End character:
Total characters in a command should not be more than 60 (it actually cannot be 60). A end symbol, Chr(10)
, should be added at the end of each command in case of misunderstanding. It is suggested that the end
symbol was written using programming language so that it is not necessary for adding at the each end of
command. Besides, it cannot be forgotten neither.
Separating character:
A series of characters and numbers in the programming commands can be written in succession. But for
more clear and easy to read, separating character can also be inserted between the appropriate commands.
The position and the numbers are not limited. The instrument will not handle the blank separating characters
and will not be affected by them when executing commands.
Control ability:
Programming commands can almost control all functions of the machine only except for adjusting knob,
exterior measuring function, system setting, parameter calibration and power switch.
Application program
The so-called applied program is the control program writing by user so as to control instruments in auto-
testing system. Before writing program, user should read this book carefully and be familiar with the usage
of the analyzer. It is actually easy for the using of the program. Using programmable codes write the
program according to the manual operation. User can write out the appropriate applied program by the
present book.
