Neg. Analog Offset

The number on the first line is adjustable using the Up and Down

keys between 0 and 50. This function makes it possible to track negative
readings in the analog output, since the analog outputs do not go below
zero volts or 4 mA DC. Provided that negative readings are allowed (
this is set in the system menu as well ).

If the value is set to zero of FS (full scale), the analog outputs work

in standard form and this is the default.
