2.2.4

Minox i Oxygen Transmitter User Manual
The Minox i oxygen transmitter operates using a 2-wire industry-standard 4…20 mA loop-powered supply which you must provide.
Once the Minox i is connected to your process, it is ready to be connected to your power supply. To do this:
1. Align the pins in the Minox i electrical signal connector with the M12 mating connector on the cable. The cable connector can then be gently pushed into place.
2. Rotate the fastener clockwise until finger tight. Your Minox i oxygen transmitter is now connected. A pulsing red LED will indicate it is operating correctly.
Install your sensor
The sensor supplied should only be removed from the sealed package when the transmitter is installed and ready to make a measurement.
Installing the sensor is straightforward, but should be done quickly to limit exposure to ambient O2 levels, this is particularly important for the EC ppm sensors. Prolonged exposure to air will shorten the operational life of the sensor.
As a guideline, you should install the sensor into the Minox i, and the mount the transmitter in the measurement environment in 15-30 seconds. To install the sensor, please see “4.2 Replace the sensor” on page 13.

Calibration

NOTE: Calibration should be carried out by an appropriately trained or suitably qualified person.
The oxygen sensor output will decrease over time, and periodic calibration will be required. This is a non-intrusive procedure, achieved by using the MagTip one-touch calibration tool included with your Minox i.
Calibration cycles for the Minox i depend on the application, the applied gases, and the sensor type. They can be carried out in-situ or after safely removing the oxygen transmitter from your process in a bench test.
NOTE: For optimal calibration, the atmosphere surrounding the sensor must be ambient air (20.9 % volume O2) with no contaminants present. This can be achieved using an oxygen analyzer or by flushing the system with clean, oil- free compressed air.
The Minox i ppm must be calibrated in a controlled environment. Calibrating the Minox i % in ambient air will significantly reduce sensor life.
When the MagTip tool is applied, the indicator LED will flash six times in rapid succession. This confirms calibration is in progress.
During normal operation, the indicator LED will flash once every two seconds. This slower flash confirms Minox i is powered up and operational.
NOTE: The number of times the indicator LED flashes will vary on earlier models of Minox i.
