Bump Test
Bump Test is used to check the response of the sensor with the indication of response limited to the display only.
The results of the bump test will not affect the reading register on the Modbus™ output.
The menu item appears as:
Bump Test
From the Bump Test 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
Bump Test

).
The display will return to normal operation alternating between the live gas reading and showing
Bump

minutes expires or the execution of a momentary hold over
PGM1
or
PGM2
, when the display will scroll

Restore Defaults
The CXT-IR sensor has the option to restore its internal memory settings to factory default conditions.
The menu item appears as:
Restore Defaults
.
NOTE
: Restoring factory defaults should only be used when absolutely necessary. All previously
existing configuration inputs will have to be re-entered if this function is executed. A full 10-second
magnet hold on PGM 2 is required to execute this function.
From the Restore Defaults text scroll, hold the magnet over
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
Defaults Restored
).
The display will then revert to
Restore Defaults
text scroll.
Move to another menu item by executing a momentary hold, or, return to normal operation via automatic timeout
of about 15 seconds (the display will scroll
Restore Defaults
four times and then return to normal operation).
CAUTION
After the defaults are restored, the sensor must be recalibrated.

The CXT-IR sensor communicates wirelessly and can be set to use unique wireless radio channel. Set RF
Channel is used to set the RF radio channel. It is adjustable from 0 to 15.
The menu item appears as:

.
From the Set RF Channel text scroll, hold the programming 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 Set Channel). The display will then switch to
XX
(where XX is the current RF channel). Swipe the
magnet momentarily over
PGM2
to increase or
PGM1
to decrease the hexadecimal number until the desired ID
is displayed. Hold the magnet over
PGM2
for 3 to 4 seconds to accept the new value. The display will scroll
Channel Saved
, and revert to
Set RF Channel
text scroll.
Move to another menu item by executing a momentary hold, or, return to Normal Operation via automatic
timeout of about 15 seconds (the display will scroll
Set RF Channel
four times and then return to Normal
Operation).
