Mode of Measurement
The Orion 2230XP Silica Analyzer is designed to provide on-line process measurements, and
has two modes of operation. The mode is always displayed at the bottom right, i.e., below the
Info field and above the status field of the display.
The two modes of the instrument are AUTO restart mode (the instrument resumes auto
analysis mode after 0.5 Hr of inactivity) and MANUAL restart mode. The instrument awaits the
user to initiate the RUN or AUTO ANALYSIS mode by pressing the RUN key.
To change the instrument mode, from MAIN MENU follow the sequence:
MENU
➔
SETUP
➔
(+) ANALYSIS PARAMETERS
➔
MODE
The instrument has two special keys to start and stop the measurement. Pressing the RUN key
starts the auto analysis immediately and analysis repeats at the rate of the time set in
measurement frequency, which is selectable. During this mode, the instrument displays RUN
MODE indicating that the instrument is running continuously.
To edit the measurement frequency, from the MAIN MENU follow the sequence:
MENU
➔
SETUP
➔
(+) ANALYSIS PARAMETERS
➔
SAMPLE
FREQUENCY
The STOP key aborts the measurement at any stage irrespective of the mode of the instrument.
NOTE:
RUN is not the mode of the instrument. It indicates that the instrument is
performing measurement continuously, at the rate of measurement
frequency.
Auto Restart Mode
The default mode of the instrument is auto restart. In this mode, if the instrument keypad is
untouched (i.e. stays idle) for the period of auto restart idle time (default value of 30 minutes),
then it automatically starts the measurement, the mode is displayed as RUN MODE and
repeats the measurement as per the measurement frequency set in analysis parameters.
