7. SERVICE MODE
7-1. Introduction
Generally speaking their is no necessity to
adjust the settings of the service section. All
parameters are pre-programmed to values
(so-called defaults) enabling you to start
working immediately.
The advanced functions available through
this section are only needed in some specific
applications. This fine-tuning of the in stru-
ment gives a superior performance over
analogue 2-wire instruments.
If a function has to be adjusted it is called up
with the code mentioned. Having selected
the code then give you the possibility to eit-
her activate or adjust the values for this
function. After this you will return to the entry
point to make other adjustments or go back
to the measuring status.
If errors are made during the programming
process, these will be indicated, no action
will be taken and you can start the program-
ming again
