using DOS executable extension (such as .EXE, .BAT, .COM, etc.). Note that pressing the and
keys will not ask for a file name to be entered, and measured data will not be saved.
Sequential measurements using identical operating parameters can be performed if the base name
ends in a number (i.e. group1) and the default file name is selected for subsequent measurements
(group2, group3,...). Do not type in the default name, just press ENTER when the default name is
displayed. The instrument will then utilize all the same operating parameters as the last measurement.
The CI-340 utilizes a shift key feature to accommodate many functions it has to offer. To register
alpha-characters (such as A, H, R, etc.), use a sequence of the
key followed by the respective
key to obtain the letter. Pressing the
key once accesses the first letter of the keys, twice does
the second, and three times, the third. No
key pressed in this sequence accesses the number
values. Note that the symbols (+, -, etc.) in the keys are not recognized if naming a file, and in turn
will show up as the respective number key. Press the
key to continue to the time interval setup.
The
key can be used as a backspace key and the can be used to clear the SHIFT count if
the key was accidentally pushed.
For example, the filename “GROUP1.C50” can be entered as follows:
Press
key after a file name is entered.
The time interval entry follows the entry of the filename step:
Time interval ?
___ (sec)
The analyzer’s sampling rate is then averaged by the interval input. The instrument’s sampling rate is
approximately once a second. The CI-340 will only recognize integer divisions (1 ~ 32768 seconds).
The instrument will not register letters of symbols. Pressing the
key saves the resulting
filename and time interval, respectively. Note that entering a file name twice will display “duplicate
