Turn OFF instrument and remove the AC power cord.
NOTE:
Turning off the instrument returns the Factory menu to restricted access.

Once the unit is reassembled, reconnect the AC power cord and turn it back on. Allow it to complete the warm
up (60 seconds) and confirm no faults are displayed. This completes replacing the NDIR Sensor.
6.6. NDIR Sensor Adjustment
It may become necessary to adjust the emitter and detector components of the NDIR sensor without actually replacing the
NDIR sensor. Such instances may present themselves as clipping faults (fault code 8000), DigiPot range errors (fault code
0200), and other faults. If you suspect a sensor adjustment may be in order, or if you are directed to adjust your NDIR sensor’s
DigiPot settings by a Bacharach service representative, then use the
IR Emitter Adjustment
and
IR Detector Adjustment
components of the NDIR Sensor Replacement procedure found in the previous section.
NOTE:
“DigiPot” is a shortened version of
digital potentiometer
. The H25-IR PRO uses DigiPots to simplify certain
configuration processes by integrating the manual tweaking process of an internal potentiometer into the user
interface. If, for example, minor adjustments need to be made to the NDIR sensor power settings, the operator
can use the front panel buttons and display panel to make the adjustments (versus opening the case, attaching
a voltmeter to test points on the printed circuit board, and tweaking a potentiometer with a small screwdriver).
