restriction to
four segments, the first character is removed and the display is "0548".
