Procedure for calibrating the Model Mini-ICS

3.2.1.3.1 Apply calibration gas to the Oxygen Sensor
Apply calibration gas to the Oxygen Sensor at a similar flow rate and pressure to that of the
sampled gas. Be sure to flow calibration gas to the sensor until the display has stabilized to allow
calibration gas to sweep out the sample lines. The analyzer includes an additional stabilization
period of 30-seconds at the beginning of its Calibration routine (user configurable – section 4.1.2).
If you are using a Neutronics Process Sampling System, or Process Sample Conditioning
Package, follow the instructions in the equipment manual for applying calibration gas to the
apparatus. If you have been supplied a Remote Calibration solenoid valve with your system, and
have installed it according to applicable instructions, manual application of calibration gas is not
necessary. The calibration valve will automatically control the flow of calibration gas to the sensor
when you enter CAL mode.
3.2.1.3.2 Enter CAL mode, and set calibration gas concentration
After a regulated stream of calibration gas has been applied to the sensor (or a Remote Calibration
solenoid valve is being used), press and release the "MODE" button once.
The 7-segment
alphanumeric display will show "o" while depressed. When the "MODE" button is released, the
display will show alternately "CAL", then an Oxygen concentration value. Adjust the displayed
Oxygen concentration value to read the applied calibration gas Oxygen concentration, or if you are
using compressed or ambient air, 20.9% Oxygen, by pressing the "UP" or "DOWN" arrows as
required.
3.2.1.3.3 Initiate Calibration routine
After you have set the calibration gas concentration, press and hold the "MODE" button for 3-
seconds until the 7-segment alphanumeric display shows "----". After the "MODE" button is
released, the display will show alternately "ACAL", and the Oxygen concentration value previously
set to indicate that the analyzer has begun its calibration routine.
Once initiated, the Model Mini-ICS will complete the calibration routine in 90-seconds without
additional input from the user. The analyzer will then resume RUN mode operation if no additional
user-input is received.
3.2.1.3.4 Return the Oxygen Sensor to on-line service
Be sure to flow sample gas to the sensor until the display has stabilized to allow time to sweep the
sample lines clear of calibration gas. The analyzer includes an additional stabilization period of 30-
seconds at the end of its Calibration routine (user configurable – section 4.1.2).
If you are using a Neutronics Process Sampling System, or Process Sample Conditioning
Package, follow the instructions in the equipment manual for removing calibration gas from the
apparatus, and returning it to process sampling. If you have been supplied a Remote Calibration
solenoid valve with your system, and have installed it according to applicable instructions, the
calibration valve will automatically return the flow of sample gas to the sensor as part of the
calibration routine.
