MAINTENANCE/TROUBLESHOOTING
The NO Calibration Source
is designed to be nearly maintenance-free. The only
component that requires routine maintenance is the NO scrubber, which should be
changed at least once every six months of operation. Other user serviceable
components include the lamp and air pump, both of which are easily replaced should
they fail.
Cleaning:
The exterior may be cleaned with a damp cloth after disconnecting the
power adapter. Be sure that the instrument is dry before applying power. If the flow
path becomes contaminated because of exposure to high levels of dust, smoke or
chemical vapors, the instrument should be returned to 2B Technologies for cleaning of
the internal flow path.
Calibration:
Every analytical instrument is subject to some drift and variation in
response, making it necessary to periodically check the calibration. We recommend
calibration at least annually. The instrument may be returned to 2B Technologies for
calibration servicing.
Troubleshooting:
If the instrument fails to operate correctly, common problems can
be identified and corrected using Table 5.1 (next page).
Technical Support for Calibration and Troubleshooting:
For calibration
assistance or if a problem cannot be easily corrected, please contact Customer
Service at 2B Tech via our web ticketing software at:

Alternatively, you can email us at
or call us at +1(303)

will provide you with a Return Authorization number and a short form to be filled out
and returned to our Service Department along with the instrument.
The figures following Table 5.1
provide a “guided tour” of the instrument so that critical
components and connectors may be easily identified.
