System Organization
The Model Mini-ICS has two types of operational modes
– User-type, and Run-type. “User” modes
are initiated and controlled by the user, and are used to setup and maint
ain the analyzer. “Run”
modes are accessed automatically by the Model Mini-ICS during normal operation, according to its
programming, and its configuration parameters.
3.2
USER Modes
The user can initiate User modes either from the front panel or through the Service Port (section
4.1.1
– 4.1.2). Gas Calibration, Set O

Alarm, Set High ICS Limit, Set Low ICS Limit, and View
Active Faults modes will be covered in this chapter. System Configuration modes will be covered
in section 4.1.
3.2.1 CALIBRATE Mode
Calibration mode allows the Oxygen Sensor to be tuned to a gas of known Oxygen concentration
for the most accurate on-line reading at all times. As with all of the User modes of operation, you
will enter the CAL mode at the front panel from any “Run” mode by pressing the “MODE“ button.
