NOTE
The arrow prompts (
◄ and ►) will show that the magnetic switch is activated during the 3
second hold period.
The ITM will enter program mode and the first menu item View Sensor Status will be displayed. Hold the
magnet over PGM1 or PGM2 while the current menu text is scrolling to advance to the next menu item.
At the conclusion of the text scroll the arrow prompt ("
►" for PGM2 or "◄" for PGM1) will appear,
immediately remove the magnet. The ITM will advance to the next menu item. Repeat this process until the
desired menu item is displayed.
NOTE
PGM1 moves the menu items from right to left and PGM2 moves the menu items from left
to right.
To enter a menu item, hold the magnet over PGM1 or PGM2 while the menu item is scrolling. At the
conclusion of the text scroll the "
►"prompt ("►" for PGM2 or "◄" for PGM1) will appear, continue to hold
the magnet over PGM1 or PGM2 for an additional 3 to 4 seconds to enter the selected menu item. If there is
no magnet activity while the menu item text is scrolling (typically 4 repeated text scrolls), the ITM will
automatically revert to Normal Operation.
3.4.1 View Sensor Status
View Sensor Status displays all current configuration and operational parameters including:
• CX-IR ##.##
• Serial Number
• Range ###
• Autospan Level ##
• Modbus ID ##
• Last Cal ## Days
• Sensor Life ###%
• Temperature ##C
From the View Sensor Status text scroll, hold the magnet over PGM1 or PGM2 until the arrow prompt
appears and continue to hold the magnet in place for an additional 3 to 4 seconds (until the display starts to
scroll Status Is). The display will scroll the complete list of sensor status parameters sequentially.
When the status list sequence is complete, the ITM will revert to the View Sensor Status text scroll.
The user can either:
• review list again by executing another 3 to 4 second hold,
• move to another menu item by executing a momentary hold over PGM1 or PGM2, or
• return to normal operation via automatic timeout of about 15 seconds (the display will scroll View
Sensor Status four times and then return to normal operation).

The two selections are;
• %LEL and
• %VOL.
