It is possible to change meter parameters:
- from the meter keyboard ( p 5.1)
- through RS-485 (p.6.)
5.1. Change of the NA5 meter parameters from the keyboard
The pressure of the
key during circa three seconds causes the display
of the
seC
.
Inscription alternately with the set zero value by the manufacturer. The intro-
duction of the correct code causes the entry into the programming mode. The fig.6
represents the transition matrix into the programming mode. One can move on
groups of main parameters eg:
Ch1
,
Ch2
,
bAr1
,
bAr2
,
Al1
,
Al2
, etc, by means
of the
key.
The pressure of the
key on the given level, causes the entry into parameters of
this level. The moving on the given level is operated by means of the
key.
In order to change the value, one must use the
key. In order to escape from
the parameter change, one must press the
key.
By means of the
key, one can exit from the selected level and programming
matrix to the measurement.
