PARAMETER PROTECTION

PARAMETER PROTECTION
Moving from one run time parameter group to another, the
instrument will show, first, the group number (on the upper
display), the mnemonic code (on the lower display) and the
security status (on the middle display) of the group.
The possible security status are:
Enb

= the parameters of this group are not protected and they

may be modified;

inh

= the parameters of this group are always protected and

they cannot be modified;

- - - - = the parameters of this group are software protected.

In this case, by using “ “ and “ ” push-button, set a
value equal to the security code programmed during the
"Run time security code " (see page 18) and then push
“FUNC”.
If the programmed value matches the security code, the
parameters of this group can be modified otherwise they
will remain protected.

CAUTION

CAUTION: A software key protects one or more run time
parameter groups so that when the software key is set, it is
possible to modify the run time parameters of all groups.
The software protection will be automatically restored when the
instrument reverts to the "normal display mode" (by "MENU" push-
button pressure or by the time out).

RUN TIME PARAMETER MODIFICATION

By “MENU” push-button it is possible to start the run time
parameter modification by selecting desired run time parameter
group.
During the run time parameter modification, the upper display
shows the selected parameter group, the lower display shows
the mnemonic code of the selected parameter while the middle
display shows the value or status assigned to the selected
parameter.
The parameter monitoring and modification are bound by time
out (see “t.out” [C.I08] parameter), after that, the display returns
in “Normal display mode” and the modification (if carried out) of
the last displayed parameter will be lost.

NOTES

NOTES:
1) In the following pages we will describe all the parameter of

the instrument but it will show only the parameters related
with the specific hardware and in accordance with the
specific instrument configuration.

2) If all the parameters of a group are not available, the entire

group will not be displayed.
