4.Select the channel (sensor) to be configured and adjust the sensor’s range using the up-down arrow keys (switch 1) or (switch 2). The specific sensor provides the upper limits/ranges.

Note: If no selections appear when activating the up/down arrow keys at this stage, the specific sensor only has one upper limit/range, which cannot be altered.

5.Activate the enter key (switch 3) when the desired upper limit/range is reached.

6.To exit, select “Exit” at each menu stage (sub menu and main menu).

4.3.6Select Gas Type

“Select Gas Type” option allows the user to select a particular target gas and/or Correction (“K”) Factor in the case of Catalytic Bead sensors or choose the type of LEL gas (gas curve) in the case of IR sensors. See specific sensor manual in relation to this menu option.

4.3.7 Calibration gas value

This option allows the user to select the calibration gas value in the transmitter main menu. Although it is recommended that 50% span gas should be used for calibration, for some sensors, the transmitter will allow tolerance/flexibility in the calibration gas available; 10% to 60% span gas allowed for some sensor types. See specific sensor manual.

1.Enter the main menu by activating any key to get the “enter main menu” prompt, then activate switch 1 to select “yes”.

2.Activate the up key (switch 1) or down key (switch 2), until “Cal. Gas value” option is displayed.

3.Activate the enter key (switch 3). Channel1 and channel 2 existing calibration gas values will be displayed in three numeric groups: ‘hundreds’, ‘tens’, and ‘ones’. For example: 0 5 0 indicates a calibration gas value of 50% span.

4.Highlight the required channel with calibration gas value using the navigation keys (switch1) or (switch 2), then select using switch 3. Switch 1 is used to increase /change a value in each numeric group, while switch 2 is used to cycle across the numeric groups.

5.To exit, select “Exit” at each menu stage (sub menu and main menu).

4.3.8Serial Number & Firmware Version

This option is used when the serial number or firmware version of the Millennium II Transmitter is required.

1.Enter the main menu by activating any key to get the “enter main menu” prompt, then activate switch 1 to select “yes”.

2.Activate the up key (switch 1) or down key (switch 2), until “Serial Number and Firmware Version” option is displayed.

3.Activate the enter key (switch 3). The firmware version and serial number will be displayed.

4.To exit, select “Exit” at each menu stage (sub menu and main menu).
