– Adjusting/reading the 4 … 20 mA interface – lower limit
aOPA<value>! aOPA<value<cr>
Adjust lower limit
aOPA! aOPA<value<cr>
Read out lower limit
a

<value>
–
pb.a
p
– Sign (+,–)
b
– Digits prior to the decimal point
b
– Digits after the decimal point
Number of spaces: 6 (5 decimal point)
Note the following settings for the units
m
→
pbb.aaa
Input in m (–30.000 … +30.000)

0
= 4 … 20 mA interface deactivated
(only the SDI-12 interface is active)
1
= 4 … 20mA and SDI-12 interface are active
2
= 4 mA output (constant value)
