780/781 pH/Ion Meter - Operation via RS232
1.1 Call up of objects
All objects of the 780/781 pH/Ion Meter are grouped hierarchically in a
tree structure:
Language Prog
Aux
Config
&
Root
RSSet
Mode
3rd node
2nd node
1st node
0st node
Rules Example
The root of the tree is designated by &.
The branches (levels) of a tree are marked with a
dot (.) when calling up an object.
When calling up an object, it is sufficient to give
only as many letters as necessary to uniquely
assign the object. If the call is not unequivocal, the
first object in the series will be recognized.
Calling up the dialog language
&Config.Aux.Language or
&C.A.L
Upper- or lowercase letters may be used. &C.A.L or &c.a.l
An object can be assigned a value. Values are
signified at the beginning and end by quotes (").
They may contain up to 24 ASCII characters.
Numerical values can contain up to 6 digits, a
negative sign, and a decimal point. Numbers with
more than 6 characters are not accepted; more
than 4 decimal places are rounded off. For
numbers <1, it is necessary to enter leading zeros.
Entering the dialog language:
&C.A.L"english"
correct entry of numbers:
"0.1"
incorrect entry of numbers
"1,5" or "+3" or ".1"
The current object remains until a new object is
called.
entry of another dialog language:
"deutsch"
New objects can be addressed relative to the old
object:
A preceding dot leads forwards to the next level
in the tree.
From the root to node 'Aux':
&C.A
Forward from node 'Aux' to 'Prog':
.P
More than one preceding dot leads one level
backwards in the tree. n node backwards require
n+1 preceding dots.
Jump from node 'Prog' to node 'Aux'
and select a new object 'Language' at
this level:
..L
If you must jump back to the root, enter a preceding
&.
Change from node 'Language' via the
root to node 'Mode':
&M
